Question

A cell in the leaf of a green plant performs both photosynthesis and cellular respiration, often at the same time. Which statement best describes how these processes are related to each other?
A.Products of one process are used as some of the reactants for the other processes.

B.Both processes produce carbon dioxide.

C.Both processes require energy directly from the Sun.

D.Thermal energy from one process is used as the energy source for the other process.

Answer 1

The right answer is A.

Plant species are particular in their ability to produce oxygen and carbohydrates through photosynthesis. The plant, just like the animals also needs to breathe so that these cells survive, so it is forced to take some of the oxygen and carbohydrate produced by photosynthesis to operate these cells through cellular respiration.
