Prokaryotic and Eukaryotic Cells

Procaryotic:
      - simple (Prehistoric, Procaryotic)
      - no nucleus or cell parts are evident (has ribosomes)
      - cytoplasm is “soup like”
      - evolved early on
      - have cell walls and membranes
      - carry on regular life functions
      - bacteria, blue-green algae
      - DNA are usually in a ring formation

Eukaryotic:
      - has a distinct nucleus
      - has membrane bound organelles (mitochondria, lysosomes etc.)
      - evolved later on than prokaryotes
      - animal and plant cells

Study Questions

   1.      Connect the functions of the following cell organelles:
              i) Nucleus, Golgi apparatus, Vesicle, Rough E.R.
              ii) Food vesicle, Golgi apparatus, Lysosome
              iii) Chloroplast, Mitochondria
              iv) Ribosome, Polysome, Nuclear pore, Nucleolus

   2.      How does the Golgi apparatus work?

   3.      What are the differences between animal and plant cells? (make a table)

   4.      What are the roles of microtubules and filaments in the cell cytoskeleton, in
           centrioles, and in flagella?

   5.      Explain the role of the E.R. including the terms rough, smooth and
           ribosomes.
