Question

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?

Answer 1

• In plants, the water is absorbed by the plants from the soil through the roots. Xylem tissue of the roots, stems, and leaves are interconnected to form a continuous system of water-conducting channels.
• During the day, when stomata are open, the transpiration pull becomes the major driving force for water movement in the xylem.
• The evaporation of water molecules from the stomata creates a suction, which pulls water from the roots xylem cells to the stem and then to the leaves.
