Question

Explain how the internal structure of leaves results in the loss of large quantities of water in
transpiration.

Answer 1

Answer:

Transpiration is the loss of water from the plant through evaporation at the leaf surface. ... At night, when stomata shut and transpiration stops, the water is held in the stem and leaf by the adhesion of water to the cell walls of the xylem vessels and tracheids, and the cohesion of water molecules to each other.

Answer 2

The process of evaporating the water from the surfaces of the spongy alike mesophyll cells, which are available in leaves, along with the loss of water by the way  the way of stomata is called transpiration.

Explanation:

• Transpiration produces tension or pulls from the water available in the xylem vessels by the way of leaves.
• Water molecules are having tendency of being cohesive hence water is pulled with the plant.
• The process of losing the water from the plant by the evaporation from on the leaf's upper area is called transpiration.
• The key source of the water movement in the xylem is Transpiration.
• The evaporation of water is the reason of the transpiration on the leaf surface, it creates negative pressure.

The wider the leaf area, the higher would be the rate of transpiration because wide leaves tend to have more stomata.
