Voyager Lecture Series: Jerry Harris
The Making of Plants
Tuesday May 25th @ 7:30pm ($15/$10)
Tickets are $15 for adults and $10 for students and children.
Plants used to live only in water millions of years ago. In fact, they didn’t even look like today’s plants…plants’ ancestors were algae. Eventually, they evolved to find their way onto land and make use of a completely new environment. Even though moving to land had its perks, it also had its problems. Within their cells, plants had to figure out how to regulate the water being lost to the air. For this purpose, the waxy covering on top of leaves, called a cuticle, evolved. This is why leaves are shiny, waxy, and it’s why water just rolls off. Human skin is actually quite similar. The oils on our skin help us retain internal water and defend against pathogens (and keep the epidermis flexible).
Plants had to figure out how to obtain resources from soil and air. There were no vessels that could carry water throughout the plant… so eventually they developed vascular tissue to transport water/sugar within the plant. Plants had to figure out how to support their body up in the air because algae had no such structures. This gave way to the specialization of the root system and the shoot system.
At 7:30pm on May 25th, the Voyager Lecture Series continues with Jerry Harris showing us how plants became the life support and beauty of the modern world.
Jerry D. Harris
Director of Paleontology, Science Department, Dixie State University
Dr. Jerry Harris was born at a very early age in Chicago, Illinois. Shortly thereafter, he became enamored with dinosaurs, and his continued fascination with them proves that he’s never quite grown up completely. With a few hiccups along the way, and by continually moving across the country, he has earned B.A., M.S., and Ph.D. degrees in the geosciences, focusing on vertebrate paleontology. He has worked at the Denver Museum of Nature and Science and the New Mexico Museum of Natural History and Science; he is currently the Director of Paleontology and a Professor of Geology at Dixie State University, and is the scientific advisor to the St. George Dinosaur Discovery Site in St. George.
