1. The Cell Types The Basic Unit of Life Is the CELL. * Life doesn’t exist outside a cell. The Basic Unit of Life Is the CELL. * Life doesn’t exist outside a cell.

3. Cytology- The Study Of Cells  Unicellular life (one cell)  Multicellular life (many cells) Carry on similar ‘life activities’ ie: reproduction, obtaining NRG, removing waste, etc.

4. Prokaryotic Cells Eukaryotic Cells No Central Nucleus Less complex yet still carry out every activity associated with living things. EXAMPLE: Bacteria Central Nucleus which contains their genetic material. EXAMPLES: Animal & Plant Cells 2 Types of Cells: All cells have two structures in common: cell membrane and DNA.

5. Eukaryotic Animal Cell Animal Cells Have: lysosomes, centrioles, flagella Not in Animal Cells: a Cell Wall, large vacuole, & chloroplast Eukaryotic Plant Cell Plant Cells Have: a Cell Wall, large vacuole, & chloroplast Not in Plant Cells: lysosomes, centrioles, flagella

6. Virus  Contains DNA or RNA surrounded by a protein coat  Can replicate only by infecting living cells. It needs a host.
