Cell wall
A tough outer covering that lies just outside the cell membrane in plant cells.

Mitochondria
Organelles in plant and animal cells that use oxygen to get energy from processing food.
Ribosomes
Manufacture proteins inside the cell.
Vacuoles

Golgi apparatus
Takes the materials manufactured by the endoplasmic reticulum and finishes processing them.
Lysosome
Found in animal cells that break down materials taken into the cell.
