- A. Interpretation of Graph/Table Use graph key as guide A cell mitosis experiment in which the cells count is determined hourly over a 24 hour period is shown below: Growth curve: What conclusions can you draw about the process of mitosis over a 24-hour period? Lines: Individual Continuous Options Number of Cells.Hour Courtesy: www.inspiration.com 1. What conclusions can you draw about the process of cell mitosis over a 24-hour period;Choose all of the TRUE statements. Hint: 4 statements are true. Cytokinesis occurs the same way in both plant and animal cells. Sister chromatids are genetically identical. The term chromosome can be used to describe both chromosomes composed of one and two chromatids. Mitosis results in daughter cells that are genetically identical to the parent cell. All eukaryotic somatic cells are diploid. Cyclin dependent kinases are present but not active in cell cycle regulation without the presence of cyclin proteins. Chromosomes are always visible in the cell.PLEASE ANSWER THE FOLLOWING: 1. In figure 1 locate the mitotic zone or region of cell division. Next, identify mitotic stages visible in figure 2. Note down visible structural changes occurring at various stages of mitosis, namely: prophase (early and late) metaphase, anaphase (early and late) and telophase (early and late). 2. Point the specific mitotic stages that can be seen in the enlarged image of onion root tip cells undergoing cell division (figure 2). 3. Search for a diagrammatic illustration of the different stages of meiosis, examine/study carefully the changes occurring in each stage. Note how these stages assemble or differ from those of mitosis. 4. Then, summarize the structural changes occurring in each stage of mitosis and meiosis in a tabular form.
