10. Cells  There are MANY types of cells.

11. Cells  Cells can be divided into two groups based on the presence of organelles.  Organelles – membrane bound structures with specific functions in some cells.

12. Cells  Prokaryotes – (pro means first) cells that do not contain organelles.  DNA not contained in nucleus.  Seen in unicellular (one cell) like bacteria.

13. Cells  Eukaryotes - Cells that contain membrane bound organelles.  Seen in multicellular organisms and unicellular organisms like protists, algae and yeast.  Allows chemical reactions to happen in different parts of the cell at the same time.
