mitosis

• I Peed Myself And Then Cried.
• Interphase is when the cell grows and duplcates its DNA.
• Prophase is when DNA condenses and the nuclear membrane breaks down.
• Metaphase is when chromosomes line up on the middle of the cell.
• Anaphase is when the spindle fibres split the chromosomes down the centre and pull one chromatid to either side of the cell.
• Telophase is when new membranes form around the chromosomes.
• Cytokinesis is when the cytoplasm divides to form two daughter cells.
• Diploid cells have 2 sets of cromosomes, one from each parent. (46)
• Haploid cells have one set of chromosomes. (23)
• Asexual reproduction is the production of genetically identical offspring from a single parent. Eg. potatoes and strawberries.
• Asexual Reproduction:

  Pros —

  • Faster than sexual.

  • More energy efficient.

  Cons —

  • No genetic variation so disease affects the whole population.

  • Population vulnerable to changes in conditions.
• Mitosis is required for:

  • Growth — production of new cells.

  • Repair — replace damaged/dead cells.

  • Asexual reproduction — genetically identical clones
• Cancer is when cells uncontrollably divide rapidly and produce growing lumps on the body called tumours.
