Answer:
There are four main types of plastids:
Chloroplasts.
Chromoplasts.
Gerontoplasts.
and Leucoplasts.
Chloroplasts:- are the green plastids which contain chlorophyll pigments for photosynthesis.
Chromoplasts:- are the coloured plastids for pigment synthesis and storage. ...
Gerontoplasts:- are the chloroplasts that are going through the ageing process.
Leucoplasts are colorless plastids
found in endosperm, tubers, roots and other non-photosynthetic tissues of plants. They serve various functions, for example, storage of starch, lipids, or proteins. Plastids of these three types are respectively known as amyloplasts, elaioplasts, and proteinoplasts.
