Biology Year 9

• At the Prophase Cells grow Chromosomes and Organelles are replicated.
• At the Metaphase mitosis occurs, nuclear membrane breaks down, chromosomes line up in the centre of the cell
• At the Anaphase chromosones are pulled to opposite ends and the nucleus divides.
• During the Interphase the cell grows and makes a copy of it's DNA.
• During the Telephase the Cell Membrane, Nucleus and Cytoplasm divide.
• Cell division allows cells to reproduce or duplicate themselves if they have been damaged or destroyed.
• Define Organ

  A group of tissues that work together to perform a specific function in an organism
• Define Magnification

  The amount of times you need to expand something in size.
• What is the Calculation for Magnification?

  Image size ÷ Real image size
• Osmosis


  The movement of water molecules through a semi-permeable membrane
