GENERAL KNOWLEDGE

Detailed explanation-1: -Plastids are a pigment containing double membrane-bound organelle which is the site of manufacture and storage of chemical compounds. Plastids are of three types on the basis of the pigments present within them:-1. chloroplast (green plastid), 2. The chromoplast (coloured plastid) and 3.

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: -Leucoplasts are plastids that are colourless or non-pigmented. Instead of chloroplasts, which contain chlorophyll (the green pigment), and chromoplasts, which contain other photosynthetic pigments, leucoplasts are devoid of photosynthetic pigments.

Detailed explanation-4: -The photosynthesis process is mainly based on chlorophyll pigment. Also, there are other red and yellow pigments that help in this biological process. This includes carotenoids (yellow-orange), xanthophylls (yellow), and betalain (red) pigments.
