MCQs On plastids For NEET 

Plastids are double membrane organelles which take part in storing or synthesizing organic compounds. These occur in plants and some protists. Plastids develop from colourless precursors called proplastids. The proplastids can divide and differentiate into 3 main types of plastids leucoplast, chromoplast and chloroplast.
