1. MITOSIS

• What does nucleus contain and in what form?

  Nuclues contain genetic information and in the form of chromosomes.
• What are chromosomes?

  Chromosomes are coiled up lengths of DNA molecules.
• Every human cell contains .. chromosomes


  46 chromosomes
• Egg and sperm cells contain .. chromosomes


  23 chromosomes
• What are diploid cells?


  Cells with 2 sets of chromosomes (46 in total)
• What are haploid cells?


  Cells with 1 set of chromosomes (23 in total)
• What is mitosis?

  A type of cell divison to create new cells.
• What does mitosis produce?

  Produces 2 daughter cells, each with identical sets of chromosomes as the parent cells
• What is the cell cycle important for?

  Growth, Repair and asexual reproduction for plants
• What are the 3 processes in the cell cycle?

  Interphase, Mitosis and cytokinesis
• What is the process of interphase?


  In a cell that's not dividing, the DNA is spread out in long strings. Before it divides, the cell grows and duplicates its DNA and doubles the amount of subcellular structures.
• In interphase, what is there only one copy of for each new cell?

  DNA - it's copied and forms X-shaped chromosomes. Each "arm" is an exact duplicate. Each arm is a chromatid
• What are the 4 processes involved in mitosis?

  PMAT- Prophase, Metaphase, Anaphase, and Telophase
• What happens in prophase?

  Chromosomes condense, getting shorter and fatter. Membrane around the nucleus breaks down and chromosomes lie free in the cytoplasm
• What happens in metaphase?

  Chromosomes line up at the centre of the cell.
• What happens in anaphase?

  Spindle fibers pull the chromosomes apart and chromatids are then pulled to opposite ends of the cell.
• What happens in telophase?

  Membranes form around each of the sets of chromosomes and now there are 2 nuclei visible, each for the 2 new daughter cells.
• What is cytokinesis?


  The process of cell division is finished.
• What happens in cytokinesis?


  The cell has produced 2 new daughter cells. Each daughter cell is genetically identical diploid cells and to the parent cell.
• How do you calculate the final number of cells?
