Question

which of the following statements best supports why plants undergo cellular respiration? a because it is the opposite of photosynthesis and must be carried out to retain the balance of the carbon cycle b because plants must maintain a certain amount of carbon within them for overall cell function c to maintain cell function, especially as it pertains to the organelle, chloroplasts d to obtain energy from the glucose they created during photosynthesis

Explanation:

Cellular respiration in plants is the process of breaking down glucose to release energy in the form of ATP. Plants produce glucose during photosynthesis and then use cellular respiration to extract energy from that glucose for various metabolic processes. Option A is about the carbon - cycle balance rather than the direct reason for plants to respire. Option B is not the main reason as maintaining carbon amount is not the key driver of respiration. Option C is incorrect as respiration is not mainly related to maintaining chloroplast function.

Answer:

D. to obtain energy from the glucose they created during photosynthesis
