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