plastid
n 1: any of various small particles in the cytoplasm of the
cells of plants and some animals containing pigments or
starch or oil or protein

Plastid \Plas"tid\, Plastide \Plas"tide\, n. [Gr. ?, ?, a
creator.]
1. (Biol.) A formative particle of albuminous matter; a
monad; a cytode. See the Note under {Morphon}. [Archaic]
--Haeckel.
[1913 Webster]

2. (Bot.) any of several types of minute granules found in
the protoplasm of vegetable cells, having their own
membrane, robosomes, and DNA. Among plant cells the most
common are {chloroplasts}, which contain the chlorophyll
and the photosynthetic machinery of the cell. They are
divided by their colors into three classes,
chloroplastids, chromoplastids, and leucoplastids.
[1913 Webster PJC]
