The statement that is NOT true about the processes of photosynthesis and cellular respiration is:

B. Carbon dioxide is needed for cellular respiration to occur.

This statement is inaccurate because cellular respiration primarily uses oxygen to produce energy from glucose and produces carbon dioxide as a waste product. While organisms involved in photosynthesis (like plants) do require carbon dioxide to produce glucose and oxygen, it is not needed for the process of cellular respiration itself.
