3. Organelles such as mitochondria and vacuoles are also present in the cytoplasm.

4. A plant cell has a cell wall and organelles called chloroplast which contain chlorophyll.

Animal cell do not have a cell wall or chloroplast also the vacuoles in a plant cell and large .

5. New cells for growth and repair are formed by cell division.
