Detailed explanation-1: -Plastids are the coloured bodies that are found only in the plant cells. They contain various pigments which impart color to the plant.

Detailed explanation-2: -Plastids are double-membrane organelles which are found in the cells of plants and algae. Plastids are responsible for manufacturing and storing of food. These often contain pigments that are used in photosynthesis and different types of pigments that can change the colour of the cell.

Detailed explanation-3: -Chromoplasts are coloured plastids that produce and store pigment. Carotenoid pigments found in chromoplasts enable the various colours we see in leaves and fruits. Its distinctive colour is primarily aimed at attracting pollinators. Chromoplasts contribute bright red, orange, and yellow colours to many fruits.

Detailed explanation-4: -Undifferentiated plastids are called “proplastids” and are mainly found in meristematic and reproductive tissues, and they are identified as being small and having clear ultrastructures. They can be differentiated into “leucoplasts” in white, “chloroplasts” in green, and “chromoplasts” in either yellow, orange or red.

Detailed explanation-5: -They contain the green pigment called chlorophyll. Green coloured plastids are called chloroplasts.
