Explanation:

(a) The important ribosome function includes:  

• It assembles amino acid to form proteins that are essential to carry out cellular functions.
• The DNA produces mRNA by the process of DNA transcription.
• The proteins synthesized in the cytoplasm are utilized in the cytoplasm itself, the proteins synthesized by bound ribosomes are transported outside the cell.

• Ribosomes are present in both plant and animal cells.

(b) The major functions of centrosome are :  

• The centrosomes help in cell division.

• They maintain the chromosome number during cell division.  

• They regulate the movement of microtubules and cytoskeletal structures, thereby, facilitating changes in the shapes of the membranes of the animal cell.
• Centrosomes are found in animal cells.

(c) The major functions of lysosome are :

• Lysosomes are suicidal bags of the cells. They contain hydrolytic enzymes.
• Their main function is to digest food.
• They also cause lysis of the cells after they die.
• Lysosomes are found in animal cells.
