Answers
Answer:
The loss of water in vapour form from the leaf into the atmosphere is called transpiration. This creates a suction which pulls water from xylem cells. Thus, transpiration helps in the upward movement of cell sap or water and minerals from roots to leaves.
Explanation:
Transpiration is the loss of water from the leaves for cooling the plant. It helps in upward movement of food and water because when the leaves lose water from their surface, it creates a pressure which pulls water and food upwards.
Transpiration is the loss of water in the form of water vapour from the aerial parts of a plant. ... As water evaporates from the leaves, a suction force is created. This force helps to draw more water up through the stem which causes the roots to absorb more water from the soil.
