all unpigmented plastids. Their function differs from the leucoplasts of plants.
* Apicoplast: the non-photosynthetic plastids of Apicomplexa derived from secondary endosymbiosis.

The plastid of photosynthetic Paulinella species is often referred to as the 'cyanelle' or chromatophore, and is used in photosynthesis. It had a much more recent endosymbiotic event, in the range of 140-90 million years ago, which is the only other
