Branches on the tree of life: the biology of plants
Clear graphic animation is used to describe the molecular level mechanisms of photosynthesis. Major plant groups include mosses, liverworts, ferns, horsetails, and the seed plants (gymnosperms and flowering plants). This..
Branches on the tree of life: the biology of protists
The term "protist" covers a wide range of microscopic organisms formerly clumped into "Kingdom Protista." New molecular analyses show that the protistan lines of evolution go so far back in time they can be considered a..
Branches on the tree of life: the biology of rotifers and nematodes
The diversity of rotifers is stunning, and this program shows many different species. Planktonic rotifers have special adaptations for open water life. Nematodes (round-worms) include a number of important human parasi..
Branches on the tree of life: the biology of sponges
Imagine an animal with no mouth, no digestive system, no excretory or circulatory organs, no brain nor nervous system, and no movement as an adult. In spite of their simple nature, sponges are actually one of the most f..
Branches on the tree of life: the biology of viruses
This program examines the discovery of viruses and their structure, how viruses are studied, how they infect their hosts and how they replicate. Details are provided on the T-4 bacteriophage and retroviruses such as HIV.
Exploring vernal pools
Seasonal temporary wetlands, commonly known as vernal pools, are a menagerie of diverse and fascinating organisms. This program contains two parts: a non-narrated observation section and a fully narrated instructional se..
