Question

structure in plant that facilities gaseous exchange ​

Answer 1

Answer:

stomata

The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

Answer 2

The structure of the plant is Stomata.

• Gases can only diffuse into and out of leaves through tiny apertures called stomata on the underside of the leaf.
• These stomata can open and close in response to the demands of the plant and are the organs that allow for gas exchange in leaves.
• Mesophyll refers to the tissues of a leaf that lie among the epidermal cells and into which gases from the stomata permeate.
• Every stoma is enclosed by two guard cells that can open and close in reaction to their surroundings.
• When there is a lot of moisture, the guard cells expand with water, pushing the stoma opening to open and enabling gas exchange.
