Comparing Prokaryotic Cells with Eukaryotic Cells
Cells in our world come in two basic types, prokaryotic and eukaryotic. "Karyose" comes from a Greek word which means "kernel," as in a kernel of grain. In biology, we use this word root to refer to the nucleus of a cell. "Pro" means "before," and "eu" means "true," or "good." So "Prokaryotic" means "before a nucleus," and "eukaryotic" means "possessing a true nucleus."

Prokaryotic Cell Believed to be the first cells to evolve.
No “true” nucleus Lack a membrane bound nucleus No membrane bound organelles. Ribosomes are only organelle.
3
Prokaryotic Organisms
Prokaryotes are unicellular organisms The largest group of organisms, mostly due to the vast assortment of bacteria which comprise the bulk of the prokaryote classification. Kingdom Monera has been SPLIT- Archaebacteria, Eubacteria Archaebacteria-hot springs, deep ocean vents Halobacterium, Thermophiles Eubacteria- everywhere Examples: Staphylococcus, Escherichia coli (E. coli), Streptococcus
4
Types of Bacteria Bacillus Coccus Staphylococcus aureus
Escherichia coli (E. coli )
5
Organelles of Prokaryotic Organisms
Cell Wall Cytoplasm Cell Membrane Ribosomes
6
Eukaryotic Organism “True nucleus”; contained in a membrane bound structure. Membrane bound organelles. Thought to have evolved from prokaryotic cells.
7
Eukaryotic Cell Eukaryotes are generally more advanced than prokaryotes. ALL multicellular organisms contain eukaryotic cells Kingdoms:Protista, Fungi, Plantae and Animalia Protista-UNICELLULAR Examples: Paramecium, Euglena, Amoeba (Yeast-Fungi) Fungi, Plantae, Animalia- MULTICELLULAR Examples: Mushroom, Moss, Salmon
8
Eukaryotic Organelles
Nucleus Cytoplasm Mitochondrion Cell Membrane Endoplasmic Reticulum Ribosomes Vacuole Lysosome Plants/Fungi Chloroplast Cell Wall
9
Eukaryotic Cells come in ALL shapes & sizes!
Red Blood Cells Heart Muscle Cells Brain Cell Human Bone Cells
