Which of these correctly explains the difference between the processes of photosynthesis and respiration?

Option C) The Calvin cycle takes place only in the chloroplast is the correct.

The Calvin cycle or C3 cycle is also known as dark reaction. It is a light-independent process of photosynthesis that take place in the stroma of the chloroplast, where the enzymes are present for the reactions of this cycle. In the Calvin Cycle, carbon dioxide gas is reduced to sugar using assimilatory power (ATP and NADPH) produced during light reactions.

The Krebs cycle occurs in mitochondria and glycolysis takes place in cytoplasm of the cell. These two processes are the part of cellular respiration.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
