Question

How does water reach the leaves of plants?

Answer 1

Water reaches the leaves of plants through a process called transpiration. Transpiration is the process by which water is evaporated from the leaves of the plant into the atmosphere. The water travels up the stem of the plant through xylem cells, which are thin tubes that run from the roots to the leaves. This movement of water is caused by a combination of the attraction of water molecules to each other (known as cohesion) and the adhesion of water molecules to the walls of the xylem cells. As the water evaporates from the leaf surface, it creates a negative pressure in the xylem, which causes more water to be drawn up from the roots to replace what has been lost. This continuous cycle of water movement helps to keep the plant hydrated and enables it to carry out photosynthesis, a process in which sunlight is converted into energy.

Answer 2

Water reaches the leaves of plants through a process called transpiration. It starts at the roots, where water is absorbed from the soil, then travels up through the stems and into the leaves via the xylem vessels.

Answer 3

Water is absorbed by the roots of plants and transported upwards through the xylem tissue. Transpiration, the loss of water vapor from the leaves, creates a negative pressure that pulls water up through the xylem to the leaves, where it is used in photosynthesis and other processes.
