• Prokaryote- cell without a nucleus • Bacillus- rod shaped • Coccus – circular shaped • Spirillum – spiral shape • Chemoheterotroph – consuming of chemical compounds • Photoautotroph- make energy from light • Chemoautotroph- make their own energy from chemical compounds • Binary fission- reproduction where bacterial divides in half • Conjugation- reproduction exchange genetic information • Endospore – reproduction when growth conditions are unfavorable • Virus- organism that contains DNA/RNA and a capsid • Capsid – out protein coating • Bacteriophage – viruses that infect bacteria (space capsule) • Lytic infection- quick reproduction cycle for viruses, where the host cell is lysed (shredded) • Lysogenic infection- reproduction cycle for viruses where virus integrates in DNA into the host cells DNA • Retrovirus- type of virus that works backwards making DNA from its RNA • Pathogen- disease causing agent • Vaccine- weakened strain of a virus • Disease- a change that disrupts the normal functions of the body • Germ theory- idea that infectious disease are caused by microorganisms • Vector- animals that carry a pathogen from one person to the next • Antibiotic- compounds that kill bacteria without harming other healthy cells • Immunity- your body’s ability to be able to remember how it fought off an infection • Inflammation- collection of white blood cells at the site of infection, may look swollen or be painful • Fever- raising the temp of the body to fight of an infection • Interferon- interfers with growth of a virus • Antigen- proteins on the surface of cells, usually a marker on a pathogen, tells the body that it is not supposed to be there • Humoral immunity- immune response involving antigens, antibodys, and B cells • Cell-mediated immunity- immune response in which the body attacks cells that have been infected, involves T cells (killer, suppressor, helper, and memory) • Antibody- proteins produced by our body that recognize and bind to antigens (Y shaped letter)
