Question

a) Translocation
b) Transpiration
c) Photosynthesis
d) Osmosis

Answer 1

Transpiration is the process by which water is pulled up through the xylem columns of plants as it evaporates out of the leaves.

Step-by-step explanation:

Transpiration is the process by which water is pulled up through the xylem columns of plants as it evaporates out of the leaves. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf-atmosphere interface, creating negative pressure (tension) which pulls water up from the roots. This process is known as the cohesion-tension theory of sap ascent.
