Which statement describes thylakoids?

glucose is formed here.

Correct

D) Photosystems I and II are found here :)

The correct answer is photosystem I and II function here.

Explanation:

Thylakoids are pouch-like membranous structure present in the chloroplasts and in the members of blue green algae. Chlorophyll pigments are located on the thylakoids. Chlorophylls are arranged in groups called photosystems. Photosystem I and photosystem II are the two photosystems which are embedded in the thylakoid membrane. These photosystems are the site of the light-dependent photosynthetic reactions. The chlorophylls absorb light and use it for the synthesis of ATP and reduced coenzymes NADPH.
