Module 03 Quiz Review Sheet Be sure to read and review the Powerpoints for Chapters 1-3 and 5 for the Quiz! Module 1 - Foundations of Microbiology and Lab Safety – Chapters 1 & 2: Know the various classes of microorganisms and unique features and characteristics of each: Bacteria- one of the two domains of prokaryotes; all medically important prokaryotes are in the domain Bacteria. bacteria are single-celled or noncellular spherical or spiral or rod-shaped organisms that reproduce by fission.

[ Protists are very small‚ singlecelled eukaryotes. ] 2) What types of environments do they typically inhabit? [ ] 3) Are bacteria and protists the same thing? Why or why not? [ ] 4) What is a prokaryote?[ ] 5) What is a eukaryote?[ ] 6) What has a more complicated structure: bacteria or protists?

The studies of Robert Hooke 1665 into a plant material would allow the determination of a pore like regular structure surrounded by a wall of which he called cells’ this in itself unbeknownst to him‚ was the discovery of the fundamental unit of all living things. In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell.’ Over 150 years later this can be regarded as one of the most familiar and important facts within the

classification that divides cellular life forms into archaea‚ bacteria‚ and eukaryote domains. It emphasizes the separation of prokaryotes into two groups‚ called Bacteria and Archaea. These two groups and eukaryotes each came from separate ancestors with poorly developed genetic make-ups. This classification system recognizes the fundamental divide between the two prokaryotic groups. Archaea appear to be more closely related to eukaryotes than they are to prokaryotic bacteria. The Archaea Domain consists

Plants‚ also called green plants‚ are multicellular eukaryotes of the kingdom Plantae. They form a clade that includes the flowering plants‚ conifers and other gymnosperms‚ ferns‚ clubmosses‚ hornworts‚ liverworts‚ mosses and the green algae. In biology‚ kingdom (Latin: regnum‚ pl. regna) is the second highest taxonomic rank below domain. Kingdoms are divided into smaller groups called phyla. Traditionally‚ textbooks from the United States used a system of six kingdoms. A fungus (/ˈfʌŋɡəs/; plural:

1. Describe the structure of a generalized eukaryotic plant cell. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Plants are unique among the eukaryotes. The interiors of plant cells‚ like all eukaryotic cells‚ contain numerous organelles‚ which are membrane bounded structures that close off compartments within which multiple biochemical processes can proceed simultaneously and independently. The cell membrane

Origin of Life 1. The four stages of hypothesis for the origin of life on Earth by chemical evolution is * Abiotic synthesis of small organic molecules * The joining of small molecules into macromolecules * Packaging of these molecules into protobionts * The origin of self replicating molecules that made inheritance possible. 2. A.I. Oparin‚ and J.B.S. Haldane hypothesized a reducing environment. Stanley Miller and Harold Urey did lab experiments that showed that the abiotic

Choose 2 pieces of evidence (that we learned about in class) and explain how they support the theory that eukaryotes evolved from prokaryotes. Eukaryotes and Prokaryotes differ in many ways‚ although‚ there are three major differences. One of these differences is that Prokaryotes do not contain a nucleus; Eukaryotes contain a nucleus. The second major differences is that Prokaryotic cells are
