Solution

The correct option is B
they help in giving shape to the cell

Plastids are only found in plants. They are double-membrane organelles. The chloroplast is a plastid which gives leaves their characteristic green colour. This happens because they contain green-coloured pigments called chlorophylls. The shape of a plant cell is primarily defined by the cell wall and not by plastids.
