Have you scraped your skin or bit your lips and within days the wound is healed?  What's happening?
 - The cells in animals and plants are constantly dividing
 - It is this constant division that leads to new cells
 - Cell division is a unique feature of living organisms
 - Cells divide to replace old, dead or damaged cells, for growth

The type of cell division that occurs, depends on the type of cells. In this video, I'm trying to observe MITOSIS = cell duplication in the roots of garlic
  ○ The process by which non-reproductive, think egg and sperm, cells divide
  ○ Somatic cells make up most of the cells in the skin, muscles, lungs, hair and guts
 - Mitosis
  ○ Creates two genetically identical daughter cells
  ○ Each daughter cell has the same chromosomes and DNA as the parent cell & are diploid
  ○ In general 6 phases of mitosis result in new diploid cells
   § Interphase
    □ Where cells spend most of their time
    □ It's the get ready with me phase (pick out the clothes, accessories, make-up, etc.,)
     ® Gather nutrients & energy
     ® Parent cell is making a copy of its DNA to share equally b/w the two daughter cells
   § Prophase
    □ Chromosomes  of the parent cell shorten, looking like "X" under the microscope
     
   § Metaphase
    □ The chromosomes start forming a line along the equatorial plane
   § Anaphase
    □ Each sister chromatid (each duplicated chromosome has two chromatids) separates and starts moving to opposite ends of the cell
   § Telophase
    □ Chromosomes arrive at the ends/poles of the cell
    □ The new membrane that has copies of the original forms around the chromosomes
   § Cytokinesis 
    □ Physical splitting of the parent cell into TWO identical daughters

 - Time of day, temperature and chemicals influence mitosis and the duration of mitosis, from interphase to cytokinesis depends on the kind of cell and the species of organism
