Evolution of Plantae
Today we examined specimens that represented Bryophytes and Tracheophytes. Tracheophytes included sphenophyta (horsetail) , pterophyta (fern), spermophyta (seed plants) . Of the spermophyta, we looked at gymnosperm and angiosperm samples. We also observed a sundew in action (Drosera rotundifolia) after a few students captured a small spider and let it walk on the sundew. Images of Shelob from Lord of the Rings comes to mind.... We also passed around a fuzzy and soft Stachys byzantina leaf: or lamb's ear.
Our notes today were the Kingdom Plantae notes here on alternation of Generation and the evolution of plants.
