Question

can photosynthesis and respiration occur at the same time

Answer 1

Plants respire all the time because their cells need energy to stay alive, but plants can only photosynthesise when they are in the light. The diagrams summarise what this means for the overall release of carbon dioxide or oxygen from plants. Remember that respiration uses oxygen and produces carbon dioxide.

Answer 2

Plants are always breathing to create energy which later is stored to create food . Therefore plants can perform photosynthesis while they are respiration he.
