Creatures must memorize knowledge points seven on the People's Education edition
The following are the must-memorize knowledge points of the seventh grade biology book published by the People's Education Press: ** 1. Biological characteristics ** 1. Living creatures needed nutrients to survive. Living creatures needed to constantly obtain nutrients from the outside world to survive. For example, green plants produce organic matter through photosynthesis, and animals obtain food through hunting. 2. Living things can breathe: Most living things need to inhale oxygen and exhale carbon dioxide. 3. Living things can discharge waste produced in the body: for example, animals discharge waste through urine, sweat, and exhalation, and plants take away some waste through fallen leaves. 4. Creatures could respond to external stimulation, such as the mimosa closing its leaves when touched, and animals running away when they were in danger. 5. Creatures can grow and reproduce: Creatures can grow up from small and can reproduce offspring, such as the sprouting of seeds and the hatching of young chicks. 6. All living things had the characteristics of inheritance and variation. The similarity in traits between the offspring and parents of an organism was inheritance, and the difference was variation. 7. Other than viruses, all living things were made up of cells. ** 2. Biology and the environment ** 1. ecological factors - Abiotic factors: including light, temperature, water, etc. The influence of abiotic factors on living things, such as "the end of April in the human world, the peach blossoms in the mountain temple begin to bloom", reflected the influence of temperature on living things; there were oases near the water source in the desert, reflecting the influence of water on living things. - [Biological factors: It refers to other organisms that affect the life of a certain organism.] The relationships between living creatures included predatory relationships (like wolves eating sheep), competition (like rice and weeds fighting for sunlight and nutrients in a paddy field), cooperation (like ants working together to transport food), parasitism (like roundworms parasitizing in the human intestines), and so on. 2. Biological adaptation to the environment: For example, the roots of the Camel thorn are developed to adapt to the dry environment, and the fat under the skin of the seal is thick to adapt to the cold environment. Creatures could also affect the environment, such as the shade under a big tree (the effect of plant transpirations on the environmental temperature), and earthworms loosening the soil. ** 3. Cell structure and function (plant cells and animal cells)** 1. vegetable cell - Cell wall: The outermost layer of plant cells, which plays a supporting and protective role. - Cell membrane: It clings to the inner side of the cell wall, separating the substances inside the cell from the external environment, and maintaining the internal environment of the cell to be relatively stable. - The colorless, transparent, jelly-like substance between the cell membrane and the nucleus. There were mitochondria (providing energy for cell life activities), plastids (generally found in the green part of the plant cells, carrying out photosynthesis, containing the chopstick, making the plant leaves appear green), and vesicles (small and numerous vesicles in young cells, mature cells have a large central vesicle, and the cell fluid in the vesicle melts a variety of substances. The color of petals is related to the cyanidins in the cell fluid, and the color of cyanidins changes with the ph of the cell fluid). - Nucleus: It is spherical and contains genetic material. It is the control center of the cell. 2. animal cell - There was no cell wall, and the outermost layer was the cell membrane. There were mitochondria in the cell, and the nucleus was located in the center of the cell. It was a spherical structure. - Plant and animal cells shared the same structure: cell membrane, plasma, nucleus, mitochondria; plant cells had structures that animal cells did not have: cell wall, vesicle, and plastids. ** 4. The Life of the Cell ** 1. The life of a cell required substance and energy. The substances in the cells were divided into two types: mineral substances (such as water, mineral salt, etc.) and organic substances (such as sugar, fat, protein, and nuclei). 2. The cell membrane controlled the entry and exit of substances. It was selective towards substances. 3. The mitochondria and the plastids in the cell were energy generators. The mitochondria released chemical energy from organic matter for cell use, while the plastids converted light energy into chemical energy and stored it in organic matter (unique to plant cells). ** 5. The level of the organism's structure ** 1. The cells produce new cells through division. In the process of cell division, the first thing that happened was the doubling of the number of copies of the DNA. The DNA was then divided equally into two new cells. The new cells contained the same genetic material as the original cells. 2. The structure of an animal's body was as follows: cells, tissues (including the tissues of the skin, muscles, nerves, and tissues), organs, systems (such as the digestive system and respiratory system), and the animal body. 3. The structure of a plant: cells → tissues (meristematic tissues, protective tissues, conducting tissues, vegetative tissues, mechanical tissues) → organs (roots, stems, leaves, flowers, fruits, seeds) → plants (plants do not have a system). ** 6. The Life of a Green Plant ** 1. The structure of the seed - Kidney bean seed: composed of seed coat and embryo. Embryo includes embryo, hypocotyl, root, and leaf (two pieces, storing nutrients). - "The seed of corn is composed of the seed coat, embryo, and the embryo. The embryo includes the embryo, hypocotyl, radical root, and seed leaf (one piece, transporting nutrients). The embryo stores nutrients. 2. seed germination - [The environmental conditions are: suitable temperature, a certain amount of water, and sufficient air.] - [Self-condition: The embryo is complete, alive, and not in a dormant state.] 3. plant growth - The growth of the root depended on the division of the cells in the meristematic zone to increase the number of cells, and on the extension of the cells in the extension zone to increase the volume of the cells. - Branches developed from buds, and there were meristematic tissues in the buds. - Plants need nutrients to grow: water, minerals (the most needed are minerals containing nitrogen, phosphorous, and potash), and organic matter. 4. flowering and fruiting - The main structure of a flower is the stamen (anther and silk) and the pistil (Stigma, style, and ovaries). - Pollinating: The process of pollen falling from the anther onto the pistil's Stigma. There are two ways of pollinating: self and cross pollinating. - Fertility: The process of combining the sperm in the pollen tube with the egg cell in the ovule to form a fertilized egg. - Fruit and seed formation: The ovaries develop into fruits, the walls of the ovaries develop into fruit skins, the ovules develop into seeds, and the fertilized eggs develop into embryos.

Seven basic biological structure knowledge points PEP edition
The following are the basic structural knowledge points of the seventh grade biology book published by the People's Education Press: ##1. Cell structure 1. ** Common structure of animal and plant cells ** - Cell membrane: Separates the substances inside the cell from the external environment, allowing the cell to have a stable internal environment. - [** Protoplasm **: A colorless, transparent, jelly-like substance located between the cell membrane and the nucleus. The protoplasm contains structures such as mitochondria.] - Nucleus: It contains genetic material and is the control center of the cell's life activities. 2. ** Unique structure of plant cells ** - ** Cell Wall **: Located on the outermost layer of plant cells, it plays a supporting and protective role. - ** Bubble **: Plant cells have a bubble, which is filled with cell fluid and dissolved with a variety of substances. The color of flowers is related to the cyanidins in the petal cell fluid. The color of cyanidins changes with the ph of the cell fluid. In young cells, the number of vesicles was small and numerous. As the cell grew, many small vesicles would combine to form a large central vesicle. - <strong></strong></strong><strong></strong> ##2. Cell Physiology 1. ** Cell Division **: The increase in the number of cells is achieved through cell division. 2. Cell growth: The process of cell size growing from small to large is called cell growth. 3. [Cell division: The result of cell division is the production of different tissues.] ##3. Temporary Filming 1. ** Steps for preparing onion skin cells for temporary mounting **:(The specific steps are not detailed, but it involves the process of collecting materials, making slices, dyeing, etc.) - In the middle of the slide, clean water was added, and the dyeing process was the process of adding an iodine-based solution. 2. ** Steps for making temporary mounting of human oral cells **:(The specific steps are not given in detail, but it involves the process of collecting materials, making films, dyeing, etc.) - Normal salt solution was dripped in the center of the slide, and the cells were scraped from the inside of the mouth with a toothpick. - Pay attention to the operation specifications when covering the cover glass to avoid bubbles, and operate correctly when staining to ensure that the cell structure can be clearly observed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Biology elective, a must-memorize knowledge point encyclopedia, PEP edition
The following are some of the must-memorize knowledge points for the Biology elective 1 of the People's Education Version: 1. **DNA related knowledge ** - ** Dissolution **: DNA and protein have different dissolutes in different concentration of NaCl-based solutions. This feature can be used to separate DNA from impurities. DNA is not dissolved in alcohol solution, but some protein is dissolved in alcohol, which can further separate DNA and protein. - ** Resistance to acids, high temperatures, and deterrents **: The protein has no effect on DNA. Most protein cannot withstand high temperatures of 60 - 80°C, while DNA will only denature above 80°C. The deterrents can disintegrate the cell membrane, but it does not affect DNA. - ** Identification **: Under the conditions of boiling water bath, DNA will be dyed blue when it comes into contact with diamines. diamines can be used as a reagent for DNA identification. - **DNA extraction and identification of experimental materials **: Biological materials containing DNA are acceptable, but biological tissues with relatively high DNA content are better. - ** Disrupting cells to obtain the Dna-containing fluid (chicken blood cells and plant cells as examples)** - Chicken blood cells: Distilled water was added to the chicken blood cell fluid, stirred with a glass rod, and filtered to obtain the filtered fluid. Distilled water was a hypotonic liquid for chicken blood cells. A large amount of water entered the blood cells and caused them to burst. Stirring accelerated the rupture and released DNA. - Plant cells (taking onions as an example): Add the washing agent and salt to the chopped onions, stir and grind them thoroughly, and then filter them to obtain the grinding liquid. The washing agent dissolved the cell membrane, which was conducive to the release of DNA, while salt (NaCl2) was conducive to the dissolution of DNA. If the grinding was insufficient, the DNA in the nucleus would not be completely released, which would affect the results of the experiment. The filtered liquid of this step may contain impurities such as protein, glycan, and R A. - ** Removing impurities in the filtered solution **: There are three methods: one is to use the different dissolutes of DNA in different concentration of NaCl-solution; the second is to use a protein to decompose the protein but not the DNA; the third is to use the different denature temperatures of the protein and DNA. - **DNA extraction and identification procedures (onion as an example)** - Weigh 30 grams of chopped onions, add a small amount of Quartz sand to aid grinding, pour 10mL of 2-mole/L solution of NaCl3 and grind them thoroughly (onions can be treated first to reduce irritation). The purpose of grinding is to break the cells and let the DNA dissolve in the NaCl3 solution. There is no need to grind them into a porridge paste, and you can't use a whisk. - After grinding, it was filtered with a funnel and gauze to obtain the filtered liquid. - Add 20ml of 95% alcohol solution to the filtered solution (pour it slowly along the beaker wall without shaking or stirring). The upper layer of the solution will separate out a white, fibre-like viscous substance (DNA), which can be gently rolled up with a glass rod. 2. ** Traditional fermentation technology ** - ** Fruit wine making ** - ** Principle **: Yeast's anoxide-free breathing, the reaction formula is C6H12O6 → 2C2H50H +2CO2 + energy. - ** Source **: Wild yeast attached to grape skin or artificially cultivated yeast. - ** Condition **: 18 - 25 ° C, sealed, venting (CO2) at intervals. - ** Detection **: Under acidic conditions, the reaction between the alcohol and the potassium bichromate is grayish-green. - ** Fruit vinegar production ** - [Principle: Aerobic Breathing of Acetic Acid bacteria.] When O2 and sugar source were sufficient, sugar would be decomposed into vinegar; when O2 was sufficient and sugar source was insufficient, alcohol would be transformed into jumped and then into vinegar. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
