Unformatted text preview: I prepared this as a general guide for studying. There are also 3 sample questions, easy, medium and challenging. Below that is a list of what you need to know from the images. No other images will be on the exam, though the concepts they demonstrate may be. Dr. Jasper LEARNING OBJECTIVES – Ch 1 • List and describe the six kingdoms of living things. • Bacteria – prokaryotes (no nucleus) • Archaea – prokaryotes (no nucleus) • Protista – not a true grouping; made of a lot of taxonomic units (kingdoms) but grouped together for convenience; mostly single-celled organisms; algae, kelps, sargasm • Fungi – mushroom, mildew, mold from fridge, puff balls, morrels • Plantae – food from flowers & plants • Animalia – most are invertebrates • Understand the five properties shared by all living things. • All living things share certain properties as a result of billions of years of evolution from a common ancestor. • 1) Cellular organization – all living things are made of cells. • 2) Metabolism – need energy; take material & convert it into useable energy • 3) Homeostasis – maintain body; keep internal composition of a cell different from its external medium; “steady state”; organism keeps correcting itself to reach this state • 4) Growth and reproduction – getting larger; reproduce sexually or asexually • 5) A genetic system based on DNA, which transmits characteristics from parent to offspring in a process called heredity – living organisms have RNA (important in duplication of DNA & in making proteins); DNA – where msgs are encoded & cause an organism to look the way it does • Understand the levels of hierarchical organization of the living world. • Cellular level – molecular, organelle, cell (smallest living level of organization) • Organismal level – tissues, organs, organ systems • Population level – populations (one particular area at a particular time), species, community, ecosystem (community & abiotic factors – energy flow, nutrients, water, soil, temperature, other nonliving components) • Understand the concepts behind the five major themes used to organize the study of biology in this text: evolution, flow of energy, coevolution, function and structure, homeostasis. • 1) Evolution is the change in gene frequency (of a population, not in an individual – one person growing is not evolution) over time that may result in a new species....
