Final answer:
The structure found in only plant cells that functions in photosynthesis is the chloroplast. Chloroplasts contain chlorophyll and are responsible for converting light energy into chemical energy in the form of glucose and oxygen.
Step-by-step explanation:
The structure found in only plant cells that functions in the process of photosynthesis is the chloroplast.
Chloroplasts are double-membraned organelles that contain chlorophyll, the pigment responsible for capturing light energy during photosynthesis. This process takes place in the chloroplasts, specifically in the thylakoid membranes where the photosystems are located.
Inside the chloroplasts, the light energy is converted into chemical energy, which is used to synthesize glucose and oxygen from carbon dioxide and water through the series of reactions known as the Calvin cycle.
