What are the different types of plastids?

Answer 1

Chromoplasts - are red, yellow or orange in color and are found in petals of flowers and in fruit. Their color is due to two pigments, carotene and xanthophyll.

Leucoplasts - are colorless plastids and occur in plant cells not exposed to light, such as roots and seeds. They are colorless due the absent of pigments.

Chloroplasts - are probably the most important among the plastids since they are directly involved in photosynthesis. They are usually situated near the surface of the cell and occur in those parts that receive sufficient light, e.g. the palisade cells of leaves. The green color of chloroplasts is caused by the green pigment chlorophyll.

Answer 2

These are Leucoplasts: storage plastids (named after what they store)

Amyloplast which stores starch

Elaioplast which stores oils and lipids

Proteinoplast...self explanatory.

These have other functions that may or may not include pigments to effect their colors.

Chromoplast which is rich in chlorophyll and undergoes photosynthesis

Etioplasts which are chloroplast that have not been exposed to light. Very commonly found in angiosperms grown in the dark

Proplastid which is a very young plastid found in meristomatic cells (growth cells)
