Prokaryotes

NO Nucleus/ Organelles

Bacteria, Blue-Green Algae (Not Algae, True Bacteria)

Photosynthetic

Eukaryotes

Has Nucleus / Organelles

Protozoa, Algae, Yeast, Mold

Peptidoglycan

Rigid Cell Walls

Mycoplasma

Lack Cell Walls

Mycobacterium

Mycolic Acid in Cell Walls

Flagella

Uses Chemotaxis (move towards/ away from chemical)

Flagella = Motility

NO Flagella = Immotile

Types of Flagella

Monotrichous - 1 Flagella Tail

Lophotrichous - Many in Tail (One side)

Peritrichous - Flagella around

Amphitrichous - Flagella Tails on opposite sides

KNOW for exam /quiz

Protozoa

All Unicellular EUKARYOTES

Usually motile - via Flagella, Cilia, / Pseudopods

NO cell walls

No Chlorophyll

Algae

Rigid Cell Walls of Cellulose

Has Chlorophyll

Carries out plant-like Photosynthesis

Unicellular / Multicellular organisms

EUKARYOTIC except for ** blue-green algae (Cyanobacteria)

Photosynthetic Bacteria

Peptidoglycan Cell Walls

Cyanobacteria/ Purple Sulfur bacteria

Cyanobacteria do Photosynthesis under AEROBIC condition

Photosynthetic bacteria (PURPLE Sulfur bacteria) do Photosynthesis under ANAEROBIC condition

Fungi

EUKARYOTE

NON-photosynthetic (bc NO Chlorophyll)

**Cell Walls of Chitin

Prop by Spores

Live on Dead Organic Materials some parasitic on plants/ animals

Yeasts: Single Cell Fungi, NO mycelium

Molds: HAS mycelium
