Answers
l).
Function of Plastids:-
• Chloroplasts are important for photosynthesis in plants.
• Chloroplasts also contain various yellow or. orange pigments in addition to chlorophyll.
• Leucoplasts are primarily organelles in which materials such as starch, oils, and protein granules are stored.
ll).

1. Chromoplasts (Colored Plastids: Chloroplasts - Green pigmented and useful in Photosynthesis and also contains various other pigments like (yellow and orange)
2. Leucoplasts (White or colorless plastids; stores materials such as oils, proteins, fats etc. )
Plastids are also covered by a double membrane.
The matrix is called Stroma, seat for enzymatic actions.
Plastids have their own DNA and Ribosomes; therefore they can make their own proteins.
