binomial nomenclature

- Binomial nomenclature: The scientific naming system used for identifying and classifying species, where each species is given a two-part Latin name consisting of the genus and species names (e.g. Homo sapiens for humans).

- Taxonomy: The branch of science that deals with the classification of organisms, including naming, describing, and categorizing organisms based on their relationships and similarities.

- Pathogens: Microorganisms, such as bacteria, viruses, fungi, or parasites, that cause disease and illness in their host organism.

- Chemoautotrophic: Organisms that are able to produce their own energy through chemical processes, rather than relying on sunlight for energy like photosynthetic organisms.

- Heterosporous: A reproductive strategy found in some plants where two types of spores are produced - usually one type that develops into a male gametophyte and one that develops into a female gametophyte.

- Prion: A type of protein that can fold abnormally and cause transmissible spongiform encephalopathies, a group of neurodegenerative diseases in animals and humans.
