Question

1. what is the role of plants in the water cycle?

Explanation:

Plants drive two key parts of the water cycle: first, they absorb groundwater via their roots, moving it to leaves. Second, through transpiration, they release water vapor from leaf stomata into the atmosphere, which then condenses into clouds. They also intercept precipitation on foliage, slowing runoff and allowing more water to infiltrate soil to recharge groundwater.

Answer:

Plants play three core roles in the water cycle:

1. Transpiration: They absorb groundwater through roots, transport it to leaves, and release water vapor into the atmosphere via leaf stomata, adding moisture that forms clouds and precipitation.
2. Water Absorption & Retention: They take in soil water, reducing surface runoff and allowing more water to infiltrate and replenish groundwater reserves.
3. Interception: Foliage and stems catch falling precipitation, slowing its movement to the ground, which increases infiltration and reduces erosion.
