Bacterial cells

Bacterial cell

Bacteria are single-celled organisms.

Key points to note when comparing and contrasting the structure of bacterial cells with animal and plant cells are that they:

  • Do not contain a nucleus - DNA is a circular chromosome that floats in the cytoplasm.
  • Have a cell membrane.
  • Have cytoplasm
  • Have a non-cellulose cell wall
  • Have plasmids - rings of DNA floating in cytoplasm also.
