  3. On the basis of function plastids are of three types - Leucoplast, Chloroplast and Chromoplast. All types of plastids have common origin from proplastids, sac like non-lamellar structures. Different types of plastids may transform from one form to another. But chromoplasts never transform to chloroplasts.
