Answer 1

Stomata, lenticels and root hairs all perform the function of gaseous exchange in plants.

Stomata are the tiny pores present on the surface of leaves. Their opening is regulated by guard cells.

Lenticels are tiny pores present on stem which are always open.

Root hairs are cellular outgrowths that arise from the cells of root surfaces.
