This edition: Secrets of the Cell
What is a cell and why is it crucial to the understanding of life processes? Dr. Dwayne Simmons describes how a vast universe of cells works together to form living beings. For example, a football player’s separate populations of cells in his ears and brain enable him to focus on important sounds amid the din of background noise from the crowd.
In the next segment, Dr. Robert Heath discusses the role of membranes in cells and the importance of molecular movements in plants.
Finally, the program compares wholly different types of cells: the cells of prokaryotes versus those of eukaryotes. Dr. Dennis Focht tells why bacteria are self-contained living cells that envelop and permeate almost everything around us. He also describes the incredibly complex world of prokaryotes. Included in the program are discussions of the various organelles found in eukaryotic cells.
