Cells

• What does the nucleus contain?

  Genetic material
• What are eukaryotic cells?

  Cells which contain their genetic material (DNA) enclosed in the nucleus
• What are prokaryotic cells?

  Genetic material is not enclosed in the nucleus
• Prokaryotic cells are much smaller than eukaryotic cells
• Mitochondria

  Where most of reactions for aerobic respiration take place
• Cytoplasm

  Gel like substance where most of the chemical reactions happen
• Cell membrane 


  Holds the cell together and controls what goes in and out
• Ribosomes

  These are where proteins are made in the cell
• What are examples of eukaryotes?

  Animal and Plant
• What are examples of prokaryotes?

  Bacteria
• What are cells?

  The basic building blocks of life
• What are small rings of DNA called?

  Plasmids
• What is the vacuole?

  A large sac in the middle of the cell that contains a watery solution of sugars and salt (cell sap)

  It helps to maintain the strucutreand shape of a cell
• What is the cellwall made out of?

  Cellulose, this makes it strong and allows it to maintain the shape of the cell
• Prokaryotes have a single DNA loop
• What do animal cells contain?

  • Cell membrane
  • Nucleus
  • Cytoplasm
  • Mitochondria
  • Ribosomes
• What do plant cells contain?

  • Cell membrane
  • Nucleus
  • Cytoplasm
  • Mitochondria
  • Ribosomes
  • Cell wall
  • Vacuole
  • Chloroplasts
• What 3 things does a plant cell contain that an animal cell doesn't?

  • Cell wall
  • Vacuole
  • Chloroplasts
• What do bacteria cells contain?

  • Cell wall
  • Cytoplasm
  • Cell membrane
  • Ribosomes
• What do bacteria cells not contain?

  • Mitochondria
  • Chloroplasts
  • No nucleus - only a single loop of DNA
• Chloroplasts

  These are where photosynthesis occurs, they contain chlorophyll
• What does chlorophyll do?

  Absorbs the light needed for photosynthesis
