Answer 1

Correct option is (c) 200 – 250

The explanation is: In a photosynthetic unit, 200 – 250 number of chlorophylls are present. They are embedded in the thylakoids of chloroplast. It differs for different plant species as in algae, it is only 100 in number. The number of chlorophylls is based on their requirement and function.
