A-level Biology Notes

what is bacteria made of?

-No nucleus -loose DNA in the form of a single loop and plasmid.

-no membrane bound organelles: smaller ribosomes, mesosomes - infolding of cell membrane for respiration

-cytoplasm

-cell membrane and cell wall (made of peptidoglycan/ murein)

-some have a capsule (reduce water loss, protect from phagocytosis) and flagella (movement)
