how do the following structures help in respiration in plants? (a) lenticels (b) stomata (c) root hairs
Answers
Hey mate ur answer....
Lenticel
A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants. It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues
and atmosphere through the bark, which is otherwise impermeable to gases.
Stomata
Taking in oxygen is very important because it allows your cells to do things, like make energy from the food you eat. Plants 'breathe' too, but they do it through tiny openings in leaves called stomata.Stomata open and close to allow the intake of carbon dioxide and the release of oxygen.
Root hairs.
The role of the roots is to absorb water from the soil by osmosis and dissolve mineral ions from the soil by active transport. ... the root hair cell contains lots of mitochondria, which release energy from glucose during respiration in order to provide the energy needed for active transport.
Hope this help u...
Answer:
(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.
