Prokaryotes and Eukaryotes

• What is a cell?

  A cell is the smallest unit of life that can live on it's own. Makes up all living organisms and tissue.
• What are the differences between eukaryotic cells and prokaryotic cells?

  1.Eukaryotic cells are larger than prokaryotic cells.

  2.Eukaryotic cells have a nucleus

  3.Eukaryotic cells have their DNA enclosed in the nucleus in chromosomes whereas prokaryotic cells have their DNA loose in the cell
• Animal,plant,fungi and protists are what kind of cells?


  Eukaryotic cells.
• What kind of cell is a bacterium?

  Prokaryotic.
• Name 5 sub-cellular organelles that are found in both animal and plant cells?

  1.Mitochondria

  2.Cytoplasm

  3.Ribosomes

  4.Cell membrane

  5.Nucleus
• Cell membrane

  controls which substances can pass in and out of the cell
• How does the DNA in prokaryotic cells look like?


  It is a single loop of DNA and can have plasmids.
• Plasmids


  small rings of DNA

  3.vacuole
• Nucleus


  Stores DNA and controls the cell's activity
• Cytoplasm


  jelly-like substance where chemical reactions take place
• Structure of cytoplasm


  contains enzymes, nutrients,dissolved ions and organelles
• Mitochondria
