Chloroplasts are never found in animal cells, but most of the cells in the green parts of plants have them. They contain the green colouring or pigment called chlorophyll.
Chloroplasts absorbs energy from sunlight, and this energy is then used for making food for the plants by photosynthesis.
Chloroplasts often contain starch grains, which have been made by photosynthesis in plant cells.
Chlorophyll helps plants absorb energy from the Sun during photosynthesis.
