Prokaryotic cells

Cell wall (bacterial cells)

• for protection

• made with peptidoglycan

Genetic material

• Single strand of DNA

• no nucleus

• floats freely in the cytoplasm

Ribosomes

smaller than those of eukaryotes

Plasmid

• extra circular sloops of DNA which carry beneficial genes

Flagellum

For extra movement

Capsule

Protective outer layer

Which do not have a mitochondria

a. fungi

b.animal

c.bacteria

d.plant

c.bacteria

Compare between Bacteria and Animal cells (8 points)

Differences:

Animal cells have a nucleus, bacteria cells do not

The DNA for animal cells is stored in the nucleus, while it is a single strand floating freely in bacteria

Some bacteria have a capsule, no animal cells have, most outer layer being cell membrane

Some bacteria have a flagellum, no animal cells have a flagellum

Bacteria have a flexible cell wall, animal cells have no cell wall

Bacteria cells are prokaryotic, Animal cells are eukaryotic

Bacteria have smaller ribosomes, animal cells have longer ribosomes

Bacteria cells have few organelles, animal cells have many

Similarities:

Both have ribosomes

Cell membrane

Cytoplasm

DNA
