The photosynthesis of green plants is of great significance to humanity.

Whether for the plants themselves or for humans, plant photosynthesis plays an important role. Next, let us take a look together 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 certain bacteria use chlorophyll, under the illumination of visible light, to convert carbon dioxide and water into organic matter and release oxygen. For almost all organisms in the biological world, this process is the key to their survival, and photosynthesis is indispensable to the carbon-oxygen cycle on Earth.

Conditions affecting photosynthesis

Light: Photosynthesis is a photobiochemical reaction, so the photosynthetic rate accelerates as light intensity increases. But after exceeding a certain range, the increase in photosynthetic rate slows down until it no longer increases. The photosynthetic rate can be expressed by the amount of CO2 absorbed; the greater the amount of CO2 absorbed, the faster the photosynthetic rate.

Carbon dioxide: CO2 is the raw material for photosynthesis in green plants, and its concentration affects the progress of the dark reaction of photosynthesis. Within a certain range, increasing the CO2 concentration can increase the rate of photosynthesis. After the CO2 concentration reaches a certain value, the photosynthetic rate no longer increases, because the products of the light reaction are limited.

Temperature: The chemical reactions in photosynthesis are all carried out under the catalytic action of enzymes, and temperature directly affects enzyme activity. The relationship between temperature and photosynthetic rate is just like the relationship between temperature and enzymes: there is an optimum temperature.

Mineral elements: Mineral elements directly or indirectly affect photosynthesis. For example, N is an element that constitutes chlorophyll, enzymes, and ATP compounds, P is an element that constitutes ATP, and Mg is an element that constitutes chlorophyll.

Water: Water is not only one of the raw materials for photosynthesis, but can also affect the opening and closing of leaf stomata, indirectly affecting CO2 absorption. A lack of water will cause the photosynthetic rate to decline.

The photosynthesis of green plants

Photosynthesis provides the source of matter and the source of energy for the survival of almost all organisms, including humans. Therefore, photosynthesis is of very great significance to humans and the entire biological world, and is called the most important chemical reaction on Earth. The significance of photosynthesis can be summarized in the following aspects:

1. Producing organic matter. It is estimated that green plants on Earth produce about four to five thousand hundred million tons of organic matter each year. Therefore, people compare the green plants on Earth to a huge "green factory."

2. Converting and storing solar energy. Green plants convert solar energy into chemical energy through photosynthesis and store it in the organic matter produced by photosynthesis. Almost all organisms on Earth directly or indirectly use this energy as the energy source for their life activities. The energy contained in fuels such as coal, oil, and natural gas was, in the final analysis, stored by ancient green plants through photosynthesis.

3. Keeping the content of oxygen and carbon dioxide in the atmosphere relatively stable. It is estimated that the oxygen consumed by all organisms worldwide through respiration and the oxygen consumed by burning various fuels average 10000 t/s. At this rate of oxygen consumption, the oxygen in the atmosphere would be used up in only about three thousand years. However, this situation has not occurred. This is because green plants are widely distributed across the Earth and continuously absorb carbon dioxide and release oxygen through photosynthesis, thereby keeping the content of oxygen and carbon dioxide in the atmosphere relatively stable.

4. Playing an important role in biological evolution. Before green plants appeared, there was no oxygen in Earth's atmosphere. Only after green plants appeared on Earth and gradually gained dominance about 2 billion to 3 billion years ago did Earth's atmosphere gradually come to contain oxygen, thereby enabling other organisms on Earth that carry out aerobic respiration to arise and develop.

What are the feng shui plants for courtyards?

1. Palm: Also known as the palm tree, it has ornamental value, and its trunk can also be used for courtyard pillars and the like. The palm fiber can be used as medicine, with the function of drying dampness and stopping bleeding, mainly treating vomiting of blood and collapse and other symptoms. In feng shui, it has the effect of generating wealth and attracting wealth.

2. Orange tree: Also the tangerine tree. "Orange" is homophonous with "auspicious," symbolizing good fortune. Its fruit colors are red and yellow and full of festivity. Potted citrus is an important decoration for families during the Spring Festival, and orange leaves also have the function of soothing the liver and relieving depression, and can bring joy to the home.

3. Cherry blossom: "Cherry" is homophonous with "win," implying the bringing of wealth and opportunity. Cherry blossoms have great ornamental value. When the flowers bloom, they are gorgeous and romantic, bright and abundant, symbolizing wealth and abundant blessings; when the flowers fall, they flutter profusely, clean and unstained, symbolizing freedom and transcendence. They present a kind of open-minded spirit toward life and are very profound. In addition, the roots and leaves of cherry blossoms can be used as medicine, and the flowers can be purified into skincare essential oil, so they have many uses.

4. Bamboo: Su Dongpo said: One would rather eat without meat than live without bamboo. Bamboo is a symbol of elegance and freedom from vulgarity, fears no wind from the east, south, west, or north, and can even become a feng shui protective forest for the home.

5. Toon tree: The Zhuangzi Xiaoyao Poem says: In ancient times there was a great toon tree, with eight thousand years as its autumn. Therefore, the toon tree is an omen of longevity. Later generations also used it as another name for one's father. In feng shui, it has the effect of protecting the home and praying for longevity.

6. Pagoda tree: The pagoda tree has hard wood and can be used as a landscaping tree, street tree, and so on. In feng shui, it is considered to represent official salary. In ancient courts, three pagoda trees and nine thorn trees were planted. Ministers and high officials sat beneath them, and those facing the three pagoda trees were the three highest officials. Therefore, among planted trees, the pagoda tree has the highest grade, and has authority in guarding the house.

7. Osmanthus tree: Legend has it that there is an osmanthus tree in the moon. Osmanthus is also called muxi. Osmanthus can be used as medicine, with the function of dispelling wind pathogens and harmonizing. Song Zhiwen's verse says: Osmanthus falls in the moon, heavenly fragrance drifts beyond the clouds. Osmanthus symbolizes nobility and purity. In summer, osmanthus is fragrant in all directions and is a natural air freshener.

8. Plum: The plum tree has strong adaptability to soil. Its flowers bloom with five petals, representing purity and wealth. Its five petals carry the meaning of the plum blossoming five blessings, and have the effect of enhancing the good fortune of the home.
