The physiological traits that cause our bodies to age are examined in a short, animated video.

Why are Henrietta Lacks' cells immortal? The answer is that no one really knows. But much has been learned because they are. Check out this video that introduces some of these remarkable discoveries.

Is it possible to grow a human bone outside the body? Begin by taking a look at how bones grow naturally within the human body, the elements that make bones strong and functional, methods currently used to replace bones, and finally, how...

This resource offers a series of film clips created by scientists studying this model organism. There are movies of embryos, larvae and adults and fascinating techniques. Great to supplement advanced study of cell biology and development.

The inner workings of human cells are shown in this amazing animation focusing on mitochondria. The movie is accompanied by music. [2:09]

Understand that cell size is limited by volume to surface area ratio in this video. Learn that if cells become too big it cannot take in nutrients and get rid of waste fast enough. [8:55]

Video tutorial provides an overview of DNA transcription, translation, and replication during mitosis and meiosis while also teaching about chromosomes, chromatids, and chromatin. [18:23]

Video lecture provides a discussion on apoptosis (programed cell death) and how it is different from cell death by injury. Also, delves into its role in development and body maintenance. [10:47]

An in-depth look at the different types of cells, including prokaryotes and eukaryotes. Also includes a deeper discussion of each organelle and its contribution to the cell's life. [14:16]

A sometimes humorous look at plant and animal eukaryotic cells. Learn about specialization and compartmentalization in cell biology through this YouTube video. [9:16]

This tutorial reviews the principles of the cell theory. The cell theory states that all organisms are made of cells. These cells are the smallest and basic unit of life. And finally, cells can only come from other cells.

An organized directory showcasing cell and molecular animations for use in high school biology classrooms.

Students watch a video that follows blood cells as they are propelled through a blood vessel toward a child's injured knee. See the process of tissue repair through cell signals.
