A.chloroplast
B.grana
C.stomata
D.thylakoid

Answer 1

Stomata it has bean like structure which closes and opens.
So correct answer is stomata

Answer 2

Answer: C. Stomata

Explanation:

Chloroplast is present in the leaf; by this the photosynthesis of the plant happens. So, no gas exchanges occur by the help of chloroplast.

Grana is the granules which are present in the chloroplast which is also helps in the process of the photosynthesis. So, plant cannot take any gas by the use of these grana.

Stomata are present on the stem and the leaves of the plants. These are tiny pores in the skins of the stem or the leaves. Plants take carbon dioxide through these stomata and gives oxygen through these pores. So this is the correct answer.

Thylakoid is also a structure within the chloroplast.
