plas·tid

 (plăs′tĭd)
n.
Any of several cytoplasmic organelles, such as chloroplasts, that contain genetic material, have a double membrane, and are often pigmented. Plastids are found in plants, algae, and certain other eukaryotic organisms and have various physiological functions, such as the synthesis and storage of food.

[From Greek plastis, plastid-, feminine of plastēs, molder, from plastos, molded; see plastic.]

plas•tid

(ˈplæs tɪd)

n.
a small, double-membraned organelle of plant cells and certain protists, occurring in several varieties, as the chloroplast, and containing ribosomes, prokaryotic DNA, and, often, pigment.
