Which organelle in a plant cell is mainly responsible for photosynthesis?
Chloroplast
Chloroplasts are plastids that contain the green pigment chlorophyll, arranged on stacks of membranes called grana, with the stroma around them. Chlorophyll absorbs light energy, which is used to make glucose from carbon dioxide and water.
So the chloroplast is the site of photosynthesis in a plant cell, which is why it is found mostly in the cells of green leaves.
Mitochondria carry out aerobic respiration and release energy as ATP, ribosomes are the sites of protein synthesis, and the nucleus contains the genetic material and controls the activities of the cell. None of them traps light to make food.
Hence, Chloroplast.
