Answer 1

The term granum refers to a stack of coin-shaped thylakoids in the chloroplasts of plant cells. There can be as few as 2 or as many as 100 thylakoids in grana, or groups of granum, and between 40 and 60 grana in a plant cell. Thylakoids are membranous pockets or structures found inside the chloroplasts of plant cells.
