plant, animal, bacteria and yeast cells

Animal cells contain:

• cell membrane
  • controls the passage of substances in and out of the cell
• nucleus
  • controls all the cell activity
  • contains the genetic material
• cytoplasm
  • a liquid gel in with most of the chemical reactions for life take place
• ribosomes
  • where proteins are synthesised
• mitochondria
  • release energy during respiration

Plant cells contain all the sub-cellular structures found in animal cells

They also have:

• cell wall made of cellulose
  • strengthens the cell
• a large, permanent vacuole
  • contains cell sap
  • gives support to the plant
• chloroplasts
  • contain chlorophyll
    • absorb light to make food (glucose) by photosynthesis

chromosome and plasmids contain genes

no nucleus

a cell wall of sugar/protein

genes on chromosome inside the nucleus

cell wall made of chitin
