Question

Name two gaseous exchange structures in higher plants

Answer 1

Answer:

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.

Gases are exchanged via leaf structures called stomata. Their movement into and out of the plant is by diffusion

Opening stomata.

Closing stomata.

Density of stomata.
