Title: Prokaryotic and Eukaryotic cells


1
Prokaryotic and Eukaryotic cells
2
What is a Prokaryotic Cell?
  • Prokaryotic cells are cells that do not have a
    true nucleus the DNA in prokaryotic cells is not
    completely separated from the rest of the cell by
    a nuclear membrane (envelope) and is not arranged
    in strands called chromosomes.
  • Prokaryotic cells do not have membrane bound
    organelles.
  • Prokaryotic cells are bacteria

3
What is a Eukaryotic Cell?
  • Eukaryotic cells have the DNA is organized into
    structures called chromosomes and the chromosomes
    are separated from the cytoplasm by a nuclear
    membrane.
  • Eukaryotic cells have membrane bound organelles.
  • Eukaryotic cells are animal, plant, fungi, and
    protist.

4
Prokaryotic cells differ from eukaryotic cells in
other ways
  • Prokaryotic cells lack most of the other
    organelles which are present in the cytoplasm of
    eukaryotic cells.
  • Prokaryotic cells do not contain mitochondria but
    they can obtain energy from either sunlight or
    from chemicals in their environment.
  • Prokaryotic cells, however, do contain ribosomes,
    the site of protein synthesis.
  • Most prokaryotes are unicellular organisms, such
    as bacteria.
