Organelles in the Cytoplasm
For the longest time, scientists couldn't imagine how simple cells managed to perform so many amazing tasks in living organisms. It turns out that cells aren't simple at all. Much like complex organisms with organs that perform specific tasks, cells have many organelles that keep them functioning properly. Explore some of a cell's most important structures in this video segment from An Introduction to the Living Cell. Closed captioning included. Run time 06:06.

Immune Cells in Action
In this video segment from The Secret of Life, you'll look through a microscope at a virus attacking a cell. Viruses continue to replicate until they break apart the host cell and start spreading throughout the body, destroying healthy cells along the way. You'll learn how the immune system overpowers a virus with white blood cells and creates the antibodies that kill the same types of viruses quickly if they return. Closed captioning included. Run time 01:40.

Dengue Virus
This visualization adapted from the University of Massachusetts Medical School represents the process by which a dengue virus releases its genetic contents inside a host cell, allowing viral replication. The key players are proteins found on the viral surface called envelope proteins, which change their structure when the virus is endocytosed, or taken inside the cell. This structural change enables the viral membrane to fuse with the endosomal membrane, and the virus' RNA to enter the cytoplasm
