The site of photosynthesis in a plant cell is primarily the chloroplast.
Chloroplasts are specialized organelles found in the cells of green plants and algae. They contain chlorophyll, the green pigment that captures light energy from the sun. During photosynthesis, light energy is used to convert carbon dioxide and water into glucose and oxygen. This process is essential for producing the energy that fuels plant growth and sustains life on Earth. The structure of the chloroplast, with its thylakoid membranes where light reactions occur, and the stroma where the Calvin cycle takes place, plays a crucial role in the overall efficiency of photosynthesis.
