Question

Why transpiration is important in plant

Answer 1

The importance of transpiration in plants is to cool the plant and provide water and nutrients to the leaves. During transpiration, water evaporates through openings in the leaves called stomata. This creates a negative pressure inside the leaves that draws water up from the roots through the xylem. This brings both water and nutrients dissolved in the water to the leaves. As water evaporates, it takes with it heat. Like sweating in animals, this helps to keep the plant cool during a sunny day.
