Explanation:

1. Mitochondria are the power - houses of the cell, making usable energy (ATP) through cellular respiration.
2. Ribosomes are the sites of protein synthesis in the cell.
3. The rough endoplasmic reticulum is covered in ribosomes and transports proteins.
4. The cytoskeleton helps maintain the cell's internal structure and shape.
5. The cell membrane is a semi - permeable barrier separating the cell from the external environment.
6. The nucleus holds the cell's genetic information in the form of DNA.
7. The Golgi apparatus receives vesicles, modifies their contents, and ships them to their destinations.
8. Lysosomes are full of enzymes for digesting and destroying foreign objects.
9. The smooth endoplasmic reticulum breaks down poisons and makes lipids.
10. To leave the cell, one would pass through the cytoplasm and the cell membrane.
