A cytologist studied cultured mammalian cells undergoing division under a confocal microscope.
Cell P is in metaphase and can be approximated as a cylinder of length 48 μm48\text{ }\mu\text{m}48 μm and radius 13 μm13\text{ }\mu\text{m}13 μm.
Cell Q is a spherical newly-formed daughter cell in the G1 phase with a radius of 7.8 μm7.8\text{ }\mu\text{m}7.8 μm.
State the stage of mitosis during which chromosomes align along the equator of the cell.
Calculate the volume of the spherical cell Q. Use the formula:
volume of sphere=43πr3 \text{volume of sphere} = \frac{4}{3}\pi r^3 volume of sphere=34πr3Give your answer in standard form to 2 significant figures, in μm3\mu\text{m}^3μm3.
Calculate the volume of cell P. Use the formula:
volume of cylinder=πr2h \text{volume of cylinder} = \pi r^2 h volume of cylinder=πr2hGive your answer in standard form to 2 significant figures, in μm3\mu\text{m}^3μm3.
