Presentation transcript:

Mitosis Why divide? -Reproduction -Growth -Repair

Two Types of Reproduction Asexual Sexual What are the advantages and disadvantages of sexual vs. asexual reproduction?

Process of Cell Division Genetic material? Chromosomes Prokaryotes Eukaryotes

Cell Division Why condense the chromatin into chromosomes? Eukaryotic vs. Prokaryotic Prokaryotic: Binary fission

Cell Cycle Interphase Mitotic phase G1 S G2 Very tightly controlled. Why?

DNA Vocab Several versions Chromatin- DNA and proteins during interphase Chromosomes Tightly coiled DNA that condense prior to division Chromatid

Haploid vs. Diploid Haploid Diploid 1 copy of every chromosome (n) Diploid 2 copies of every chromosome (2n) How many chromosomes do humans have? Pairs?

Mitosis Non-reductive Identical daughter cells PMAT

Cytokinesis Cell plate formation in plants Cleavage furrow or contractile ring occurs in animal cells
