What is transpiration of plant leaves? What does it do?

The process by which water is lost outward from the aboveground parts of the plant body in a state of water vapor is called transpiration. It is divided into keratinous transpiration, cutaneous transpiration, and stomatal transpiration according to different pathways of water loss. Generally, picopore transpiration is the main effect.

The transpiration of plants can promote the absorption and transportation of water and mineral elements in the plant body, promote the transportation of organic matter in the plant body, reduce the temperature of the plant body and leaves, reduce the damage of high temperature and strong light to the plant body, and is conducive to the normal progress of photosynthesis. When cultivating plants, if the seedlings are planted in batches, the 1 3 leaves must generally be removed to reduce transpiration and facilitate survival.

The transpiration of plants is to evaporate the water in the body through the stomata on the leaf surface, and the effect is to drive the flow of water in the plant and promote the absorption of water by the roots.

It was originally a leaf, and when it first met humans, it was used as a remedy for detoxification, and through the hands of the Chinese, it turned into a kind of fu (fù) yu belief. According to the way Chinese characters are written, tea is a person between plants and trees. For more knowledge points**, WeChat pays attention to related disciplines*** "Biology Master".

The removal of water from the leaves through the stomata on the back of the leaves is transpiration, which can provide power for the plant to transport water and regulate the temperature. This is the transpiration of the leaves.

Transpiration is not only affected by external environmental conditions, but also regulated and controlled by the plant itself, so it is a complex physiological process. The main processes are: moisture in the soil Root hairs Root ducts Stem ducts Leaf ducts Stomata Atmosphere, when plants are young, all surfaces exposed to air can transpire.

Transpiration is the main driving force for plants to absorb and transport water, and without transpiration, the water absorption process caused by transpiration pull cannot occur. Transpiration also helps transport inorganic salts. Transpiration lowers the temperature of the leaves so that they don't get burned.

Transpiration also favors in vivo and in vivo gas exchange.

Transpiration is one of the main driving forces for water absorption and transportation of plants, especially for tall plants, if there is no transpiration, the water absorption process caused by transpiration pull cannot be produced, and the higher part of the plant will not be able to obtain water, so it is particularly important for tall trees.

Since inorganic salts must be dissolved in water in order to be absorbed and run in the body, since transpiration is the driving force for water absorption and flow, minerals will also be inhaled and distributed to all parts of the plant body with the absorption and flow of water, helping plants to transport these two types of substances.

Transpiration can reduce the temperature of the leaves, when the sun shines on the leaves, most of the energy will be converted into heat, if the leaves do not have the function of cooling, the temperature of the leaves will be too high, and the leaves will be burned. In the process of transpiration, the water becomes water vapor because it needs to absorb heat energy.

Transpiration favors in vivo and in vivo gas exchange. When the leaves are photosynthesizing, the stomata will open, and the open stomata will become a channel for carbon dioxide, oxygen, and water vapor. If the stomata are closed, it will also affect the physiological processes such as photosynthesis and respiration of plants.

Summary. Hello, 1The transpiration pull produced by transpiration is the main driving force for plants to passively absorb and transport water, which is especially important for tall trees.

2.Transpiration promotes the transport of substances in xylem sap. Minerals, salts in the soil and substances synthesized by the roots can be transported and distributed to all parts of the plant body with water absorption and collection.

3.Transpiration lowers the temperature of the plant. This is because water has a high heat of vaporization, which can dissipate a large amount of radiant heat during transpiration.

4.The normal process of transpiration is conducive to the assimilation of CO2, because when the leaf undergoes transpiration, the stomata are open, and the open stomata become the channel for CO2 to enter the leaf. Hope mine can help you.
