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 ABUNDANTThey can live in any

environment on EarthEubacteria – common bacteriaArchaebacteria – 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
