On average there are _______ or more thylakoid per granum?
Correct answer: B. 50
- A. 60

Explanation
A granum is a stack of thylakoid membranes in a chloroplast, and many textbook descriptions give an average of about 50 or more thylakoids per granum. Students may choose 40 because granum size varies, but the commonly tested approximate value here is 50 or more.
