Plastids are unique and discrete cytoplasmic organelles found in the cells of most of the plants and certain unicellular organisms particularly protozoa, but not in the cells of higher animals. Although Comparethi (1791) noticed the presence of green granules and Sacks (1865) also observed special bodies in the plant cells yet the term plastid was first used by A.F.W. Schimper in 1883.

Plastids are coloured or colourless organelles most often occurring as spherical or disc-like bodies in free state in the cytoplasm of the eukaryotic plant cells. In fungi, bacteria and blue-green algae plastids are lacking.

The size of the plastids varies from species to species. But the size remains constant for a given cell type. In higher plants, it is 4-5microns in length and 1-3microns in thickness.
