Final answer:
Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells and involves light-dependent reactions and light-independent reactions.
Step-by-step explanation:
Photosynthesis is the process by which plants capture light energy from the sun and convert it into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells, specifically in the thylakoid membranes. The light-dependent reactions, which take place in the thylakoid membranes, capture energy from sunlight and convert it into chemical energy in the form of ATP and NADPH. These molecules are then used in the light-independent reactions, also known as the Calvin cycle, to synthesize glucose. The overall purpose of photosynthesis is to provide plants with the energy they need to grow and survive.
