Polyploidy occurs when an organism contains more than two sets of chromosome. One example of polyploidy is found in strawberries, which can have up to eight sets of chromosomes (octoploidy). It is expected that the size of the nucleus will be in direct relationship with the amount of DNA it contains, therefore, it is hypothesized that a strawberry with additional sets of chromosomes will have a larger nucleus. This will be tested using confocal microscopy in which the nucleus of cells from strawberries with different ploidies will be viewed and compared. Their cells will first be stained to cause the nuclei to fluoresce, and those cells will then be viewed simultaneously to make a direct comparison between the sizes of the nuclei.
