Question

Name the respiratory structures in leaves of plant

Answer 1

Answer:

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.

Explanation:

All parts of the plant respire, the leaves, the stem, the roots and even the flowers. The parts above the soil get their oxygen directly from the air through pores. The pores in the leaves are called stomata (singular: stoma). The pores in the branches of trees are called lenticels..

Leaves. The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

Answer 2

 The respiratory structure in leaves of plant is stomata present in epidermis.

Explanation:

• Singular of stomata is stoma (greek, stoma=mouth )  , a typical stoma is microscopic and usually consist of two kidneys shaped guard cells surrounding a pore. All the gaseous exchange occurs through this pore called stomata in leaves.

• The guard cells are rapidly affected even by a small change in turgor which is responsible for opening and closing of stomata .

• The stomatal pore is generally elliptical in surface view .the dimension of stomatal pore varies from species to species .
