15. When there is light, plants do which of the following biological
processes?

Plants do both photosynthesis and cellular respiration.

All cells do cellular respiration even without light.

Honestly, photosynthesis alone would be right since the teacher didnt  state the questions correctly. But you should choose both cause in the light it does both.
