Question

We need to water the soil in plants on a regular basis but it ultimately reaches the leaves of the plant. Explain how this takes place.

Answer 1

Transpiration is the process by which water flows from the earth to the leaves of plants. When plants receive water through their roots, it moves upward through specialized veins known as xylem. This movement is caused by capillary action, root pressure, and water evaporation from the leaves (transpiration pull). Water evaporates from the surface of the leaves through tiny pores known as cellular pores, creating a negative pressure that pulls additional water up from the roots. This continual flow of water transports critical nutrients from the soil to various regions of the plant and maintains the plant's structure by keeping cells dry.
