Plastid
A cell-body (organellae) in plants other than nucleus, mitochondria and centrosome. Proplastides develop to leukoplasts (or etioplasts in the absence of light) which develop to chloroplasts and/or chromoplasts.

Plastids
Chloroplasts are the most familiar plastids. They are usually disk-shaped and about 5-8 µm in diameter and 2-4 µm thick. A typical plant cell has 20-40 of them.

plastids Membrane-bound organelles in plant cells that function in storage (of food or pigments) or food production. Term for any double membrane-bound organelle.

Mitochondria and plastids
Mitochondria are organelles found in nearly all eukaryotes. They are surrounded by double membranes, the inner of which is folded into invaginations called cristae, where aerobic respiration takes place.

Mitochondrial and plastid genomes contain much less genetic material than their hypothesized endosymbiont ancestors, yet still contain almost as many organelle-specific proteins as are present in those ancestors.

This single-celled organism is photoautotrophic and capable of oxygenic photosynthesis. Synechocystis contains more than 126 genes related to photosynthesis, and about 90% of algal plastid genes appear to be conserved in Synechocystis.
