1. The lab experiment involved using pop beads to simulate the phases of mitosis and meiosis in plant cell division. Students observed onion root tip cells under a microscope to identify the phases of mitosis. 2. Data was collected on the number of cells observed in each phase of mitosis and the percentage of time a cell spends in each phase was calculated. A line graph of the results was made. 3. Key differences between mitosis and meiosis were identified through the pop bead simulations and microscope observations, such as the number of resulting cells and chromosomes after each type of cell division.
