Transpiration helps in which transport in plants?
Answer and explanation
Correct answer: Upward movement of water and minerals
The governing concept is transpiration pull in plant transport. When water evaporates from leaf surfaces through stomata, it creates negative pressure in the continuous water column inside xylem. Cohesion between water molecules helps transmit this pull downward, assisting the upward movement of water and dissolved minerals from roots to leaves. Therefore option A is correct. The other options refer to animal digestion, circulation or excretion, not transport through plant xylem.
