Yes. Plastids can interconvert. For example, a leucoplast in a tomato can develop into a chromoplast (red/orange) during ripening.
They are common in non-photosynthetic tissues like roots, tubers (e.g., potatoes), and seeds, where storage is the primary function.
The main subtypes are amyloplasts (starch storage), elaioplasts (lipid storage), and proteinoplasts (protein storage).
