1. Today’s Objectives
TSW distinguish between plant and animal cells and diagram them.
TSW distinguish between prokaryotes and eukaryotes.

2. Plants, Fungi & Animal Cells
Plants Only
Cell wall of cellulose
Central vacuole
Chloroplasts
Animals Only
Lysosomes
Centrioles
Fungi Only
Cell wall of chitin
Central vacuole
No chloroplasts

3. Prokaryotes – “Bacteria”
Simplest and oldest form of life
Usually single celled

4. Prokaryotes are ABUNDANT
They can live in any environment on Earth
Eubacteria – common bacteria
Archaebacteria – ancient bacteria; live in harsh environments

5. Eukaryotes vs. Prokaryotes
Nucleus & Organelles
Linear chromosomes
Unicellular or multicellular
Cell wall (plants & fungus)
Cell membrane (all)
Prokaryotes
No organelles
Circular chromosomes
Unicellular or colonial
Cell wall
Cell membrane
