A Tour of the Cell

Paul Andersen takes you on a tour of the cell. He starts by explaining the difference between prokaryotic and eukaryotic cells. He also explains why cells are small but not infinitely small. He also explains how the organelles work together in a similar fashion.

The Cell Cycle (and cancer) [Updated]

Explore the cell cycle with the Amoeba Sisters and an important example of when it is not controlled: cancer. We have an Unlectured resource for this topic: Expand video details for table of contents. 👇 Video also mentions cell cycle checkpoints and cell cycle control.

Table of Contents:
1:00 Cell Growth and Cell Reproduction
1:42 Cancer (explaining uncontrolled cell growth)
3:27 Cell Cycle
5:26 Cell Cycle Checkpoints
6:48 Cell Cycle Regulation
8:16 G0 Phase of Cell Cycle

Vocabulary in this video includes the words apoptosis, G1, S, G2, mitosis, and cytokinesis. Positive regulator proteins such as cyclins and cyclin dependent kinases are briefly mentioned as well as a negative regulator protein p53.

Positive and negative regulation reference regarding cyclin types and cyclin rise/fall areas [in humans]:

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky's certification and experience in teaching science at the high school level. Pinky's teacher certification is in grades 4-8 science and 8-12 composite science (encompassing biology, chemistry, and physics). Amoeba Sisters videos only cover concepts that Pinky is certified to teach, and they focus on her specialty: secondary life science. For more information about The Amoeba Sisters, visit:

We cover the basics in biology concepts at the secondary level. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook:

Cell Biology: How Do Cells Make Decisions?

The UCSF community honored J. Michael Bishop's 11-year tenure as chancellor of UCSF with an all-day symposium addressing vexing biomedical issues at the Mission Bay campus on June 7. The event focused on four topics: malaria, cell biology, cancer and neurosciences.

As chancellor, Bishop, MD, a Nobel laureate, led UCSF through one of its most expansive periods of growth and achievement, including development of the Mission Bay campus.

In this segment of the symposium, titled Cell Biology: How Do Cells Make Decisions?, the moderator is Marc Kirschner, PhD, John Franklin Enders University Professor of Systems Biology, Department of Systems Biology, Harvard University; the speaker is Richard Losick, PhD, Maria Moors Cabot Professor of Biology, Department of Molecular and Cellular Biology, Harvard University; and panelists are Hana El Samad, assistant professor, Biochemistry & Biophysics, UC Berkeley/UCSF Graduate Group in Bioengineering; and Jonathan Weissman, PhD, professor of Cellular and Molecular Pharmacology and of Biochemistry and Biophysics at UCSF.

Biology: Cell Transport

How do things move across the cell membrane, either in or out? This animation shows two broad categories of how things pass into or out of a cell: passive transport and active transport.

Passive transport is automatic; no input of energy is required. For example, diffusion is a passive process in which particles move either into or out of the cell from an area of higher concentration to an area of lower concentration.

Active transport, on the other hand, is when particles move from an area of lower concentration to an area of higher concentration. Because particles are moving against the concentration gradient, energy is required.

After viewing this video, the viewer will be able to:
• List the two broad categories of cell transport
• Describe the difference between active and passive transport.
