Organelles found mostly in plants cells (and some protists) which help convert solar energy into chemical energy.

They are composed of an aqueous fluid known as stroma, thylakoid disks that are stacked to form grana, and light-absorbing pigments including chlorophyll and carotenoids.

Microscopic, ellipsoidal organelle in a green plant cell. It is the site ofphotosynthesis. It is distinguished by its green colour, caused by the presence of chlorophyll. It contains disk-shaped structures called thylakoids that make possible the formation of ATP, an energy-rich storage compound.
The word chloroplast is derived from the Greek words chloros, which means green, and plastis, which means "the one who forms".

chloroplast is the one who conducts photosynthesis (use sun to produce sugar)
Chloroplasts are small green dots found in plant cells, that make the plant green and also responsible about photosynthesis
(in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
