What are Living Organisms Made Up of?
These cells contain many structures called organelles that perform various roles which help the cell to sustain itself. The common cell organelles are:

1. Nucleus
2. Cell wall
3. Cytoplasm
4. Endoplasmic reticulum
5. Golgi apparatus
6. Lysosomes
7. Mitochondria
8. Plastids
9. Vacuoles

However, certain cell organelles are specific to certain cells. For instance, cell walls and vacuoles are exclusive to plant cells. Lysosomes are seen only in animal cells, but they perform similar functions as vacuoles in plant cells.
