3 How plant leaves produce nutrients and release oxygen

Usually refers to green plants absorbing light energy and turning carbon dioxide.

In the process of releasing oxygen while hydrating into organic matter, green plants use solar energy, carbon dioxide and water to produce organic matter to release oxygen, which is called photosynthesis.

Transpiration, the surface of the plant body is mainly water from the leaves with water vapor.

The process of state dissipation into the atmosphere, unlike the evaporation process in physics, evapotranspiration is not only affected by external environmental conditions, but also regulated and controlled by the plant itself, which is a complex physiological process.

Respiration. The organic matter in the cell is oxidized and decomposed by a series of enzymes in stages, and the process of releasing energy at the same time, respiration is a common feature of all living cells, generally there are stomata on the back of the leaf, there is respiration, and the respiration of the leaf is to absorb carbon dioxide and discharge oxygen.

Reproduction, vegetative reproduction of plants mainly depends on roots and stems, but there are also some plants that also have a reproductive effect on leaves, for example, settling and galancho can form adventitious roots and adventitious buds at the end of leaf veins, Nivea.

and Sedum can form adventitious roots and adventitious buds at the base of the petiole, and the young fleshy leaf sheath of the tiger can also generate adventitious buds for vegetative propagation.

Absorption, the epidermal cells of plant leaves absorb the substances attached to the leaves, and foliar fertilization and foliar spraying of herbicides according to the absorption of the leaves can also absorb nutrients.

Protectively, the leaves of plants can protect fruits and stems from being destroyed by insects or other organisms.

Plant leaf cells contain chloroplasts, which can use chlorophyll to absorb sunlight energy, synthesize carbon dioxide and hydration into starch and other organic matter, and convert light energy into solar energy, which is stored in the organic matter it produces.

This process is called photosynthesis, and this role is still very important, and it can provide us humans with a lot of oxygen.

This process is called photosynthesis in plants, and it is generally formulated in biology that photosynthesis can release oxygen.

This process is called photosynthesis, and most plants have such a process, and the photosynthesis of plants can also turn inorganic matter into organic matter.

Carbon, hydrogen, and oxygen are the main components of plant organisms. Carbon is the basis for the skeleton of organic matter. Carbon, hydrogen and oxygen can form a variety of carbohydrates, such as lignin, cellulose, hemicellulose and pectin, which are important components of the cell wall, which is the backbone that supports the plant body. Carbon, hydrogen and oxygen can also constitute various active substances in plants, such as certain vitamins and plant hormones, which are necessary for normal metabolic activities in the body;

In addition, they are also components of sugars, fats, and phenolic compounds, of which sugar is the most important. Carbohydrates are the basic raw materials for the synthesis of many important organic compounds in plants, such as proteins and nucleic acids. The energy needed in plant life must be converted and released during the metabolic process of carbohydrates.

Carbohydrates not only constitute the permanent skeleton of plant gods, but also serve as food for plants to temporarily store or actively participate in the metabolism of substances in the body (including the absorption, synthesis, decomposition and transportation of various inorganic salts, etc.), and form a wide variety of substances in the mutual transformation. It can be seen that carbohydrates are the core substances of plant nutrition.

Generally, the oxygen used for the respiration of the roots of terrestrial plants is ** in the soil, so when terrestrial plants blister with water, they will drown if the roots grow between the stoves and cannot breathe. The aquatic plum plant oxygen is on its own. I don't know if you have noticed, the lotus root and lotus leaf stalks are empty, which is the oxygen channel for the roots to breathe.
