Standards: CLE 3210.1.1 Compare the structure
and function of cellular organelles in both prokaryotic and eukaryotic cells.
SPI 3210.1.2 Distinguish between prokaryotic and eukaryotic cells
CLE 3210.1.4 Describe the processes of cell growth and reproduction.

Objectives: Differentiate between prokaryotic and
eukaryotic cell division Distinguish DNA structures between
prokaryotic and eukaryotic cells

REVIEW: 2 types of cells
Membrane bound nucleus
Membrane bound organelles
Larger DNA is coiled
around proteins to form chromosomes
NO membrane bound nucleus Nucleiod
NO membrane bound organelles
Smaller DNA is not coiled
around proteins - circular chromosome
Eukaryotes Prokaryotes

Cell Division
Asexual reproduction The cell cycle

Prokaryote Chromosome DNA is NOT coiled around proteins Circular chromosome Attached to the inner surface of the
plasma membrane

Binary Fission•The division of a prokaryotic cell into two identical daughter cells•DNA (circular chromosome) is copied.•Cell grows to twice its normal size•Membrane pinches in toward the middle (like a cleavage furrow)•A new cell wall forms around each membrane•Eventually, the dividing prokaryote is split into two independent, identical cells
