Mitosis Magic }

As we all know, adult humans are not the same size as babies. Why is that?

A cut on your skin “disappears” after a few days. How does that happen?

Mitosis!

Check out the video below for an introduction to this essential process of living organisms.

Cell Division

Cell reproduction is also called cell division. Before we begin looking at cell division - we need to review what cells are made of.

Watch the presentation below to review DNA and discover Mitosis.

Phases of Mitosis

The phases of mitosis are prophase, prometaphase, metaphase, anaphase, and telophase. The last step of the cell cycle is cytokinesis. Click on each phase below to learn more. 

Events in Mitosis and Cytokinesis

Click through the notes below on the stages/events of Mitosis.

The video below will walk you through the steps one more time. Can you tell these are important?

Below is a summary graphic of the events of mitosis and cytokinesis. Make sure you know all the phases in order!

Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis

Do plant and animal cells reproduce the same?

While most of the steps are identical, there are two main differences between how plant and animal cells reproduce:

  1. A cell plate forms in a plant cell, while the cell cleaves (pinches) in animal cells during cytokinesis.
  2. Plant cells do not have centrioles. They have microtubules instead.

Mitosis Challenge and Before You Go

Practice Time! Use the knowledge you learned from the lesson to complete the practice activities below.

Before You Go - You Need To Know

The following key points are from the explore section of the lesson. You must know the following information before moving to the next lesson. This is just a summary of the key points.

  • What are the two phases of the cell cycle?
    • Interphase and Mitosis
  • What is the order of the phases of mitosis?
    • Prophase, Prometaphase, Metaphase, Anaphase, Telophase
  • What happens in cytokinesis?
    • The cytoplasm divides and the cell becomes two cells.
