After a rainstorm, some precipitation flowed downhill as runoff, and some was absorbed by the ground. The roots of a plant took in some of the water that was absorbed by the ground. Which of the following statements explains what will happen to the water that was taken into the plant?

Question

A.
Gravity from the Moon will pull water vapor out of the plant's leaves and condense it in the atmosphere.
B.
Heat from the Sun will cause some of the water to transpire from the plant's leaves as water vapor.
C.
The plan't roots will release some of the water back into the soil as groundwater for other plants to use.
D.
The plant's stem will store the water until the plant dies and then the water is released as runoff.

Answer 1

The correct statement is:

B. Heat from the Sun will cause some of the water to transpire from the plant's leaves as water vapor.

Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as water vapor through tiny openings (stomata) in the leaves. This process is influenced by heat from the Sun, which helps drive the evaporation of water from the leaves.
