Explain what mitosis is and its different stages.

Clearly presents the steps in meiosis and mitosis with each step accompanied by an illustrated fact card.

The differences between mitosis and meiosis are explained in this resource. Includes labeled diagrams showing what happens during each and a chart giving an overview of their differences.

Understand the life cycle of a eukaryotic cell.

An informational text about mitosis and its role in reproduction. A question sheet is available to help students build skills in reading comprehension.

Has explanations, illustrations, and a Quick Time movie to download. Also contains practice test questions that are answered online.

These microscope activities provide students with lots to explore. Activities include the characteristics of living things, math in science, cell biology, genetics, physiology, and mitosis.

Describes the structure and functions of centrioles within a cell.

Nondisjunction is when homologous chromosomes or sister chromatids fail to separate normally during cell division. What it is and how this happens are explained here, as well as what can cause it and what impact it has on human health.
