are miniature tubes that act as the skeleton of the cell, just like our skeleton holds us together. In mitosis, the microtubules rearrange themselves into spindle fibers that stretch between the centrioles and attach to the chromosomes to move them around, as you will see in the diagrams contained in the mitosis section.

Labs. Have students do this "Observing Mitosis Lab" using prepared slides of onion (Allium) root tips. Another good "Stages of Mitosis" lab using onion root tip slides.

Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. The cells involved with human reproduction, however, carry only half after division occurs. In this step-by-step explanation, learn about mitosis and meiosis, the two types of cell division.

For example; for years, I have used the traditional "hands-on lab" of pipe cleaners to teach mitosis and cell division.

Note: Plant cells are often shaped like boxes because they are surrounded by a cell wall; at the end of mitosis, the cell plate divides the two daughter cells. Animal cells take a variety of different shapes; at the end of mitosis, a neck forms to separate the two daughter cells.

Context
This lesson is best done after students have at least read about mitosis and meiosis, and/or seen a film, video, or online animation showing these two processes. Mitosis may have been studied earlier in the context of cell studies, or simple cell reproduction. But after an introduction to meiosis, where they've had a chance to get the essential ideas, along with distinctions from mitosis, and the significance of meiosis, have them do this lab. Most students discover that their understanding of critical aspects of meiosis are often not as clear as they should be. This lab will show them the way!

Mitosis is the first of these studied in this lab

Meiosis is a process that starts with one diploid cell and creates four haploid cells. Meiosis is similar to mitosis and must have the cell's DNA replicate before it can begin. This creates chromosomes that are made up of two sister chromatids connected by a centromere. Unlike mitosis, meiosis requires two rounds of division in order to get half the number of chromosomes into all of the daughter cells.

RATIONALE
When I taught college prep biology, I introduced mitosis as a fundamental part of basic cell reproduction (in my Reproduction unit). We observed video clips in time-lapse so they could see the whole process of mitosis as an orderly process of nuclear duplication and separation (followed by cytoplasmic division or cytokinesis). Then they searched for and drew key phases of mitosis in onion root tips.

LabBench Activity Mitosis and Meiosis

In meiosis, replicated homologous chromosomes pair off during the first division, then these separate from each other, assuring that one member of each pair of chromosomes goes into two separate cells. Replicates separate in the second division. In mitosis, there is no pairing of replicated homologous chromosomes.
