Leaves get water through a process called transpiration. Transpiration is the process by which water is absorbed by the roots of a plant and then transported through the plant to the leaves. Once the water reaches the leaves, it evaporates through small pores called stomata on the surface of the leaves. This process creates a suction force that pulls more water up from the roots, allowing the plant to continue to absorb water and nutrients from the soil. In addition to transpiration, leaves can also absorb water directly from rain or dew that falls on their surface.

Leaves get water through a process called transpiration. Transpiration is the evaporation of water from the surface of plants, primarily through the leaves. It occurs when water evaporates from the leaves into the atmosphere, creating a negative pressure or suction that pulls water up through the plant from the roots.
Here's a step-by-step explanation of how leaves get water through transpiration:
1. Water absorption by roots: Water is absorbed by the plant's roots from the soil.
2. Transport of water through xylem: Once absorbed, water is transported upward through the plant's vascular system, specifically through specialized tissues called xylem vessels. Xylem vessels are long, hollow tubes that run from the roots to the leaves.
3. Evaporation from leaves: Water evaporates from the leaves through small pores called stomata. Stomata are tiny openings found on the surface of leaves, primarily on the underside.
4. Water loss creates suction: As water evaporates from the leaves, it creates a negative pressure or suction that pulls water up through the plant. This suction is transmitted downward through the xylem vessels, pulling water from the roots and soil.
5. Continuous water movement: The transpiration process creates a continuous stream of water movement from the roots, up through the xylem, and out through the stomata on the leaves. This water movement helps maintain the plant's hydration and provides water for essential metabolic processes.
Transpiration is a crucial process for plants as it provides a means to:
- Transport water and nutrients from the roots to the leaves.
- Cool the plant through evaporative cooling.
- Regulate leaf temperature.
- Control the opening and closing of stomata for gas exchange.
