The importance of photosynthesis of green plants to people

Plant photosynthesis plays an important role not only for plants, but also for human beings. next, let's take a look at the importance of plant photosynthesis.

Photosynthesis can be divided into oxygen-producing photosynthesis and non-oxygen-producing photosynthesis. It is a biochemical process in which green plants and some bacteria use chlorophyll to convert carbon dioxide and water into organic matter and release oxygen under the irradiation of visible light. For almost all living things in the biological world, this process is the key to their survival, and photosynthesis is essential to the carbon-oxygen cycle on Earth.

Influencing conditions of photosynthesis

Light: photosynthesis is a photobiochemical reaction, so the photosynthetic rate increases with the increase of light intensity. However, after exceeding a certain range, the increase of photosynthetic rate becomes slower until it no longer increases. The photosynthetic rate can be expressed by the absorption of CO2. The greater the absorption of CO2, the faster the photosynthetic rate.

Carbon dioxide: CO2 is the raw material of green plant photosynthesis, and its concentration affects the dark reaction of photosynthesis. Increasing the concentration of CO2 in a certain range can increase the rate of photosynthesis, and when the concentration of CO2 reaches a certain value, the rate of photosynthesis no longer increases, because the product of photoreaction is limited.

Temperature: chemical reactions in photosynthesis are carried out under the catalysis of enzymes, and temperature directly affects the activity of enzymes. The relationship between temperature and photosynthesis rate is like the relationship between temperature and enzyme, there is an optimal temperature.

Mineral elements: mineral elements directly or indirectly affect photosynthesis. For example, N is the element that makes up chlorophyll, enzyme and ATP, P is the element that makes ATP, and Mg is the element that makes up chlorophyll.

Moisture: water is not only one of the raw materials of photosynthesis, but also can affect the opening and closing of stomata in leaves, and indirectly affect the absorption of CO2. Lack of water will decrease the photosynthetic rate.

Photosynthesis of green plants

Photosynthesis provides a source of material and energy for the survival of almost all organisms, including human beings. Therefore, photosynthesis is of great significance to human beings and the whole biological world, and is called the most important chemical reaction on earth. The significance of photosynthesis can be summarized as follows:

1. To make organic matter. It is estimated that green plants on the earth produce about 400 billion to 500 billion tons of organic matter every year. Therefore, people compare the green plants on the earth to a huge "green factory".

two。 Convert and store solar energy. Green plants convert solar energy into chemical energy through photosynthesis and store it in organic matter produced by photosynthesis. Almost all living things on earth use these energies directly or indirectly as energy sources for life activities. In the final analysis, the energy contained in coal, oil, natural gas and other fuels is stored by ancient green plants through photosynthesis.

3. Make the content of oxygen and carbon dioxide in the atmosphere relatively stable. It is estimated that the average amount of oxygen consumed by all organisms in the world through respiration and by burning various fuels is 10000t/s. At this rate of oxygen consumption, the oxygen in the atmosphere will run out in about three thousand years. However, this did not happen. This is because green plants are widely distributed on the earth, constantly absorbing carbon dioxide and releasing oxygen through photosynthesis, thus keeping the content of oxygen and carbon dioxide in the atmosphere relatively stable.

4. It plays an important role in the evolution of organisms. Before the emergence of green plants, there was no oxygen in the earth's atmosphere. It was only after green plants appeared and gradually dominated the earth 2 billion-3 billion years ago that oxygen was gradually contained in the earth's atmosphere, thus enabling the occurrence and development of other organisms that breathe aerobically on the earth.

What are the geomantic plants in the courtyard?

1. Palm: also known as palm tree, which not only has ornamental value, but also can be used as a courtyard post. Brown hair can be used as medicine, and its function is to collect dampness and stop bleeding, treat hematemesis and collapse, and has the function of generating money and attracting money in fengshui.

2. Orange tree: and orange tree, orange and auspicious homophonic, symbolizing auspiciousness, fruit color is red, yellow and full of festive, potted oranges are important furnishings for people's families during the Spring Festival, and orange leaves have the function of soothing the liver and relieving depression, which can bring joy to the family.

3. Cherry blossoms: "Sakura" and "win" are homophonic, implying wealth and opportunity. The ornamental value of cherry blossoms is great. When the cherry blossoms bloom, they are gorgeous and romantic, bright and varied, symbolizing wealth and wealth; when the flowers fall, they are clean and unstained, symbolizing free and easy detachment. Present a kind of open-minded boldness of life, with great depth. And cherry roots, leaves can be used as medicine, flowers can extract pure skin care essential oil, many uses.

4. Bamboo: Su Dongpo Yun: it is better to eat without meat than to live without bamboo. Bamboo is a symbol of elegance and vulgarity, and it can become a fengshui shelterbelt at home.

5. Chunshu: Zhuangzi Xiaoyao Poems says: in ancient times, there were people who were eight thousand years old as autumn, so Chunshu was a sign of longevity, and later generations thought that their father's name played a role in protecting the house and Qi Shou in fengshui.

6. Sophora tree: the wood of locust tree is hard, which can be green tree, street tree, etc., which is considered to represent Lu in fengshui. The ancient court planted three locust trees and nine thorns, and the Gongqing doctor sat under them, facing the three locust trees, so the locust tree has the highest taste among the trees, and the town house is authoritative.

7. Osmanthus trees: according to legend, there are osmanthus trees in the moon, sweet-scented osmanthus, that is, sweet clover, sweet-scented osmanthus can be used as medicine, the function is to drive the wind evil, reconcile the role, Song Zhiwen ci Yun: sweet-scented osmanthus falling in the moon, Tianxiang clouds floating outside. Sweet-scented osmanthus symbolizes nobility, fragrance overflowing in summer, and is a natural air freshener.

8. Plum: the plum tree has strong adaptability to the soil. The five petals of the plum tree are noble and noble. The five petals of the plum tree have the meaning of blooming the plum and the five blessings, which can enhance the happiness of the household.

The above is the whole content of the importance that the photosynthesis of green plants brings to people. I hope this article can help you. Please continue to follow us.
