Prepared slides of a hyacinth root tip specimen wasalso examined with a microscope. C The number of cells per zone andthe total number of mitotic figures per zone (that is, cells thatare in prophase, metaphase, anaphase, or telophase) were recorded.Calculate the length of each zone (in mm and to two decimal places)and the Mitotic Index (M.I.) to one decimal place. Your lab manualshows how to determine the length of each zone in the root tip. 4marks
