Cytology

• Cytology study of the structure and function of
  cells.
• Cytoplasm area of space outside the nucleus but
  which is contained within the cell membrane
  contains the organelles and cytosol. The
  organelles are tiny structures in the cytoplasm
  which perform various jobs for the cell. The
  fluid part of the cytoplasm is called the cytosol.

4

• Nucleoplasm is the area of space found inside
  the nucleus.

5
Prokaryotic Cells

• They lack a nuclear membrane as well any other
  membrane covered organelles in their cytoplasm.
• Considered to be Primitive Cells
• Example Bacteria Blue-Green Algae

6
Eukaryotic Cells

• They possess a nuclear membrane as well as
  membrane bound organelles in their cytoplasm.
• Example Plant Animal Cells

Questions

• Read the section on Prokaryotes and Eukaryotes on
• pages 172 to 173 and answer the following
  questions.
• What 2 characteristics do all cells have in
  common?
• What does DNA stand for? Where is the genetic
  material DNA found in a prokaryotic cell?
• Which are generally larger, eukaryotic or
