Plants produce ATP during photosynthesis, which takes place in the chloroplasts. This means that the chloroplasts are the food-producing factories of plant cells.
Whenever the mentally disturbed prisoner clawed the plaster off (chloroplast) the prison guards had to take a photo (photosynthesis) for their records.
Chloroplasts are in plant cells only.
The number of chloroplasts in a plant cell can vary from one in algae up to 100 in wheat.
