Question

During the water cycle, which part of the plant is involved in the process of evaporation?
1.  Leaves
2.  Branches
3.  Roots
4.  Stem

Answer 1

Correct Answer - Option 1 :  Leaves

The correct answer is Leaves.

• During the water cycle, leaves are involved in the process of evaporation.
• Plants absorb water from the soil. The water moves from the roots through the stems to the leaves.
• Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air.
• This process of evaporation through plant leaves is called transpiration. 

• Evaporation is the process by which water changes from a liquid to a gas or vapor.
• Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. 
• A very small amount of water vapor enters the atmosphere through sublimation, the process by which water changes from a solid (ice or snow) to a gas, by passing the liquid phase.
