Question

To control the movement of gases, land plants developed
A) stomata.
B) a cuticle.
C) flowers.
D) vascular tissue.
E) lignin.

Accepted Answer

Stomata are tiny openings found mainly on the leaves and stems of land plants that control the exchange of gases (such as CO2 and O2) between the plant and the environment. The opening and closing of the stomata is regulated by the plant, and it allows the plant to adjust to changing environmental conditions such as light, temperature, and water availability.
