Four different types

Different cell types in different organisms 

     Bacteria                  Fungi                      Animal                    Plant

Characteristics of different celltypes

- Cell wall (made of cellulose)

- Cell membrane

- Cytoplasm

- Nucleus

- Chloroplasts

- Mitochondria

- Vacuole

Bacteria    Fungi     Animal      Plant

Different types of cells within one organism 

Despite looking different all still show the characteristics of animal cells

Shape and size depend on function!
