    • 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?
      2^n
