Stoma.
exchange of gases respiration and photosynthesis takes place through stem of the plant, the stem is green enough to carry the property of leaves, as in normal plants.. while exchange of gases in huge tree trunks takes place through lenticels, which are present in barks of the trunks... exchange of gases-respiration and photosynthesis- takes place through stem of the plant, the stem is green enough to carry the property of leaves, as in normal plants.. while exchange of gases in huge tree trunks takes place through lenticels, which are present in barks of the trunks...

exchange of gases takes place by simple diffusion directly into each cell through the openings present in epidermis called stomata. Stomata are found on the underside of leaves. :)
During respiration the exchange of gases takes place through the walls of the alveoli. From there, the oxygen is taken by the blood to the body tissues.

Through the stomata of the leaves.
through respiration
Convection
It takes place in the leaves. The plant loses vapor through its leaves.
the bum hole The Stomata's
Plants respire through tiny openings or holes called stomata that are present on the underside of the leaves. Stomata trap air (like oxygen) and the exchange of gases takes place in side the plant cells.
They are metal (or perhaps plastic) tubes through which gases or chemicals are pumped from one place to another.
