The content of the second volume of the seventh grade biology report
Here are some content suitable for the second volume of the seventh grade biology handwritten report: ** 1. Blood transfusion and blood type ** 1. Blood type: discovered by Austrian scientist Karl Landsteiner, it has hereditary characteristics. 2. The principle of safe blood transfusion: Generally, the principle of blood transfusion of the same type is followed. However, in an emergency, patients with type A blood could slowly transfuse a small amount of type O blood. For healthy adults, donating 200 - 300 milliliters of blood each time would not affect their health. For voluntary blood donation, they had to meet the conditions of being 18 - 55 years old, healthy, and voluntary. There were also requirements for weight, blood pressure, pulse, and so on. ** 2. Digestive System ** 1. [Constitution: Composed of digestive tract and digestive gland.] 2. "Small intestine: It is the main place for digesting food and absorbing nutrients. There are digestive juices such as intestinal juice, intestinal juice, bile, and so on. Amylum is broken down into glucose here, protein is broken down into aa, and fat is broken down into fatty acid and glycerine." 3. The liver is the largest digestive gland in the human body. It secretes bile. Bile does not contain digestive hormones, but it has a significant increase in the digestive ability of fat. ** 3. Regarding the respiratory system ** 1. Lungs: The main organ of the respiratory system, the structure that completes the exchange of gases. 2. The throat is the passage through which gas and food pass, connecting the digestive system and respiratory system. 3. Tracheal: There is a C-shaped cartilaginous support on the wall, and phlegm can be formed in the trachea. ** 4. Blood composition and hormones ** 1. Pituitaries: can secrete growth hormones. If the secretion is too little, dwarfism will occur. If it is too much, giantism will occur. 2. Knowledge related to the role of various cell components in the blood could also be included in the handwritten report. ** 5. Cell aspect ** 1. Plant cells: The basic structure includes the cell wall (support, protection), cell membrane (control of the entry and exit of substances, protection), the plasma (liquid, mobile, there are vesicles inside, and many substances are dissolved in the vesicles), the nucleus (storage and transmission of genetic information), and the plastids (the site of photosynthesis). 2. [Animal cells: For example, oral cells have cell membranes (which control the entry and exit of substances), nuclei, and other structures.] He could also add some interesting little knowledge related to biology, stories of biologists, or explanations of some biological phenomena to make the handwritten report richer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Seventh grade, volume one, biology summary article
The following is a summary of the first volume of biology in the seventh grade: 1. Cell structure 1. ** Plant Cell ** - The outermost layer was the cell wall, which played a supporting and protective role. - The inner side of the cell wall was the cell membrane, which was thin and difficult to see under an ordinary optical microscope. It could separate the internal substances from the external environment and maintain the stability of the internal environment. - Inside the cell membrane was a colorless, transparent, jelly-like substance. There were mitochondria (cylindrical), plastids (oval, usually found in the green part of the plant's cells, which contained the green content of the leaves), and vesicles (there were many small vesicles in the young cells, and as the cells grew, they combined to form a large central vesicle. The cell fluid in the vesicle dissolved a variety of substances. The color of petals was related to the cyanidins in the cell fluid, and the color of cyanidins changed with the ph). - In the center of the cell, the nucleus was almost spherical. In young cells, the nucleus was located in the center. In mature plant cells, the nucleus was located in the thin layer of the plasma outside the central vacuole. 2. ** Animal cells ** - The outermost layer was the cell membrane, and its function was similar to the cell membrane of plant cells. - The plasma was located between the cell membrane and the nucleus. It was also a colorless, transparent, and jelly-like substance. There were mitochondria in the plasma. - The nucleus was located in the center of the cell, resembling a sphere. 3. ** Cell structure comparison between animals and plants ** - The similarities were that they all had cell membranes, a nucleus, and a mitochondria. - The difference was that plant cells had cell walls, vesicles, and plastids, while animal cells did not. ** 2. Cell Division and Growth ** 1. ** Cell division process ** - Animal cells: The cell membrane caved inwards from the middle of the cell, constricting into two cells. - Plant cells: A new cell membrane and cell wall form in the center of the original cell, splitting into two cells. - The law of cell division: The relationship between the number of cells after division n and the number of divisions m is m = 2. 2. ** Genetic material changes during cell division ** - Chroomes were made up of DNA and protein, and they were the carriers of genetic material. When a cell divided, the chopstick would duplicate. During the division process, the chopstick would be divided into two parts with the same shape and number, which would enter the two new cells. The new cell and the original cell had the same shape and number of chopstick, and the genetic material contained in them was also the same. - The cell division and growth rate of an organism were affected by environmental conditions. For example, tree rings were formed by cell division and growth rate due to different climates. In agricultural production, providing suitable conditions can promote cell division and growth of crops to increase yield. ** 3. Grappies and Reptiles (Take lizards as an example)** 1. ** Living habits and structure of lizards ** - Living on land, the body is divided into five parts: neck, torso, and limbs. There is a neck behind the head, and the head can be turned flexibly. Its four limbs were short, and it crawled close to the ground. Dry skin, covered with horny scales, can protect the body and reduce moisture. 2. ** Breath and procreate ** - Breathing with the lungs. The lungs were more developed than frogs, and their gas exchange ability was stronger. Their body temperature was not constant, and they were considered to be warm-blooded. - The method of fertilisation was internal fertilisation. The fertilized egg was produced on land. The fertilized egg was larger, and the egg contained a lot of nutrients and a certain amount of water. The egg was protected by a tough eggshell, and reproduction and development were free from the dependence on the water environment. 3. ** Main characteristics of reptiles ** - The body surface is covered with horny scales or armor, breathing with the lungs, body temperature is not constant, limbs are short or no limbs crawl. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The first part was the first chapter," The Origin of Man ". Through various teaching activities, students were guided to understand the origin and development of human beings, ontogeny and development, the characteristics of puberty development, and the cultivation of hygiene habits. The second part includes chapters 2, 3, 4, 5 and 6. With the human physiological activities as clues, students will understand the way human physiological activities proceed, the basic anatomical structure of the human body, and form a biological perspective on the adaptation of structure and function. At the same time, it will penetrate the biological perspective on the dependence, adaptation and influence of human life activities on the biosphere environment. The third part was Chapter 7," The impact of human activities on the biosphere." It focused on activities such as case analysis, simulation exploration, and planning to guide students to understand the close relationship between humans and the environment, emphasizing that people in the biosphere should protect the biosphere. This unit was not just about human biology. It was about putting the human body in the context of the biosphere or living environment to guide students to analyze and understand human biology or the relationship between human activities and the environment. It was a comprehensive science of human biology, human psychology, and environmental biology. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
