Prokaryotes, Eukaryotes, and Cell Division

Eukaryotes

Eukaryotes• Eukaryotes are organisms whose cells

contain a “true” nucleus

• These cells are usually large and complex

• Examples: Plants, Animals, Fungi, Protists

Plant vs. Animal Cells

Plant vs. Animal Cells• Plant cells have:

– A Cell Wall (used for structure)

– A Central Vacuole (used to maintain turgor pressure)

– And Chloroplasts (needed for photosynthesis)

Prokaryotes

Prokaryotes• Prokaryotes are organisms whose cells lack a

“true” nucleus

• These cells are usually small and simple, lacking most organelles common to a eukaryote

“true” nucleus

• Example: Bacteria

“true” nucleus

daughter cells
