a cell in the leaf of a green plant performs, but photosynthesis and cellular respiration often at the same time. Which statement best describes how these processes are related to each other?

Answer 1

Photosynthesis and cellular respiration are interconnected processes that occur in plants, albeit in different organelles and with distinct functions. The statement that best describes their relationship is:

"Photosynthesis captures light energy to convert carbon dioxide and water into glucose and oxygen, while cellular respiration uses the glucose produced in photosynthesis along with oxygen to generate ATP, carbon dioxide, and water, thereby providing energy for the plant's cellular activities."

In essence, the products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and the products of cellular respiration (carbon dioxide and water) are the reactants for photosynthesis, forming a cyclic relationship that sustains the plant's energy needs.
