Biological Blood Cell Diagram
The following are the basic characteristics of common blood cells: ** 1. Red Blood Cell (RMB)** 1. [Form] - It was in the shape of a double concave disc, thin in the middle and thick around, similar to the shape of a persimmon. This unique form gave it a large surface area. The surface area of all the red blood cells in the body added up to 2000 times the surface area of the human body. 2. ** Function and Specialties ** - It is the most numerous cell in the blood and is red because it contains iron-containing hemoglobin. Its main function is to carry oxygen and carbon dioxide throughout the body. Red blood cells were formed in the bone marrow, and the average lifespan was about 120 days. The aged red blood cells would be swallowed in the spleen, liver, bone marrow, and other places. Iron and protein would be recycled and reused. Under normal circumstances, the number of red blood cells would remain constant. On the test report, the red blood cell count and the concentration of the blood protein were the main items of concern. A drop in one of them could indicate that the patient was anemia-stricken. ** 2. White Blood Cell (White Blood Cell)** - It was the general term for the cells in the blood that were responsible for immune defense, including neutrons, infuriophils, basophils, monophils, and splenophils. 1. ** Neutrophs ** - It was the most numerous type of white blood cell. The cell nucleus had various forms. Some were sausage-shaped, while others were divided into several nuclei. Generally, the more lobes there were, the older the cell. When a certain part of the body was invaded by bacteria, it could penetrate the capillaries and gather at the infected part to devour the bacteria. After devouring the bacteria, it would die and become a pus cell. The proportion of these in the blood will be significantly increased due to bacteria infection, and antibiotics are suitable for use when there are more neutrons in the blood routine. 2. ** Eosophils and Basophils ** - It looked similar to a chopstick. - Eosiophils can weaken allergic reactions and can also combine with the surface of certain parasites to kill them. The number of allergic diseases or parasitic diseases will increase. - Basophils were mainly responsible for allergic reactions, and their numbers would increase when they suffered from inflammation, infection, and leukemia. 3. ** Monocells ** - It was especially large and contained a variety of membranes. After passing through the blood vessels and entering the tissues and body cavity, they could become engulfing cells. The engulfing and digesting abilities of the engulfing cells were enhanced. They could eliminate all kinds of microorganisms that invaded the body, swallow foreign particles, and remove aging and damaged cells in the body. Generally, fever accompanied by mononosis was a sign of viral infection. In a few cases, it was leukemia. 4. ** Lymph cells ** - According to the location, surface characteristics, length of life, and immune function, it can be divided into four types: T cells, B cells, killer (K) cells, and natural killer (N) cells. It was mainly involved in immunity, such as rejection of allogeneic transplants, anti-tumor, anti-virus, etc. After B cells were stimulated by the virus, they produced anti-virus and could "remember" the virus. The increase in the number of blood cells was more commonly seen in viral infection. Read more exciting novels for free
Biological cell working principle diagram
The working principle of cells involved many aspects: ** I. Basic structure and function of cells ** 1. ** Cell membrane ** - [Constitution: Mainly composed of the Phospholide Bilayers, protein, and sugar.] - Function: It is the control "checkpoint" for substances entering and leaving the cell. Through its structural characteristics of mobility and imbalance, it can achieve functions such as information exchange between cells and cell recognition. According to the number of layers of the membrane, it could be divided into different types such as single-layer membrane, double-layer membrane, and three-layer membrane. 2. ** Nucleus ** - The nucleus was the control center of the cell, storing and replicating genetic information. It exchanged substances and information with the cell through the nuclear pore and played a key role in the process of cell division and division. Chromatin in the nucleus was composed of DNA and protein. 3. ** Cell plasma ** - The plasma was a translucent, jelly-like substance in the cell that was composed of water, mineral salt, fat, sugar, and so on. It contained a variety of organelle, such as mitochondria, plastids, the plasmatic reticule, and the Golgi apparatus, each of which had different functions. For example, mitochondria and plastids were involved in energy conversion, the plastids stored and processed protein, the Golgi apparatus was involved in the synthesis and transportation of secreted protein, and the lysomes decomposed aging organelle and foreign microorganisms. The cell skeleton in the cell was composed of protein fibers, which maintained the cell's shape and internal structure. It also participated in life activities such as cell movement and division. The plasma was the main place for cells to carry out metabolism. Many of the membranes and reaction systems could decompose nutrients to release energy and discharge waste products. ** 2. Principles related to cell functions ** 1. ** Material Exchange ** - The plasma membrane controls the entry and exit of substances into the cell. The Golgi apparatus is involved in the synthesis and transportation of secreted protein. The lysomes decompose related substances to complete the exchange, processing, transportation, and decomposition of substances inside and outside the cell. 2. ** Energy Conversion ** - The cells convert chemical energy into the chemical energy in the ATP-like substance through the process of oxyphosphoridation. Mitochondria and the plastids are important places for energy conversion. During photosynthesis, the process of converting light energy into chemical energy also occurred in the cells. 3. ** Information Transfer ** - The signaling pathway in cells could transmit information to the nucleus to affect gene expression. This process was crucial for cell growth, development, and division. The cells transmit information through signal molecules, and the receptor on the cell membrane recognizes the signal molecules and sends the information into the cell. ** 3. Metabolic principles of cells ** 1. ** Material synthesis ** - The cells synthesize simple substances into complex substances, such as sugar, fat, protein, etc., through the action of the enzyme. The synthesis process required energy and material input, and the synthesized product was important for cell growth and function. 2. ** Matter breakdown ** - The cell uses the protein to break down large molecules into small molecules, such as glucose into methyruvate. The decomposition process may consume oxygen or water, and produce waste products such as carbon dioxide or ureas. The decomposition products can participate in other chemical reactions and release energy for cells to use. The material cycle covered the synthesis, decomposition, and energy conversion of substances. It was regulated by many kinds of membranes in cells and was closely related to cell structure and function. ** 4. Principle of Cell Division and Reproduction ** 1. ** Mitosis ** - This was a type of cell division, which involved the formation of the Spindle and the replication of the Chromosome. It included interphase, prophase, midphase, anaphase, and telophase. Its significance was to maintain the normal growth and development of the organism, maintain genetic stability, and be affected by genetic materials, cell cycles, environmental factors, and so on. 2. ** Amitosis ** - During the division process, there were no spindle-like fibers and embryos. The speed was fast and the genetic material did not undergo reorganization or cross-exchange. For example, the red blood cells of frogs and some protozoa underwent mitosis, which played an important role in the growth and development of organisms and tissue repair. 3. ** Meiosis ** - The number of embryos would be halved after the cells split twice. The reproductive cells (gametes) would be produced to ensure the stability and variety of the species 'inheritance. It also included the Interphase, Early Phase, Middle Phase, Late Phase, and Late Phase. ** 5. Principle of Cell Inheritance and Mutation ** - DNA replication was the basis of cell division and reproduction. During this process, DNA Polymerase catalyze the synthesis of base pairs to ensure the accurate transmission of genetic information. Genetic information was transmitted to the next generation of cells through DNA replication to maintain the genetic continuity of the organism. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Biological Cell Structure
The cell was the basic unit of life activity. Its structure was complex and delicate. Different types of biological cell structures had certain commonalities and characteristics. 1. ** Cell membrane ** - [Constitution: It is mainly composed of a Phospholide Bilayer-layer as the basic skeleton, embedded with protein, and there is also a protein outside the membrane.] - [Characteristic: Has a certain degree of mobility and selective penetration.] - [Function: Protects cells and controls the entry and exit of substances.] 2. ** Cell plasma ** - [Constitution: Including the cellular stroma and the organelle.] - Function: The cellular matrix provides a place, substances, and certain environmental conditions for metabolism. There are many types of organelle, each with its own unique functions. For example, the mitochondria (double-layer membrane structure) is the main place for the cell to breathe oxygen (the second and third stages) and contains a small amount of DNA.(double-layered membrane structure, found in the green cells of plants) is the site of photosynthesis; The plasmatic reticule, Golgi apparatus, Ribosome, and Lysosome also played an important role in the synthesis, processing, transportation, and digestion of substances in the cell. Centrosome in animal cells was related to mitosis (higher plant cells did not have centrosome). The vesicles in plant cells had functions such as storage, digestion, and regulation of infiltration. In most mature plant cells, the vesicles accounted for about 90% of the entire cell volume. 3. ** Nucleus ** - Constitution: It is composed of nuclear membrane, nucleus, and Chromatin. - [Function: It is the main place where DNA is stored and replicated. It acts as the control center for cell genetics and cell metabolism activities.] Procaryotes (such as bacteria) had cell walls, cell membranes, protoplasts, and karyomes. There was only one type of organelle, the Ribosome. The bacteria did not have a formed nucleus. The nucleus was a karyomidium formed by the accumulation of genetic material. The karyomidium did not have a nuclear membrane or a nucleus. Fungi had cell membranes, protoplasts, and nuclei. The protoplasts of fungi included the cellular matrix and the organelle. The organelle included the ER, the mitochondria, the Golgi apparatus, the Ribosome, the Lysosome, and so on. Animal cells did not have a cell wall, and the cell plasma of animal cells did not contain plastids, nor did it form a central vesicle. Plant cells were composed of protoplasts and cell walls. Protoplasts included the nucleus and the plasma. In addition, viruses have no cellular structure and are made up of genetic material and protein. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Complement Antibodies Biological Function Diagram
Antibodies have three main biological mechanisms of action: 1. [Neutralization]: Before the pathogen enters the host cell, it needs to bind to specific molecules on the cell surface, and the antibody-bound pathogen can prevent this binding from happening. 2. ** Opsonization effect **: Antibodies gather on the surface of the pathogen and promote the engulfing effect of the engulfing cells. Phagocytic cells use the Fc-receptor on their surface to recognize the pathogen binding to the protein and engulf it. 3. ** Complement Activation **: Antibodies covering the surface of the pathogen can activate the complement system. The complement that is bound to the pathogen will bind to the complement receptor on the cell, causing the pathogen to die. Some of the complement could recruit engulfing cells to the site of infection, and some of the terminal components of the complement could punch holes on the surface of the pathogen, forming pores to directly crack it. There were three ways to activate the complement system: 1. ** Classic activation pathway **: It is activated by specific anti-bodies (mainly IgGs and IgMs) that bind to the target. It is the main humoral immune mechanism of acquired immunity. In this pathway, C1q had to bind to more than two FC segments of the protein to undergo a conformational change and activate the bound C1r. Its C3 convertases were C4b2a and C5 convertases were C4b2a3b. 2. ** Substitute pathway **: Activating on the surface of the microorganisms in the absence of an immune system is an effective mechanism of innate immunity. C3 convertases were C3bBb, C5 convertases were C3bBb3b, and C3bBb could combine with C3b to form new C3bBb, which had a positive feedback effect. 3. ** Lectin Pathway **: Activated by mannose-binding protein bound to the surface of microorganisms. It is also the effect mechanism of innate immunity. The most important C3 convertase is C4b2a. Under normal physiological conditions, C3 was the most abundant complement in the body. C3b is produced during complement activation and can be fixed on the surface of bacteria or other particles. In a systematic bacteria infection, the complement active fragment plays an immune effect mainly through conditioning, and the complement cracking fragment with kinin-like effect is C2a. The complement system can enhance (replenish) the ability of the immune system to eliminate microorganisms and damaged cells, promote inflammation, and attack the cell membrane of the pathogen. It is an important participant in innate immunity and acquired immunity. The complement system is composed of about 50 kinds of protein and protein fragments, including serum protein and cell membrane receptor, which account for about 10% of the serum's globin. They are synthesized by the liver and circulate in the blood as inactive precursor. When stimulated by a trigger, the proteases in the system would cleave specific protein and initiate an amplification cascading reaction of further cleavage. Finally, it could stimulate the engulfing cells to eliminate the invading microorganisms, induce inflammation to attract more engulfing cells to participate in the immune response, and at the same time, it could form a cell membrane attack complex to directly kill the invading microorganisms. However, the activation and biological function of complement were limited to the surface of the microorganisms or the location where the antibody-bound to the antigen-binding site, not in the blood. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Principle of Biological Cell Regeneration
Biological cell regeneration was divided into physiological regeneration and pathological regeneration. It referred to the reproduction of the same type of cells in order to repair defects. Taking skin cell regeneration as an example, the skin was composed of the epicuticum, the corium, and the hypodermic tissue. When the skin was damaged, the stratum corneum in the epicuticum would split and regenerate to repair the damaged skin. In some lower animals such as turbellarians and salamanders, after their body cells were damaged by the outside world, they would obtain a certain degree of " flexibility " through the process of " de-differentiation ". After reaching an intermediate state, they would achieve limb regeneration. For humans, the stem cells in the body could differentiate into various cells and play different roles. In cell regeneration and repair, stem cells could differentiate into specific types of cells to replace damaged, sick, or aged cells and promote the self-repair and regeneration of tissues and organs. Chinese scientists were also trying to use chemical small molecules to induce and other technologies, such as reprogramming technology, to change cell fate through epigenetic modification without changing the gene sequence, so that human cells could achieve similar regenerative functions. In addition, Australia researchers found that a type of cell on the outer layer of the adult mouse's artery could be activated by damage or poor blood flow, transforming into cultured cells and engulfing cells. The cultured cells formed blood vessels, while the engulfing cells were responsible for tissue repair and defense, thereby achieving regenerative functions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to write the compound in the biological cell
The following is an example of how to write a notebook on chemical compounds in biological cells: ** I. Elements and compounds in cells ** 1. ** Elements ** - The unity of the biological world and the non-biological world was that the chemical elements that made up the living things were basically the same, and the difference was that the contents were different. - As a living element, carbon was mainly absorbed into the biological world through the photosynthesis of green plants. Other elements were mostly absorbed into the biological world through plant roots. 2. ** Compound Type ** - The chemical compounds in cells were divided into two types: organic compounds (water and salt) and organic compounds (sugar, fat, protein, and so on). ** 2. The organic substances in the cells ** 1. ** Water * - Form of Existence: - Free water: Most of the cells exist in the form of free water. For example, free water is mainly lost during the drying process of seeds. It is involved in a variety of physiological processes, such as photosynthesis, respiratory reaction, ATP-cleavage, glycan and protein cleavage, etc., which consume free water. However, free water will be produced during photosynthesis, respiratory reaction, ATP-synthesis, glycan and protein synthesis, etc. - Bound water: When the seeds are dried and heated, the water droplets that appear on the test tube wall are bound water. Without bound water, the cells may die. - [Water content: Water is the most abundant compound in human cells. Living cells contain the most water.] 2. ** Salt ** - [Existence form: Most of them exist in the ion state.] - Function: - For example, the plant's "flowers but not fruits" was a manifestation of Boron deficiency (B). - Magnesium (MG2) is related to the synthesis of plants 'photosynthesis. Plants with a lack of magnesium turn yellow and slow down the rate of photosynthesis; nitrogen (N) is related to plant leaves; potassium (K) is related to the synthesis and transportation of sugar in plants; Iodine (I) is closely related to the development of human intelligence. Iodine deficiency will lead to insufficient thyreoid hormones and lead to idiocy. ** 3. The organic compounds in cells ** 1. ** Sugar-based ** - "Classes: Including Monosomes (such as Ribose, Deoxy Ribose, etc.), Disomes, and Polymers. - [Function: Main energy source.] 2. ** Lipids ** - "Classes: Fat, Phospholide, Sterol, etc. - Function: Fat is a good energy storage substance; Phospholiptides are an important component of cell membranes; Steroids play a role in regulating physiological functions. 3. ** protein ** - The basic unit was the protein formed by the condensation and dehydration of the protein. - Diverse functions: Most of the zymes belong to the protein class. The protein also has many functions such as structure, transportation, regulation, immunity, and so on. 4. ** Nucleic acid ** - <Category: Including DNA and DNA.> - [Constitution: Composed of nuclei, carriers of genetic information.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Biological secondary sperm mother cell
Secondary sperm cells were the primary sperm cells that were produced after the first division of the primary sperm cells. It can undergo a second Meiosis, and two secondary sperm cells can develop into four sperm cells. It existed for a very short time, and soon after it formed, it entered the next division into sperm cells. The secondary sperm cells were haploids, and had no homolog. They were smaller than the primary sperm cells, and their nuclei were round. If there are a large number of secondary sperm cells and few sperm cells found in the testical puncture, there may be obstacles in the formation of sperm, and it is considered congenital sperm development disorder. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
