| Organisms | have characteristics of living things |
| Life Functions | Processes or activities, common to all living things |
| Nutrition | The life processess in which the organism obtains (gets) and processes food |
| Autotrophs | Organisms that are able to make their own food |
| Heterotrophs | Organisms that are NOT able to make their own food |
| Ingestion | The way food is taken into an organism from its environment |
| Digestion | The process that changes food into a form that can be used by the cell |
| Transport | The life process that includes the absorption and circulation of materials throughout the organism |
| Absorption | The process by which the usable materials from food are taken into the cells and fluids of the body |
| Circulation | The movement of materials to and from the cells, within cells, and/or throught an organism |
| Excretion | The removal of waste materials produced in the cells as a result of life activities |
| Egestion | The process that removes undigested materials from the body |
| Regulation | The life process responsible for the control and coordination of all the various activities of an organism |
| Stimulus | A change in the internal or external environment |
| Synthesis | The process of producing complex substances from simpler substances |
| Growth | An increase in the size and/or number of cells of an organism |
| Locomotion | The process of moving from place to place |
| Motile | A condition of organisms that are able to move from place to place |
| Sessile | A condition of an organism that remains in one place their whole life |
| Reproduction | The production (making) of new organisms or cells |
| Metabolism | The sum total of all the life processes taking pace in an organism |
| Homeostasis | The maintenance of a stable internal (inside) environment in spite of changes in the external (outside) environment |
| Dynamic equilibrium | Another term for homeostasis |
| Feedback Mechanisms | Mechanisms for self-regulation |
| Biosphere | All living things and all the places they are found on Earth |
| Biodiversity | Biological diversity of life from bacteria to plants, animals, fungi, and protists |
| Species | Group of living things that can reproduce among themselves and have fertile offspring |
| Biology | The study of life |
| Organism | individual living thing |
| cell | basic unit of life |
| Metabolism | all of the chemical reactions with an organism |
| DNA and RNA | Genetic material or directions for an organism |
| Characteristics of life | Made of one or more cells, needs energy, responds to the environment, has reproduction and development |
| system | organized group of related parts that interact to form a whole, digestive system, nervous system |
| ecosystem | physical environment with different species that interact with other living and non-living things. |
| homeostasis | maintaing a constant internal environment in an organism: right oxygen level, temperature,or chemical balance. |
| Evolution | a change in living things over time |
| adaptation | inherited trait that gives individual organisms an advantage in survival and can be passed on to other generations. |
| Themes in Biology | Systems of related parts, structure and function, maintaining homeostasis, evolution, unity and diversity |
| Light microscope | enlarges objects 10-500X , light must be able to pass through the object |
| SEM or scanning electron microscope | Shows the surface of an dead object can magnify 1000X or more |
| TEM or transmission electron microscope | Shows the inside of an object. Magnifies 1000X or more |
| tissue | made up of specialized cells working together |
| organ | made up of specialized tissues working together |
| theory | an explanation of a natural occurrence that has been supported by many observations and experiments over time |
| law | explanation of relationships in nature under certain conditions |
| adaptation | changes in a species over time as a result of inherited characteristics |
