DENDROLOGY

Detailed explanation-1: -Gases enter leaves through thousands of tiny pores called stomata (sing. stoma). In most plants these are found on the underside of leaves, where they’re hidden from strong sunlight and protected from dust. As well as allowing gases in and out, stomata also control water loss.

Detailed explanation-2: -Plants do not breathe, so they need to get oxygen through the stomata, the small little holes in their leaves, and also through their roots. In respiration, the oxygen is used to help metabolize and burn the sugars into energy.

Detailed explanation-3: -The leaves of plants have tiny pores on their surface which are called stomata. The exchange of gases in the leaves during respiration takes place through stomata. This happens as follows: Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process of diffusion.

Detailed explanation-4: -Plants breathe through tiny holes in their leaves called stomata. So, all living things breathe.
