Photosynthesis primarily occurs in the mesophyll of the leaves within flowering plants.
The Role of Leaves in Photosynthesis
Leaves are the primary sites of photosynthesis because they contain specialized structures called chloroplasts.
- Chloroplasts: These organelles are the powerhouses of photosynthesis. According to the reference, "In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts."
- Mesophyll: The mesophyll tissue within leaves is rich in chloroplasts, making it ideal for capturing sunlight and converting it into energy.
Chloroplast Structure and Function
Chloroplasts contain key components essential for photosynthesis.
- Thylakoids: These disc-shaped structures within chloroplasts contain chlorophyll.
- Chlorophyll: This pigment absorbs specific portions of the visible spectrum and captures energy from sunlight, driving the photosynthetic process. As noted in the reference, "Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll."
