Meiosis Lab
Lab #3: Mitosis and Meiosis
To investigate the processes of mitosis and meiosis. Cells come from previous existing cells. New cells are formed by cell division, which involves karyokinesis and cytokinesis. Karyokinesis is the division of the cell's nucleus and cytokinesis is the division of the cytoplasm. Mitosis and meiosis are the two types of nuclear division. Mitosis results in body cells: the formation of an adult organism from a fertilized egg, regeneration, asexual reproduction, and maintenance or repair of body parts. All of this happens through mitotic cell division. Meiosis results in formation of gametes (in animals) or spores (in plants). Their cells have half the chromosome number of the parent cell. Meristems are …show more content…
Roots consist of different regions. The root cap functions in protection, apical meristem is the region that contains the highest percentage of cells undergoing mitosis, region of elongation is the area in which growth occurs, and the region of maturation is where root hairs develop and where cells differentiate to become tissues. Whitefish blastula is used to study cell division. The egg is fertilized, then it begins to divide and nuclear division after nuclear division follows. The cell cycle is approximately 24 hours for cells in activity dividing onion root tips. The relative length of time that a cell spends in the various stages of cell division. You look at the slides of onion root tips/whitefish blastula and you find the meristematic region with 10x and 40x magnification of a microscope. Then you identify one cell that represents each phase and draw them. To find out the relative length of time that a cell spends in the various stages of cell division. To investigate the processes of mitosis and meiosis. Cells come from previous existing cells. New cells are formed by cell division, which involves karyokinesis and cytokinesis. Karyokinesis is the division of the cell's
