    • What is organelle b and it’s function?

      Chloroplast - for photosynthesis, uses light energy to produce starch
    • What are 2 structures present in plant cells but not in animal cells?
      Chloroplasts and cell walls
    • Name structures W to Z in the diagram
      W - cell membrane
      X- cell wall
      Y- capsule
      Z- flagellum
    • Name the biological molecule in
      W- cell membrane = phospholipids
      X- cell wall = murein
    • what is the process by prokaryotic cells divide
      Binary fission
    • give 2 ways in which the arrangement of prokaryotic dna is different from arrangement of human dna.

      prokaryotic dna is circular as opposed to linear
      Prokaryotic dna is also not associated with proteins
    • Write evidence that
      • cell b is an animal cell
      • Cell c is a prokaryotic cell
      B - no cell wall
      C- has a capsule
    • Cell A is a plant cell. name a polysaccharide which may be found in cell a but not in an animal cell
      Cellulose
    • Penicillin is an antibiotic. It prevents the formation of bacterial cell walls. as a result bacterial cells that have been treated with penicillin swell and burst.
      Suggest why penicillin has no effect on plant cells.
      Plant cell wall is made of a different substance
    • two structures found in a prokaryotic cell that are not found in human cells.
      Cell wall, capsule
    • What is in a bacterium out of these? Cell surface membrane, nucleus, cytoplasm, capsid
      Cell surface Membrane, cytoplasm
    • What is in a virus out of these? Cell surface membrane , nucleus , cytoplasm capsid.
      Only capsid
    • Which of the following is present in a bacterium ? RNA, cell wall , enzyme molecules and capsid
      Bacterium have rna, cell wall and enzyme molecules
    • Which of the following is present in hiv? rna, cell wall, capsid, enzyme molecules.
      HIV has rna, enzyme molecules and a capsid
