AP Biology Plane and Symmetry of Cell Division 1) Different Planes – Figure 1 a) Cell division in the same plane = produce a single file of cell b) Cell division in three planes = generate a cube 2) Asymmetrical cell division = unequal distribution of cytoplasm during mitosis a) Significance = It can result in the formation of epidermal guard cells (the cells that border stomata) 3) The plane where a cell divides is determined by cytoskeleton during late interphase – more specifically preprophase band – Figure 2
