Which of the following is correct for the given figure ?

Options

A. The part labelled 'b' is called intergranal thylakoid.
B. The part labelled 'c' is called granum.
C. The part labelled 'a' is the site of dark reaction.
D. The parts labelled 'a', 'b' and 'c', all possess photosynthetic pigments such as chlorophyll.

Answer

C

Explanation

The given figure is of chloroplast. The part labelled .a. is stroma. The part labelled .b. is called grana where light reaction of photosynthesis takes place. The part labelled .c. is intergranal thylakoid. Photosynthetic pigments such as chlorophyll are present only in thylakoid membranes (grana + intergranal thylakoids) and not in stroma or non-granal thylakoids.
