Answer 1

• In plants plastids are responsible for the colouring of fruits and vegetables.
• There are 3 types of plastids present in plants. 
• Chloroplasts are responsible for green colour. 
• Chromoplasts are responsible for different colours, i.e., orange, yellow, red etc. 
• Leucoplasts are responsible for white colour. 
• These plastids have the capacity to change from one form to another.
