Cell Organelle — Types & Functions

What Organelles Are in a Cell?

Some of the most commonly found organelles in eukaryotic cells are:

The nucleus, which is what holds the DNA;

The nucleolus, which makes ribosomes;

The smooth endoplasmic reticulum, which packages proteins in vesicles;

The rough endoplasmic reticulum, which is covered in ribosomes that create proteins;

The centrioles, which guide the separation of the cell during mitosis;

The chloroplast, which photosynthesizes in plant cells;

The lysosome, which can destroy bacterial invaders;

The vacuole, which can store many materials;

The mitochondria, which perform cellular respiration;

The Golgi complex, which sends and receives protein packages.

Remember: Prokaryotic cells do not have membrane-bound organelles, so you will not find these structures inside them.
