MITOSIS VS.

BINARY FISSIONHonors BiologyMrs. Stewart

Central Magnet School

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

Interphase Mitosis

Binary FissionEukaryotes Prokaryotes

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
