Answer:
Step-by-step explanation:
a. Photosynthesis as a whole: Photosynthesis is a process that occurs in the chloroplasts of plant cells. Chloroplasts are organelles found in plant cells that are responsible for capturing light energy and converting it into chemical energy through the process of photosynthesis.
b. Light-dependent reactions: The light-dependent reactions of photosynthesis take place in the thylakoid membrane of chloroplasts. These reactions involve the absorption of light by pigments, mainly chlorophyll, which then transfer the energy to specialized protein complexes. These protein complexes then generate ATP and NADPH, which are used in the next stage of photosynthesis.
c. Calvin cycle: The Calvin cycle, also known as the dark reactions, take place in the stroma of chloroplasts. The stroma is the fluid-filled area outside the thylakoid membrane. The Calvin cycle is where the chemical energy generated during the light-dependent reactions is used to fix carbon dioxide into glucose and other sugars, using the energy stored in the ATP and NADPH molecules.
In summary, photosynthesis, the process that allows plants to convert light energy into chemical energy, occurs in the chloroplasts of plant cells. The light-dependent reactions take place in the thylakoid membrane and the Calvin cycle takes place in the stroma of the chloroplasts.
