Document Summary

Biol1f90 (cid:1005)(cid:1004) phyla of land plants and how they"re grouped together. Liverworts, hornworts, mosses, lycophytes, pteridophytes, cycads, gingkos, conifers, Gymnosperms: cycads, gingkos, conifer, gnetophytes seeded vascular plants. Omasum reticulum and rumen are esophageal pouches known as the forestomach in herbivores used to help digest cellulose. The rumen and reticulum have cellulose digesting enzymes, omasum absorbs some water and salts from the food. Abomasum is the true stomach, contains enzymes and acids to break down food, eventually releases the chyme into the intestines. Apomorphy: derived traits, more recently evolved, further away from the common ancestor. Archaea are relatives of bacteria with slight modifications evolved from a common ancestor. Archaea more closely related to eukarya than bacteria archaea engulfed a proteobacteria and a cyanobacteria to develop eukaryotes. Archaea are often (but not always) extremophiles love extreme environments. Bacteria are found in more moderate conditions.
