✏️ Part 2: Short Answers

5. Explain why a cell needs to grow and increase its sub-cellular structures before dividing.

6. Complete the sentences about cell division:

During the cell cycle, the genetic material is _____________ and then divided into two _____________ cells.

Finally, the _____________ and cell _____________ divide to form two identical cells.

7. Describe two situations where mitosis is important in multicellular organisms.

🔬 Part 3: Application

8. A student observes cells under a microscope and notices that some cells have chromosomes lined up in the centre, whilst others have chromosomes being pulled apart. Explain what is happening in these cells.
