Question

How does woody stem transpire?

Answer 1

Transpiration:

• The process involving the liberation of water molecules from the plants in the external environments through certain openings is known as transpiration.

Lenticular Transpiration:

• The woody stems contain some raised pores known as lenticels.
• The lenticels allow the movement of water molecules from the cortical cells of the plant into the atmosphere resulting in transpiration. It is known as lenticular transpiration.

Therefore, the woody stems transpire with the help of lenticels.
