A researcher studied onion root tip cells under a light microscope.
Cell A is in metaphase and can be approximated as a cylinder of length 35 μm35\text{ }\mu\text{m}35 μm and radius 12 μm12\text{ }\mu\text{m}12 μm.
Cell B is a spherical newly-formed daughter cell with a radius of 9.5 μm9.5\text{ }\mu\text{m}9.5 μm.
State the stage of mitosis during which sister chromatids are pulled to opposite poles of the cell.
Calculate the volume of the spherical cell B. Use the formula: volume of sphere=43πr3\text{volume of sphere} = \frac{4}{3}\pi r^3volume of sphere=34πr3. Give your answer in standard form to 2 significant figures, in μm3\mu\text{m}^3μm3.
Calculate the volume of cell A. Use the formula: volume of cylinder=πr2h\text{volume of cylinder} = \pi r^2 hvolume of cylinder=πr2h. Give your answer in standard form to 2 significant figures, in μm3\mu\text{m}^3μm3.
