ribosomes are necessary for new proteins to be made.
B)The nucleus acts as a brain for the cell. The ribosomes store proteins for the cell.
C)The nucleus contains genetic material, controlling cell function andinstructions for making new proteins. The ribosomes are where new proteins are made.
D)The nucleus and ribosomes are needed for photosynthesis, providing food for the cell.
