∙ Plastids are organelles found in plants and algae. They are responsible for manufacturing and storing food.
∙ Chloroplasts, chromoplasts, and leucoplasts are the three types of plastids.
∙ Chloroplasts contains the green coloured pigment called chlorophyll, which help in absorbing sunlight for photosynthesis.
∙ Chromoplasts are plastids found in coloured parts of plants such as petals, pericarp of the fruits, etc., other than green.
∙ Leucoplasts are the colourless plastids, involved in the storage of carbohydrates, fats, and oils and proteins.
