Practice identifying the phases of mitosis in the root tip of an onion,

Onion root tip image to use in completing Table 1

pg 71 - no Qs - need beads to manipulate Be sure you can step through the beading exercise to demonstrate mitosis and meiosis as you will be asked to demonstrate it for 30 lab skill points.

If you feel good about your ability to distinguish between the processes of mitosis and meiosis with the beads, this might be a good time to ask about being graded on this skill (30 pts).

Staining an onion root specimen and observing with microscope Lab skills graded - 20 pts

- instructions continued from previous page Locate as many stages of mitosis as you can find. Try to confirm the amount of chromosomes of the onion which is sixteen.

Table 1 - 17 pts Use the image of the root tip above to complete Time for 100% is given ( about 15 hrs interphase = 900 mins + about 83 mins mitosis = 983 mins) Note: Your counts may not match this time exactly because you are only counting a small portion of the root tip.

What is the basic shape of the cells observed?

How many nucleoli can you observe in each nucleus? (answer with a number)

What happens to the nuclear membrane during prophase?

What happens to the chromosomes during anaphase?

What happens to the nuclear material in late telophase?
