- 1biologythe scientific study of life
- 2cellthe basic unit of structure and function in all living things
- 3unicellular organisman organism made up of a single cell; some examples include paramecia and bacteria
- 4multicellular organisman organism composed of more than one cell; these organisms usually have organized tissues, organs, and organ systems
- 5emergent propertiesfunctions or traits that appear as biological complexity increases
- 6biospherethe regions of the Earth's crust, waters, and atmosphere inhabited by living things
- 7ecosystema biological community together with the associated abiotic environment
- 8communityinteracting populations in a particular area
- 9populationorganisms of the same species in a particular area
- 10organisman individual living thing (ex. horse)
- 11organ systema system composed of several organs working together; found in complex organisms (ex. nervous system)
- 12organa group of tissues functioning together for a specific task (ex. brain)
- 13tissuea group of cells with a common structure and function (ex. nervous tissue)
- 14moleculeunion of two or more atoms
- 15atomsmallest unit of an element; composed of electrons, protons, and neutrons
- 16energythe capacity to do work
- 17metabolismall chemical reactions involved in maintaining the living state and organization of a cell or organism
- 18photosynthesisa process that uses energy from sunlight to reduce carbon dioxide to carbohydrate, transforming solar energy into chemical energy
- 19homeostasismaintenance of normal internal conditions (balance) in a cell or organism by means of self-regulating mechanisms
- 20reproductionthe process in which organisms produce other organisms like themselves
- 21genethe molecular unit of heredity; a region of DNA that encodes a functional RNA or protein product
- 22adaptationa modification that makes an organism better able to function in a particular environment
- 23evolutionthe process in which populations of organisms change over the course of many generations to become more suited to their environments
- 24taxonomythe discipline of identifying and grouping organisms according to certain rules; related to evolutionary relationships between life forms
- 25systematicsthe study of the evolutionary relationships between organisms
- 26domain Bacteriaa domain whose organisms are prokaryotic but differ from archaea because they have their own genetic, biochemical, and physiological characteristics
- 27domain Archaeaa domain that contains prokaryotic cells that often live in extreme habitats and have unique genetic, biochemical, and physiological characteristics that separate them from bacteria
- 28domain Eukaryaa domain consisting of organisms with eukaryotic cells; includes protists, fungi, plants, and animals
- 29prokaryotic cella cell that lacks a membrane-bound nucleus and organelles; the cell type within the domains Bacteria and Archaea
- 30eukaryotic cella type of cell that has a membrane-bound nucleus and membranous organelles; found in the domain Eukarya
- 31protiststhe group of eukaryotic organisms that are not a plant, fungus, or animal. They are generally a microscopic complex single cell, and they evolved before other eukaryotes
- 32planta multicellular photosynthetic organism
- 33funguseukaryotic saprotrophic decomposer; the body is made up of filaments called hyphae that form a mass called a mycelium
- 34animala multicellular; heterotrophic eukaryote that undergoes development to achieve its final form; characterized by the presence of muscular and nervous tissue
- 35binomial nomenclaturea system biologists use to assign each living thing a two-part scientific name; the first word signifies the genus and the second signifies the species
