What are other cell parts?

2. Organelles
Organelles: is a small structure inside a cell that has its own special function.

3. Mitochondria
Mitochondria: structure that makes energy for a cell. They are known as a “powerhouses” of the cell.

4. Endoplasmic reticulum
Endoplasmic reticulum: a small network of tubes inside a cell that substances move along.

5. Ribosomes
Ribosomes: a small, round structure that makes proteins. Proteins are needed for growth and life processes. Ribosomes are either attached to ER or scattered in the cytoplasm.

6. Golgi Bodies
Golgi bodies: is an organelle that packages and sends materials to other places in the cell.

7. Vacuoles
Vacuoles: a space in the cytoplasm that stores food and waste (usually water). Plant cells have usually one big vacuole, whereas animal cells have many small vacuoles.

8. Lysosomes
Lysosome: a small round structure that have chemicals breaking down nutrient molecules and old cell parts. When some organelles stop working, lysosomes break down and recycle old cell parts so that they can be used again.

11. Checking concepts: What are organelles?

12. Why are the mitochondria called the “powerhouses” of the cell?

13. What are the small storage spaces in a cell called?

14. What is the job of the Golgi bodies?

15. How are the lysosomes like a cleanup crew?
