BIOL 211 Lecture 1: Chapter 1 and 3
Document Summary
The genus (capitalized) and then the specific epithet (species name) Bacteria (cell wall contain a protein - carbohydrate complex called peptidoglycan) Enclosed in cell walls that are largely composed of a carbohydrate and a protein complex called peptidoglycan. Use organic chemicals for nutrition - from dead or living organisms. Many can swim using appendages called flagella. Archaea (cells walls, if present, lack peptidoglycan) Distinct nucleus and surrounded by a special envelope called the nuclear membrane. True fungi have cell walls composed of chitin. Absorb solutions of organic material from their environment. Use light as source of energy and co2 to produce sugars. So small only seen with electron microscope. Core made out of only one type of nucleic acid, dna or rna and surrounded by a protein coat and sometimes surrounded by a lipid envelope. Can reproduce only by using cellular machinery of other organisms. Fungi (unicellular yeasts, multicellular molds, and mushrooms) Plants (mosses, ferns, conifers, and flowering plants)
