Question

How many thylakoids are present in each granum in chloroplast?

• A. 20 to 50
• B. 100 - 200
• C. 10 to 100
• D. 5 - 10

Answer 1

The correct option is C

10 to 100

A thylakoid refers to the membrane-bound internal compartment within the chloroplasts of a plant cell and cyanobacteria.

It is a site for light-dependent reactions of photosynthesis. It is made up of a thylakoid membrane which surrounds the thylakoid lumen.

A stack of thylakoid disk is organized to form grana.There are about 10 to 100 thylakoids within a granum and about 40- 60 grana in a plant cell. So, the correct answer is '10-100'.
