The

1
The M phase of the cell cycle. Is it Mitosis or
Meiosis?

• Cell Division
• 2 kinds for 2 different types of cells in living
  things.

2
What kind of cells?

• Mitosis
• Found in asexual Somatic cells (body cells)
• plant and animal tissue such as non-flowering
  plants and body tissues like toes, nose, ear,
  stomach etc

• Meiosis (SEX)
• Found in sexual cells called Gametes (sperm and
  egg)
• Plant and animal tissues such as flowers, pine
  cones, and body parts related to sexual
  reproduction.

Terms related to Mitosis and Meiosis

• Mitosis
• Asexual
• Somatic
• Identical daughter cells
• Binary Fission (bacteria)
• Conjugation (Protists like amoebas and
  parameciums)

• Meiosis
• Sexual
• Gametes (sperm, eggs)
• Polar bodies nonfunctioning eggs
• Diploid (2N) where N represents the chromosome
  number
• Haploid (N) sex chromosomes ½ the chromosomes
  number given from Mom or Dad
• Homologous chromosomes same size and same shape
  or structure
• Crossing over of genes in the chromosomes

Crossing over of Homologous Chromosomes

Compare Mitosis and Meiosis

• Both cell divisions go through the cell cycle
• Both cell divisions undergo Prophase, Metaphase,
  Anaphase, Telophase and Interphase
• Both Mitosis and Meiosis are considered the M
  phase of the cell cycle

6
Contrast Mitosis and Meiosis

• Mitosis
• Found only in somatic cells
• Goes though cell division 1 time
• Daughter cells have identical DNA

• Meiosis
• Found only in sex cells
• Goes through cell division 2 times
• Final product are 4 sperms or for females 1 egg,
  3 polar bodies
