Prokaryotic + Eukaryotic cells

• Prokaryotic cells

  • small and simple
  • eg. bacteria

  Sub cellular structures

  • Cell membrane - controls what goes in and out
  • Plasmids - small loops of DNA
  • Chromosomal DNA - controls cells activities

  
• Eukaryotic cells

  • complex cells
  • eg. animals and plants

  
• Animal cells

  • Nucleus - contains DNA that controls activities
  • Cytoplasm - chemical reactions occur here
  • Mitochondria - site of respiration
  • Ribosomes - where proteins are made
  • Cell membrane - controls what goes in and out

  
• Plant cells

  • Nucleus - contains DNA which controls activities
  • Cytoplasm - chemical reactions occur here
  • Mitochondria - site of respiration
  • Ribosomes - where proteins are made
  • Cell membrane - controls what goes in and out of the cell
  • Cell wall - gives support to the cell (made of cellulose)
  • Chloroplasts - where photosynthesis occurs
