Question

What is transpiration? How does it help the plants?

Answer 1

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.
Transpiration results in transpiration pull which thereby increase the rate of absorption of water along with minerals from the soil through roots.*Transpiration helps in transportation of absorbed minerals to all the parts of the plant. *Transpiration provides water for the process of photosynthesis.*Transpiration helps in cooling the structures of the plant when exposed to hot sunlight. *Transpiration helps the cells to maintain their turgidity. *Excess water is removed from the cells of the plant to prevent plant decay. *Osmotic balance of the cell is maintained by the process of transpiration. *Transpiration helps in the distribution of dissolved substances to all parts of the plant. *Transpiration is also helpful in maintaining balance in the environment by protecting trees and thereby forests.

Answer 2

Transpiration is process by which plant release water through stomata.
It help plant by realing extra water from plant body.
