Cells

• Describe evidence to show it is a prokaryotic cell


  • Plasmids are present in the figure (1) which are only found in prokaryotes and not in eukaryotes (1).

  • Prokaryotes have a capsule layer (1) whereas eukaryotes do not (1).
• The RER IS involved inpassive transport, for example, diffusion. Give two pieces of evidence to support this statement.

  • it has microvilli which further increases surface area (1)

  • the cell is in the small intestine which is involved with absorption (1)

  • the cell has a good blood supply / lots of capillaries / close to a capillary (meaning a short diffusion distance) (1).
