Chapter 16 Vocabulary
Prokaryote: Group of organisms that lack a cell nucleos. They prokaryotes are divided into two domains: Bacteria and archaea. They differ from eukaryotes, which have a cell nucleous.
Protist: Diverse group of eukaryotic microorganisms
Microbial: a microorganism, pathogenic bacterium
Photosynthetic: a process that converts carbon dioxide intoorganic compounds, especially sugars, using the energy from sunlight.
Aerobic: is an organism that can survive and grow in an oxygenated environment
Organism: is any living system (such as animal, plant, fungus, or micro-organism)
Archaea: Any single-celled prokaryotes genetically distinct from bacteria, often living in extreme environmental conditions.
Nucleotide: molecules that,when joined together, make up the structural units of RNA and DNA.
Molecular: A small particle
Cellular: the basic structural unit of all organisms.
Peptidoglycan: A polymer found in the cell walls of prokaryotes
Polymer: compound of many small molecules.
Membrane: the thin, limiting covering of a cell or cell part.
Thylakoid: is a membrane-bound compartment inside chloroplasts andcyanobacteria.
Heterotroph: An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.
Bio film: a thin usually resistant layer of microorganisms (as bacteria)
Pathogenicity: the disease-producing capacity of a pathogen.
Metabolic: is the set of chemical reactions that occur in living organisms to maintain life.
Proteobacteria: Is amajor group (phylum) of bacteria.
Cyanobacteria: blue-green algae or blue-green bacteria that obtain energy through photosynthesis.
Plasma membrane: cell wall, cell membrane
Sac: a bag-like structure
Alveolate: The alveolates ("with cavities") are a major line of protists.
Slime molds: fungi-like organisms that use spores to reproduce.
Multicellularity: Having orconsisting of many cells: multicellular organisms.
Diatom: any of numerous microscopic, unicellular, marine or freshwater algae of the phylum Chrysophyta
Rod: rod-shaped microorganism

Eukaryotic: group of organisms that have a cell nucleos
endospore: a spore formed within a cell of a rod-shaped organism.
Dehydrate: to deprive (a chemical compound) of water or the elements ofwater.
Chemoheterotroph: organisms that obtain energy by the oxidation of electron donating molecules in their environments
chemautrophos: organism, such as bacteria, that obtain its energy through oxidation of inorganic chemical compounds.
photoautotrophs: any organism that derives its energy for food synthesis from light and is capable of using carbon dioxide as its principal source ofcarbon.
Anthrax: an infectious disease cause by a bacteria
exotoxin: a soluble toxin excreted by a microorganism.
endotoxin: is a structural component in the bacteria which is released mainly when bacteria are lysed.
tick: Ticks are blood-feeding parasites
decomposer: organism, usually a bacterium or fungus, that breaks down the cells of dead plants and animals into simpler substances.Endosymbiosis: symbiosis in which one symbiont lives within the body of the other.
Pseudopodia: a temporary protrusion of the protoplasm
Algae: eukaryotic organisms ranging from microscopic single-celled forms to multicellular forms
