If mitosis were to be uncontrolled, the cells would keep dividing and increases the overall number What would happen if mitosis were uncontrolled? This makes sense because this is the longest phase.Īs a cell grows, what happens to its surface area-to-volume ratio (hint: think of a balloon beingīlown up)? How does this ratio change with respect to cell division?Īs a cell grows, the surface area to volume ratio decreases, when the surface area cannot support Most of the cells were in the interphase. In what stage were most of the onion root tip cells? Does this make sense? Label the arrows in the slide image with the appropriate stage of the cell cycle.Stage Number of Cells in Stage Total Number of Cells Number of Hours Spent in Stage In the onion root tip is 24 hours, I predict interphase will take closer to 20 My supporting evidence for this claim, is that interphase is the longest Predictions My prediction is that interphase will take the longest time of the cell cycle for approximately 20 hours, and mitotic phase will take 4 hours. A drug to improve the immune function could help this.ĮXPERIMENT 1: OBSERVATION OF MITOSIS IN A PLANT CELL Data Tables A drug that could kill the HPV virus could help prevent the growth of cancer cellsĪ weakened immune system could make someone more susceptible to bacteria and virus entering the body results in growth of toxic cells. Investigate two known causes for cancerĪnd use this knowledge to invent a drug that would prevent the growth of cancer cells.Īn HPV infection is from a strain of the Human Papillomavirus which may lead to cervical cancer. Cancer is a disease related to uncontrolled cell division.For plant cells, vesicles help create a cell plate, creating a cell wall to divide the cell into.During cytokinesis for animal cells, the cell pinches in half to create two daughter cells.Plant cells have cell walls, cytokinesis in animal cells does not need to create a cell wall.How does mitosis differ in plant cells versus animal cells?Īnaphase is similar in both plant and animal cells.Mitosis ends with two identical diploid cells.Meiosis results with four non-identical cells (gametes) haploid.Cytokinesis follows both mitosis and meiosis.Meiosis creates gametes (sperm and egg cells).O Both mitosis and meiosis go through PMAT (prophase, metaphase, anaphase, telophase) O Interphase occurs before both, duplicating chromosomes before division Both start with diploid (2 sets of chromosomes).Both mitosis and meiosis are involved in making new cells.Compare and contrast mitosis and meiosis.Chromosomes are comprised of a molecule of DNA (deoxyribonucleic acid) and a protein
