MODULE 7 (THE DIFFERENCE BTWN EUKARYOTIC PROKARYOTIC CELLS)

Cards (16)

  • Prokaryote is an organism made of one cell that does not have a nucleus or other organelles covered by a membrane.
  • Prokaryotes have two types: Bacteria and Archaea
  • The DNA of a prokaryotic cell is a single tangle loop. The DNA is located in the cytoplasm.
  • A prokaryotic cell has a cell wall that surrounds the cell membrane. The cell wall gives structure and support to the cell.
  • The most common prokaryotes are bacteria (singular, bacterium)
  • Bacteria are the smallest known cells. These tiny organisms live almost everywhere. Some bacteria live in the soil and water.
  • Bacteria has no nucleus.
  • Bacteria has circular DNA shaped like a twisted rubber band.
  • Bacteria has no membrane-covered (or membrane-bound) organelles.
  • Bacteria has a cell wall outside the cell membrane.
  • Bacteria has a flagellum (plural, flagella), a tail-like structure that some bacteria use to help them move.
  • Archaea (singular, archaeon) and bacteria share the following characteristics: no nucleus, no membrane-bound organelles, circular DNA, and a cell wall
  • Archaea have some other features that no other cells have.
  • The cell and cell membrane of archaea are made of different substances from those of bacteria.
  • Some archaea live in places where no other organisms could live.
  • Eukaryotic cells are the largest cells. They are about 10 times larger than bacteria cells. However, you still need a microscope to see most eukaryotic cell.
