Today’s Objectives • TSW distinguish between plant and animal cells and diagram them. • TSW distinguish between prokaryotes and eukaryotes.
Plants Only Cell wall of cellulose Central vacuole Chloroplasts Animals Only Lysosomes Centrioles Plants, Fungi & Animal Cells • Fungi Only • Cell wall of chitin • Central vacuole • No chloroplasts
Prokaryotes – “Bacteria” • Simplest and oldest form of life • Usually single celled
Prokaryotes are ABUNDANT • They can live in any environment on Earth • Eubacteria – common bacteria • Archaebacteria – ancient bacteria; live in harsh environments
Eukaryotes 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 Eukaryotes vs. Prokaryotes
