In which part of the plant does most photosynthesis occur?

Most photosynthesis occurs in the leaves of the plant. Leaves are specifically adapted for this process; they contain a high concentration of chloroplasts, which are the organelles responsible for capturing sunlight and converting it into chemical energy. The structure of leaves, which includes a large surface area and a thin design, maximizes light absorption. Additionally, the presence of stomata, tiny openings on the leaf surface, allows for the exchange of gases (carbon dioxide entering and oxygen exiting), which is crucial for photosynthesis. In contrast, roots primarily absorb water and minerals, stems serve to support and transport substances, and flowers are involved in reproduction rather than photosynthesis.
