Background
Transpiration is the process by which water on the surface of a plant (mainly leaves) is released into the air in the form of water vapor. Transpiration is different from evaporation in physics, the transpiration effect is influenced by the external environment and also can be regulated and controlled by plants, so the transpiration effect is more complicated than the evaporation effect, the transpiration effect is irrelevant to the size of the plants, and even if seedlings still can transpire, the process that moisture is dissipated outwards from the overground part of the plants in a water vapor state is called the transpiration effect. There are two ways of losing water from the plant body to the atmosphere, one is to escape the body in a liquid state, e.g. spitting water; another way is to escape the gas phase from the body, i.e. transpiration, which is the main way a plant loses water, transpiration occurs in three places, stomata: the air holes are distributed on the leaves and the green stems, water is evaporated from plant cells, water vapor diffuses to the outside through the air holes, and about 90% of water is dissipated through the air holes in dense plants; horny layer: water evaporates at the cell wall of the epidermal cell and passes through the stratum corneum covering the leaves and green stem, and depending on the thickness of the stratum corneum, about 10% of the water is lost through this pathway; skin hole: even though the water vapor is dissipated through the bark holes on the wood stems, the water vapor is the main dissipation path of the water of the trees after leaves fall, the water vapor has small water dissipation proportion under the general condition, and the plants can be prevented from being burnt by the transpiration in the unusual hot weather, but the plants suitable for the hot weather have other more effective heat-resistant means.
