What is the average time an onion root tip cell takes to complete a cell cycle?

It takes about 24 hours, or one-thousand, four-hundred and forty minutes, for an onion roottip cell to complete the cell cycle.

Furthermore, in what stage of the cell cycle does a typical onion root tip meristem cell spend most of its time?

It spends the most time in Interphase.

Also, how many cells are in an onion root tip during interphase? Onion Root Tips Mitosis

Interphase Prophase
Number of cells 20 10
Percent of cells 55.6% 27.8%

Just so, how much time is spent in each phase of the cell cycle?

Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.

Why are onion root tips a good choice for viewing cells in different stages of the cell cycle?

These regions of growth are good for studying the cell cycle because at any given time, you can find cells that are undergoing mitosis. In order to examine cells in the tip of an onion root, a thin slice of the root is placed onto a microscope slide and stained so the chromosomes will be visible.
