Question

Assertion: C4-plants photosynthesize more efficiently than C3-Plants.

Answer 1

It is true that C4 plants photosyntesize more efficiently than C3 plants.

C3 plants have higher photorespiration rate which makes them less efficient in the process of photosynthesis.

Also C3 plants can only photosynthesize when stomatal pores are open but C4 plants can photosynthesize even with closed stomata.
