(plas'tid),
1. One of the differentiated structures in cytoplasm of plant cells where photosynthesis or other cellular processes take place; plasid contain DNA and are self-replicating. Synonym(s): trophoplast
2. One of the granules of foreign or differentiated matter, food particles, fat, waste material, chromatophores, trichocysts, etc., in cells.
3. A self-duplicating viruslike particle that multiplies within a host cell, such as κ particles in certain paramecia.

plastid

(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.

plastid

an organelle of plant cells, with a double membrane. Plastids are large (between 3 and 6 μ m in diameter) and have various roles, e.g. a photosynthetic function (CHLOROPLAST) or a storage function (AMYLOPLAST).
