Cells

• The nucleus is the control center of the cell, containing the genetic material (DNA).
• Eukaryotic: An organism that contains a nucleus
• Prokaryotic: An organism that conatains no nucleus
• Cell membrane: Controlls what goes in or out of the cell


  Cytoplasm: Where chemical reactions takes place

  Mitcochondria: Where aerobic repsiration takes place

  Ribosomes: Where protein synthesis takes place (makes proteins)

  Cell wall: Keeps strcture of cell

  Vacuole: Storage space that contains sap

  Chrloroplast: Contains chrlorphyll that absorbs sunlight for photosynthesis
• Yeast is unicellular
• Features of animals:

  • Heterotrophs
  • Multicellular
  • Reproduce sexually
• Features of plants:

  • Autotrophs
  • Multicellular
• Saprotrophic nutrition:

  1. Fungi feed by a special type of heterotrophic nutrition called 'saprotrophic' nutrition. 
  2. First, they secrete digestive enzymes out of their body, onto the food.
  3. These break down and digest the food.
  4. They then absorb the small nutrients into their cells. 
• Parasite:

  An organism that depends on another organism to grow and reproduce.
• Bacteria divide by binary fission
• Bacteria are unicelluar which means they divide by binary fission, they're also reproducing as each new cell is a seperate oraganism.
