Chars of Life
Biology
| Term | Definition |
|---|---|
| Metabolism | the sum of all life processes carried out by an organism |
| Reproduction | process of making more of a species (not a metabolic process) |
| Nutrition | process of obtaining food |
| Digestion | process an organism uses to break down a large molecule into smaller molecules |
| Excretion | process an organism uses to release wastes |
| Transport | process of delivering materials to/from cells |
| Homeostasis (Dynamic Equilibrium) | process of keeping an internal balance (example...humans sweat to cool down their bodies) |
| Evolve | gradual changes in a population's gene pool over time (not a metabolic process) |
| Synthesis | process of putting small molecules together to form larger molecules |
| Regulation | process of controlling life processes |
| Locomotion | movement from place to place (NOT a characteristic of life) |
| Organelles | tiny structures inside a cell that each perform a specific job for the cell |
| Cell | the smallest structure found in all living things |
| Tissue | group of similar cells that perform a particular function |
| Organs | group of tissues that work together to perform closely related functions |
| System | a group of organs working together |
| Organism | an individual living thing |
| Unicellular | one celled, simple, lack tissues, organs, systems |
| Multicellular | many celled, complex, have tissues, organs, systems |
| Genetic Code (DNA) | linear polymer found on the nucleus of a cell and associated with the transmission of genetic information |
| Asexual reproduction | simple organisms, 1 parent, no gametes, identical offspring |
| Sexual Reproduction | complex organisms, 2 parents, gametes, variation in offspring |
| Circulation | movement of blood through the heart and blood vessels |
| Absorption | The process of absorbing or assimilating substances into cells or across the tissues and organs through diffusion |
| Photosynthesis | process plants use to make food |
| Cellular respiration | process all living things use to make energy inside cells |
| Differentiation (specialization) | process in which cells become specialized in structure and function |
| Autotroph (producer) | organism that can capture energy to produce its own food |
| Heterotroph (consumer) | organism that obtains energy from the food it consumnes |
| Inorganic molecules | molecules without carbon |
| Organic Molecules | A molecule that typically consists of carbon atoms. |
| Feedback Mechanism | a regulation system in a living body that works to return the body to its normal internal state, or commonly known as homeostasis. |
