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. These knowledge points were all important parts of high school biology learning, but due to space constraints, it was difficult to list all 300. Read more exciting novels for free

Jiangsu junior high school biology knowledge summary
A summary of the key knowledge of senior high school chemistry and biology
Grade One Chemistry Key Knowledge: - Metals and their compounds: To master the main physical properties of metals such as Na, aluminum, iron, copper, and their important compounds. Na and aluminum only existed in the compound state, while iron and copper existed in the free state and the compound state. In terms of physical properties, the bulk sodium-aluminum-iron was a silver-white metal, while pure copper was a purple-red metal. The color of powdered aluminum and copper remained unchanged, while powdered iron filings were black. The rapid decomposition of Na in the air eventually turned into Na. The density of Na was lower than that of water, while the density of aluminum, iron, and copper was higher than that of water. The melting point of Na was low, while the melting points of aluminum, iron, and copper were high. They all had the commonality of being opaque, conducting electricity, conducting heat, and extending. At the same time, they also had their own characteristics, such as iron could be magnetized. In terms of the color of the compounds, white ones were Na <2> O <3> and AI <2> O <3>, black ones were FeO, FeO <2> O <3>, CuO, light yellow ones were Na <2> O <3>, and reddish-brown ones were FeO <2> O <3>. - In terms of learning methods, learning and memorizing chemistry was more important than practice. One had to first master basic knowledge such as equation writing, material properties, and related reactions. These basic test points often appeared in the college entrance examination questions. A summary of the key knowledge of biology in Grade One: - In terms of chemical elements that make up organisms, there are trace elements such as iron, Mn, B, Mn, copper, Mo, etc., and large elements such as carbon, oxygen, hydrogen, nitrogen, sulfur, phosphorous, calcium, potassium, and so on. It was necessary to understand the unity of the biological world and the non-biological world (the chemical elements that make up the cells can be found in the non-biological world) and the differences (the chemical elements that make up the biological world are different in the cell and the non-biological world). - In terms of the compounds that make up an organism, protoplasts include the plasma, nucleus, and cell membrane (excluding the cell wall), and the main components are nuclear acid and protein. There were bound water (which was a component of the cell structure) and free water (which was a reagent, involved in biochemical reactions, and transported substances). Most of the minerals exist in the form of ions, which are important components of some complex compounds (for example, iron is the main component of hemoglobin). They can also maintain life activities, acid and base balance, and osmolarity. Carboids were divided into monosomes (such as glucose, glucose, Ribose, and Deoxy Ribose), disomes (cane sugar and glucose in plants, and glucose in animals), and glycans (starch and starch in plants, and glycogen in animals). Lipids included fats (which stored energy and maintained body temperature), lipid-like substances (which formed membrane structures), and steroids (which maintained metabolism and reproductive processes). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Junior high school biology knowledge points, species variety
Species variety was an important component of biological variety. It was the most intuitive embodiment of biological variety and also the core of the concept of biological variety. The differences between individuals of different species reflected the variety of species. Biological species and species would affect the ecosystem. At the same time, the variety of genes determined the variety of species, and the essence of the variety of species was the variety of genes. China was one of the countries with the richest biological species. For example, the species of mosses, ferns, and seed plants in China were second only to Brazil and Colombia, ranking third in the world. China was also the country with the richest gymnosperm, known as the " hometown of gymnosperm." In terms of biological classification, organisms were divided into different levels of taxonomical units according to the degree of similarity between organisms. From large to small, they were kingdom, phylum, class, order, family, species, and species. Species was the basic unit of classification, and the same species had the closest kinship. The larger the taxon, the more species it contained, but the less similar the species were, the fewer common characteristics, and the farther the kinship was. The smaller the taxon, the fewer species it contained, and the more common characteristics, the closer the kinship was. The fundamental measure to protect the biological variety was to protect the habitat of living creatures and the variety of the ecosystem. The establishment of nature reserves was the most effective measure to protect the biological variety. It was of great significance to protect the species, genes, and ecological environment. It was conducive to the stability of the ecosystem and could also provide humans with more kinds of biological resources and scientific research materials. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
