• Organelle


  A specialized sub-unit within a cell that has a specific function such as mitochondrion, golgi bodies, lysoseine, vacuole, etc.
• Karyokinesis


  Division of the nucleus
• Cytokinesis


  Division of the cytoplasm
• Diploid number (2N)


  The cell contains two sets of chromosomes, half from the father and another half from the mother .
• The cell cycle has two main stages:

  • Interphase
  • Mitotic phase or M phase
• Interphase is divided into 3 sub-stages:

  • Gap 1
  • Synthesis (S phase)
  • Gap 2
• Mitotic phase or m phase is divided into 4 sub stage ^

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase
• What happens in gap 1?

  Growth
• What happens in Synthesis or s phase?

  Growth and dna replication
• What happens in gap 2?

  Final preparations for cell division
• Interphase

  Cell resting and preparation phase
• M phase

  Cell division phase
• Prophase

  Chromosomes are duplicated and visible
• Metaphase

  Chromosomes are align at the equatorial plate
• Anaphase

  Sister chromatids separate and move toward the opposite poles
• Telephase/ cytokinesis
