Question

How do the following structures help in respiration in plants?
(a) Lenticels
(b) Stomata
(c) Root hairs

Answer 1

(a) Lenticel-A lenticel is a porous tissue consisting of cells with large intracellular shapes in the periderm of secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants. It functions as a pore providing a gateway for direct exchange of gases between the internal tissues.

(b) Stomata-Plants breathe through a tiny opening in leaves called stomata.

(c) Root hairs-The role of roots is to absorb water from the soil by osmosis and dissolve mineral ions from the soil by active transport.
