Cell Division Chromosomes Function/Role Not dividing - Interphase Cell divides Comparison of Mitosis & Meiosis
Chromosomes Haploid (n): one set of chromosome in nuclei Diploid (n): two sets of chromosomes are present in nuclei
Function/Role Mitosis
Mitosis Asexual reproduction Gamete formation in flowering plants Cell replacement
Function/Role Mitosis Meiosis
Meiosis Genetic variation Sexual reproduction Spore formation: e.g. flowering plants Gamete formation in animals, e.g. egg and sperm
Function/Role Mitosis Meiosis
Not dividing - Interphase Proteins are made Cell grows Organelles are made DNA replication
Cell divides Mitosis
Mitosis Prophase Metaphase Anaphase Telophase Cancer
Cancer Biological agents - viruses Physical - X-rays, UV light Environmental - cigarette smoke, benzene
Mitosis Prophase Metaphase Anaphase Telophase Cancer
Cell divides Mitosis Meiosis
Meiosis Location in humans
Location in humans Testes - sperm, haploid male gametes, Ovary - egg, haploid female gametes
Meiosis Location in humans Location in flowering plants
Location in flowering plants Anther of the stamen - haploid male spores Ovule of ovary - haploid female spores
Meiosis Location in humans Location in flowering plants

Comparison of Mitosis & Meiosis Meiosis
Meiosis Not identical daughter cells
Not identical daughter cells diploid organisms only 2n

Comparison of Mitosis & Meiosis Meiosis Mitosis
Mitosis Identical daughter cels
Identical daughter cels Both diploid and haploid organisms n - 2 x n 2n - 2 x 2n
