Centrioles

Centrioles are a pair of structures composed of microtubules and their main function is to generate the cell's cytoskeleton. Centrioles are only in animal cells.

The two light grey parallel lines are the centrioles.

Lysosome

Lysosomes are large vesicles formed by the Golgi that  function in the extracellular breakdown of materials. The enzymes within lysosomes could potentially destroy the cell so there is a membrane surrounding it preventing it from doing so. Lysosomes are found only in animal cells.

Chloroplasts

Chloroplasts are another organelle that is only found in plant cells. Chloroplasts contain chlorophyll molecules which absorb the sun's energy and convert it to chemical energy which can be used to fuel chemical reactions in the cell. 

Cell Wall

The cell wall is the backbone for plant cells. This is not found in animal cells because they have other ways of support as in skeletons and exoskeletons. The cell wall supports and hold together everything in the cell and protects it from foreign objects.

The area in green around the plant cell above is the cell wall.

Nucleolus

Located within the nucleus, the purpose of the nucleolus is ribosome production. It is composed of protein and nucleic acids.

The maroon figure is the nucleolus.

Mitochondrion

The mitochondria are best known as being the powerhouse for a cell. Their function is the site of energy release and ATP production. Mitochondria have a double membrane.
