BIOL 117 Study Guide - Midterm Guide: Paraphyly, Unikont, Monophyly
Document Summary
A foram has an external shell: many protists contain cells that have cell walls. Chitin: fungi are composed of networks of filaments known as hyphae. Spores are formed in both sexual and asexual reproduction. Meiosis: in most cases, fungi phylogenies based on dna show monoplyletic groups based on reproductive structures. We studied four of these groups in class. Fill in the table below with the characteristics of each: Zygosporangium: spore structure formed when two individuals meet and hyphae yoke together. Basidia form at the end of hyphae and produce spores. Lecture 6 the diversity of life: animals. Choanoflagellates are similar to the cells that make up the bodies of sponges, colonial evolution. They have one opening where food goes in and bile comes out: a coelom is a fluid-filled body cavity. Protosomes zygote divides in a spiral which created differently sized cells, gastrulation creates the mouth, coelom forms separate from the gut.
