  1. How do cells grow and Divide? Chapter 2 section 3

  2. Why do they need to divide • 1. To make more • 2. They also need to be efficient in getting materials around the cell • 3. If they are too large then the cell will not function efficiently.

  3. Cell division • Single cell- divide into two identical daughter cells • Multi-cellular- also divide into two daughter cells when making new cells for growth or repair

  4. Mitosis • 1. The cell’s nucleus divides • The nucleus contains DNA • Used to code for all the genes in the organism • Complex molecule consisting of three parts • Found in the chromosomes

  5. Interphase • The cell copies its DNA and gets ready to divide

  6. Prophase • Mitosis begins • Short, compact chromosomes become visible • Nuclear membrane dissolves

  7. Metaphase • Pairs of chromosomes line up at the center of the cell

  8. Anaphase • The chromosomes separate • The two halves move to opposite sides of the cell

  9. Telophase • Two new daughter cells are made • Identical to the original • Nuclear membrane appears
