All About Symbiosis
February 19 @ 4:00 pm - 5:30 pm
An event every week that begins at 4:00pm on Tuesday, repeating until March 12, 2019
AT LIFELONG (4 sessions, $40)
Description: Symbiosis (literally, “living together”) is a fundamental characteristic of life. It is found at all levels of the biological world, including lichens growing on barren rock surfaces and bacteria colonizing plant roots and animal intestines. Even the mitochondria that help to power every cell in our bodies were originally bacteria which established a mutually beneficial symbiotic association within a primitive host cell about 1.5 billon years ago. In this course, we will discuss these and a variety of other symbiotic associations, such as nitrogen-fixing bacteria in plant roots and the vast number of microbes that inhabit the human gut. Our goal is to appreciate and understand the biological importance of symbiosis by examining how symbiotic associations function and how they may have come about. No particular scientific knowledge is required.
Instructor: Bill Ghiorse is Professor Emeritus of Microbiology at Cornell University. He has done extensive research in environmental microbiology and taught general microbiology, including lectures on medical microbiology for more than 37 years. He believes that everyone should know more about the microbes in their life and the many positive (and few negative) impacts they have on human activities.
