Solution
The correct option is B (i)-(C), (ii)-(B), (iii)-(A), (iv)-(D) Plastids are double membraned organelles that can store or synthesize various organic compounds. Plastids can be found in plants, and some protists. Based on their colour and pigment contained, they are classified as follows.
Leucoplasts: Colourless plastids. There are three important types of leucoplasts: * Amyloplast: Leucoplasts that store starch and other simple sugars. * Elaioplast: Leucoplasts that store fats and oils. * Aleuroplasts: Leucoplasts that store proteins.
Chromoplasts: These can be orange, red, or yellow in colour due to the presence of carotenoid pigments.
Chloroplasts: These are the green coloured plastids that contain chlorophyll and take part in the synthesis of food through photosynthesis.
