Five friends were talking about when plants carry out the processes of photosynthesis and respiration. This is what they said:

Janet:
“Photosynthesis and respiration occur both when it is light and when it is dark.”

Calvin:
“Photosynthesis occurs when it is light; respiration occurs when it is dark.”
Mike:
“Photosynthesis occurs when it is light; respiration occurs both when it is light and when it is dark.”
Turner:
“Photosynthesis occurs both when it is light and when it is dark; respiration happens at night.”
Sophie:
“Photosynthesis occurs in the light; plants don’t carry out the process of respiration.”

Whom do you agree with the most?

Based on the given statements, it is clear that Mike's statement is the most accurate and agrees with the known processes of photosynthesis and respiration. Mike stated that photosynthesis occurs when it is light, which is true as photosynthesis requires sunlight to convert light energy into chemical energy. Mike also mentioned that respiration occurs both when it is light and when it is dark, which is also correct as respiration is a continuous process that occurs in plants regardless of whether it is day or night. Therefore, Mike's statement aligns with the known facts about photosynthesis and respiration.
