Water is used by the leaves of the plants for photosynthesis but rather than watering the leaves, we water the plant through the soil. How does this water reach the leaves of the plant?
Roots Absorption

Answer
- In plants, water is absorbed from the soil through the roots. The xylem tissue present in roots, stems and leaves forms a continuous system of water-conducting channels that allows the upward movement of water.
- During the daytime, when stomata on the leaves are open, transpiration (loss of water in the form of vapour) takes place which creates a transpiration pull, which becomes the major driving force for the upward movement of water through the xylem.
- As water evaporates from the stomata, it creates a suction pressure that pulls water upward from the roots to the stem and finally to the leaves, where it is used in photosynthesis.
