Hengshui High School Biology Required Knowledge Point
Hengshui High School's biology compulsory knowledge point had the following characteristics: 1. ** Cell division ** - ** Specialties ** - [Universal]: It exists in the biological world. - [Durability: Perpetual throughout the entire life process of the organism.] - [Irreversibility: Generally, differentiated cells will remain in the differentiated state until they die.] - ** stability **: The genetic material will not change during the process of division. - [Meaning: It is the basis of individual development (organ formation and functional perfection). It allows the cells in multi-celled organisms to specialize, form different tissues and organs, and improve the efficiency of physiological functions.] - [Essence: It is the result of the selective expression of luxury genes in cells under specific time, space, and environmental conditions. The DNA is not lost.] Housekeeping genes were genes expressed by all cells, and their products were necessary to maintain the basic life activities of cells, such as respiratory gene and ATP-cleaving gene. Luxury genes were genes specifically expressed by different types of cells, and their products endowed different cells with specific physiological functions, such as hemoglobin-like gene and insolin-like gene. 2. It also covered cell biology and many other aspects of knowledge. The knowledge points were rather fragmented, and there was a lot of content that needed to be memorized. It also required understanding and thinking. These knowledge points could be used in the mid-term exam, final exam, and academic level test. Read more exciting novels for free
Knowledge Concept Chart of High School Biology
High school biology compulsory knowledge summary
1. ** Levels of life system **: The cell is the most basic life system on Earth. The life system is arranged from small to large as cell → tissue → organ → system → individual → population → community → ecosystem → biosphere. 2. ** Cell classification **: According to the cell's nucleus without a nuclear membrane as a boundary, it is divided into two categories: eukaryonic cells and protokaryonic cells. 3. ** The material foundation of life ** - ** protein **: The basic unit that makes up protein, all life activities are inseparable from protein, and it is the main bearer of life activities. - Nucleic acid: A substance that carries genetic information in cells. It plays an extremely important role in the genetic variation of organisms and the synthesis of protein. - ** Carboids **: The main energy source. - ** Fat **: A good energy storage material in the cells. The carbon chain was the backbone of the biological molecules, and the basic unit was called a single unit. For example, the single unit that made up the acid was a single acid, and the single unit that made up the sugar was a single sugar. - [Water]: It exists in the cell in the form of bound water (combined with other substances in the cell) and free water (existing in a free form and can flow freely). - ** Salt **: Most of the cells exist in the form of ions. 4. Cell theory: It was mainly established by the German botanist Schleiden and the zoologist Schwann. The content included that cells were an organism, and all animals and plants were developed from cells and composed of cells and cell products. A cell was a relatively independent unit that had its own life and played a role in the overall life formed by other cells. New cells could be produced from old cells. 5. ** Cell membrane and biological membrane system ** - The cell membrane was mainly composed of fats and protein. Phospholiptides and steroids in fats were important components of the cell membrane. Their functions were to separate the cell from the external environment, control the entry and exit of substances into the cell, and carry out information exchange between cells. - The membrane system of a living organism was composed of an organelle membrane, a cell membrane, a nuclear membrane, and other structures. The composition and structure of these biological membranes were similar, and they were closely related in structure and function. 6. Nucleus: It is the genetic information bank that controls the metabolism and inheritance of the cell. It is the control center of the cell's metabolism and inheritance. 7. ** Material Transportation ** - Protoplasma layer: The cell membrane and tonoplasts, as well as the plasma between the two membranes, are called the protoplasma layer. When the concentration of the cell fluid was lower than the concentration of the external solution, the cell would lose water, and the protoplasma layer would be more elastic than the cell wall. It would gradually separate from the cell wall and undergo plasminal separation. - Passive transport: The substances entering and leaving the cell through simple diffusing is called free diffusing; the substances entering and leaving the cell through the carrier protein is called assisted diffusing (the diffusing along the concentration slope is collectively called passive transport). - [Active Transport: Transport from the low concentration side to the high concentration side requires the assistance of carrier protein and consumes the energy released by the chemical reaction in the cell.] 8. ** Cell metabolism ** - The many chemical reactions that take place in cells at all times are collectively called cell metabolism. The energy required for a molecular to change from a normal state to an active state that was prone to chemical reactions was collectively called activation energy. The effect of an electron on the activation energy was even more significant. An electron was an organic substance produced by living cells that had the ability to catalyze. Most of the electron was a protein, and a few of them were a protein. The chemical reactions that the electron was used to catalyze were generally carried out under relatively mild conditions. - ATP-is a high-energy phosphorous acid compound in cells. The process of cell metabolism referred to the process in which organic matter underwent a series of decomposition in the cell to produce carbon dioxide or other products, releasing energy and producing ATP. Aerobic metabolism referred to the process in which cells, with the participation of oxygen, completely decompose organic matter such as glucose through the catalyst of various kinds of membranes to produce carbon dioxide and water, releasing energy and producing a lot of ATP. 9. ** Photosynthesis ** - The four light energy absorbing substances were distributed on the thylakoid membrane of the plastids. The plastids were the place for photosynthesis. - Photosynthesis referred to the process in which green plants used light energy to convert carbon dioxide and water into organic matter that stored energy and released oxygen. It included the light reaction stage (light was required to carry out) and the dark reaction stage (light or not). 10. ** Cell reproduction ** - The relationship between cell surface area and volume limited the growth of cells, and the size of cells was also limited by the control range of the nucleus. Before cells split, they had to undergo material preparation. Cell reproduction included the continuous process of material preparation and cell division. A cell that continuously divided began when one division was completed and ended when the next division was completed. It was a cell cycle. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

For example, glucose is the main energy material needed for cell life activities; Lipids include fats, lysomes, and steroids. Different fats have different functions. For example, fats are good energy storage substances in cells. High school biology had a total of 88 basic knowledge points. Most of the biology questions were relatively simple, and about 80% of them were knowledge points that were often tested. There were not many basic points in the overall examination. He needed to systematically comb through each chapter and summarize his mastery of these basic points. Then, he needed to practice the basic questions to master them. He could also strengthen his memory of the basic knowledge by constructing a knowledge network (such as mind map method, triple knowledge network map, etc.), as well as by digging out and writing from memory. At the same time, he had to pay attention to the use of color to mark the common test points and difficult points so that he could quickly memorize the key questions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
300 high school biology knowledge points summary
The following is a summary of some high school biology knowledge points: 1. The relationship between chemical elements and organisms: organisms contain a variety of chemical elements. These elements have different functions and effects in the body, such as forming compounds and participating in physiological processes. 2. The list of compounds in the cell: There are many kinds of compounds in the cell, such as sugar, fat, protein, and nuclear acid. Each of them has different structures and functions. For example, sugar is the main energy material, fat can store energy, and so on. 3. Nucleic acid was divided into DNA and DNA, and its basic units were respectively, DNA and DNA. 4. Identification of reducing sugar, fat, protein, and DNA in biological tissues: Use specific reagents for identification. For example, Fehling's reagent can identify reducing sugar and produce brick-red precipitations; Sultan III dye solution can identify fat and produce orange color, etc. 5. The characteristic of the membrane was that it was selectively pervious, allowing certain substances to pass through while preventing other substances from passing through. 6. The cell membrane's substance exchange function: The cell membrane can carry out substance exchange through free dispersion, assisted dispersion, active transportation, and other methods. 7. The similarities between mitochondria and plastids were that they both had a double-layered membrane structure, were related to energy conversion, and contained a small amount of DNA. 8. The comparison of eukaryote organelle: Different organelle had differences in structure and function. For example, the ER was the synthesis, processing, and transportation channel of protein and other molecular substances; the Golgi apparatus mainly processed, classified, and packaged the protein from the ER. 9. During mitosis, the changes of nuclear DNA, the nuclei of the nuclei, and the nuclei of the nuclei were as follows: during the interphase, DNA replication and the synthesis of related protein were carried out, and the DNA content was doubled; during the prophase of mitosis, the nuclei of the nuclei appeared, and at the anaphase, the nuclei of the nuclei split, and the sister Chromatids separated. 10. The source of ATP-in the body: It is mainly produced by cell breathing (both oxygen and oxygen free breathing) and photosynthesis. 11. [The destination of the ATP-binding in the body: It is used for various life activities of cells, such as muscle contraction and material synthesis.] 12. The comparison between light reaction and dark reaction in photosynthesis: the light reaction occurs on the thylakoid membrane of the plastids, producing oxygen, bound bound 13. The relationship between light energy utilization rate and photosynthesis efficiency: Light energy utilization rate refers to the ratio of the energy contained in the organic matter accumulated by the plant's photosynthesis to the sunlight energy that shines on the ground; photosynthesis efficiency refers to the ratio of the energy contained in the organic matter produced by green plants through photosynthesis to the light energy absorbed during photosynthesis. 14. The relationship between the external factors that affect photosynthesis and the improvement of light energy utilization: The external factors include light intensity, temperature, carbon dioxide concentration, etc., and appropriately increasing the value of these factors can improve the light energy utilization. 15. The metabolism of the three major nutrients in humans and animals: sugar, fat, and protein can be synthesized and decomposed in the body, and they can be converted to each other. 16. The comparison between the two types of breathing: Aerobic breathing produces a large amount of energy and requires oxygen to participate. The reaction site is mainly the mitochondria. The anoxia-less breathing produces a small amount of energy and does not require oxygen. The reaction site is the cellular matrix. In addition, there were also knowledge points about cell structure and function, gene expression, genetic laws, biological evolution, ecological systems, etc., such as cell membrane system, gene translation and translation process, Mendel's law of inheritance, modern biological evolution theory, etc.(Genetic frequency changes, isolation and speciation, etc.), the components of the ecosystem (producers, consumers, disposers, non-biological substances and energy), energy flow (one-way flow, step-by-step reduction), material circulation, and many other topics.
