4. Mitochondria: It is rod-like in shape. It is found in the cytoplasm which produce energy for the cell. It is often called the powerhouse of the cell.






5. Endoplasmic Reticulum: a system of tube and channel which connect to the nucleus and cell membranes. It transports materials between cytoplasm and cell membrane and the nucleus.





6. Vacuole: it is an enclosure within the cytoplasm in plant cells. It is large and contain cell sap.






7 Lysosomes: it is a tiny spherical body containing digestive enzymes. They digest and destroy foreign bodies. Ribosomes - A tiny granule formed freely in the cytoplasm where they synthesize the proteins.





8. Cell Wall: This encloses the cell membrane. It is found in a plant cell into usually made up celluslose to support the plant.
