Question

the process by which plants evaporate water is called dash​

Answer 1

Transpiration is the process by which plants evaporate water

• It occurs  is process of releasing the water from stomata present in leaves on plants.
• when the environment is hot then the water absoorbed in the roots of plants gets released from stomata

Answer 2

Answer:

Transpiration

Explanation:

Transpiration is a process that involves the loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is 'pulled' into the leaves.

Transpiration provides evaporative cooling, forming a major component of the leaf energy balance. Transpiration also provides the driving force for the transport of water and nutrients from roots to shoots.

Steps of transpiration

• Water is passively transported into the roots and then into the xylem.
• The forces of cohesion and adhesion cause the water molecules to form a column in the xylem.
• Water moves from the xylem into the mesophyll cells evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Leaves contain a very large number of stomata for gaseous exchange and there is little resistance to the movement of water vapour through these pores.

Moreover, the leaves have a large surface area. The greater the surface area, the greater will be the loss of water by transpiration.
