Question

Gaseous exchange in plants occur through
A. Chloroplast
B. Stomata
C. Waxy cuticle
D. Bulliform cell

Answer 1

Hint: Green plants use carbon dioxide as a means of depositing oxygen to carry out the process of photosynthesis. They need oxygen as a way of disposing of carbon dioxide when they are breathing.

Complete answer:
Stomata are described as the tiny openings or pores that are needed for gaseous exchange within plant tissues. These are normally only in plant leaves, but in some stems, they may also be present. The stomata are surrounded by specialized cells or guard cells that promote the opening and closing of the pores of the stomata. These pores allow gaseous exchange between the plants.
-Chloroplasts are green-colored plastids that act in eukaryotic photoautotrophs as the site of photosynthesis. They are often found in mesophyll cells in plant leaves along their walls to promote the diffusion of gases and to receive the optimum amount of incident light.
-The foliage of all plant species is covered by a waxy coating known as the cuticle. The cuticle decreases the rate of loss of water from the surface of the leaf. On the leaf surface, other leaves can have tiny hairs (trichomes).
-Bulliform cells can be present in wheat leaves. Bulliform cells are bubble-shaped cells that are present on the upper surface of the leaves of many monocots in groups near the mid-vein section. The presence of these cells allows the cell to withstand conditions of stress. These are cells that are big, empty, and transparent and can store water.

Hence, the correct answer is option A-Stomata.

Note: The net exchange of gases from the surface of the leaf depends on the strength of the light that occurs on it. Most stomata are present in the form of pores on the underside of the leaf and aid in the transport of water.
