Concept:The release of water vapour from plant leaves into the atmosphere is known as transpiration.
Explanation:In the water cycle, plants absorb water (
H2O) from the soil through their roots.
Excess water moves upward and escapes as vapour through tiny pores called stomata on the leaves.
In the diagram, the arrow directed from the plant towards the atmosphere represents this vapour loss.
This is a biological process carried out by plants.
Condensation and evaporation are physical processes of the water cycle that do not involve plants.
Respiration mainly releases carbon dioxide, not water vapour.
Therefore, the process shown by the arrow from the plant is transpiration.
Answer:A. transpiration
