cell division

• what do all multicellular eukaryotic cells need

  they constantly need new cells, meaning they need to constantly divide
• why do these cells need new cells

  growth, development and repair
• what organisms constantly need to be doing cell division especially

  younger organisms as they haven't fully developed and cell division helps them grow
• what are new cells also needed for

  to replace old ones
• what is an example of cells that constantly need replacing

  skin cells - old ones shed and new ones replaces them
• what organisms constantly need their cells replaced especially

  older organisms
• what happens when a cell isn't dividing

  the DNA spreads out into long strings
• what happens to the DNA when preparing for division

  the DNA condenses into chromosomes
• what happens as cells continue to prepare for division

  each chromosome is duplicated and attached to the original
