Biology Vocab Terms
| Term | Definition |
|---|---|
| Adaptation | Physiological process, structures, or the behaviors that help in survival and reproduction in a certain environment. |
| Atom | The smallest part of an element that retains the property of that element. |
| Autotroph | Organisms that make their own food (producers) |
| Binomial system | A way of naming species based on kingdoms |
| Biodiversity | The diversity of species and the interactions that sustain them. |
| Cell | The smallest unit of life. Every living thing must have at least one of these. |
| Cell Theory | The cell is the basic unit of life |
| Chromosomes | A structure inside the nucleus of a plant or animal cell. It is made of a protein and a single molecule of DNA. They carry information to help a cell grow and reproduce. |
| Community | A collection of populations interacting with each other. |
| Conclusion | The end of an experiment that includes the validity of the hypothesis based on the experimental evidence |
| Control | The variables that are not being tested and stay the same during the experiment. |
| Cytoplasm | A gel-like fluid inside the plasma membrane where other parts of the cell can operate. |
| Deductive Reasoning | The process of creating a hypothesis about how a certain observation or experiment will come about based on a supported generalization. |
| Deoxyribonucleic Acid (DNA) | A type of molecule that contains the hereditary information for life. |
| Domain | The most general ways organisms can be grouped; 3 major categories |
| Element | The substances that form all matter on Earth. |
| Energy | The ability to do work. |
| Eukaryotic | A type of cell that has an enclosed membrane and a nucleus. Generally larger than prokaryotic cells. Membrane enclosed nucleus |
| Evolution | The theory that modern organisms came from preexisting organisms |
| Experiment | A procedure to test and prove your hypothesis. |
| Gene | Units of heredity that provide the information necessary to control the cell. |
| Heterotroph | an organism that obtains nutrients by consuming other organisms |
| Homeostasis | Helps keep the cell functioning due to environmental change. It is maintained by mechanisms including respiratory, excretory, and circulatory systems. Ex. Body regulating temperature throughout day |
| Hypothesis | An educated guess based on prior knowledge on how the experiment will come about. |
| Inductive reasoning | The process of creating a generalization as a result of concluding observations that support it. |
| kingdom | Subdivisions of a domain that help classify specific organisms. They include Fungi, Plantae, and Animalia. |
| molecule | Combined atoms held together by chemical bonds. For example, H20 is a water molecule. |
| multicellular | An organism that has multiple cells in it. Most of the Fungi, Platea, and Animalia kingdoms are multicellular. |
| mutation | Mistakes within a DNA cell. Part of evolution. |
| Natural causality | The principle that all events can be traced to natural causes. Ex. A rainstorm causes a flood. |
| Natural selection | The process where organisms use specific traits to help cope with the conditions of the environment. |
| nucleus | Most important part of the cell. It controls it and holds all DNA information. Only in eukaryotic cells. |
| nutrient | The substances organisms need for energy/growth/to survive |
| observation | Using your sight, smell, taste, touch or hearing to help make a statement or remark. |
| organ | A collection of certain tissue that creates an important part of the human body. For example: skin, heart and kidney. |
| organelle | A subcellular structure in the cytoplasm that has specific tasks to perform within the cell. Ex: ribosomes and mitochondria |
| Organic molecule | Molecules that are primarily made of carbon atoms bonded with other elements and/or other carbon atoms. All living things on earth are composed of organic molecules. |
| organism | a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis. |
| Organ system | A group of organs that work together to perform tasks/functions like digestion. |
| photosynthesis | The process of how plants convert sunlight, carbon dioxide, and water into food in the form of glucose and release oxygen. |
| Plasma membrane | Membrane in the cell that separates the inside of the cell from the outside made of embedded proteins. |
| population | A particular group of species living and interacting with one another. |
| prediction | Something That you think will happen in the near future with supported data. |
| prokaryotic | A type of cell in bacteria and archaea that lacks a nucleus and membrane-bound organelles. Genetic material in cytoplasm. |
| question | A sentence worded to ask something they don’t know. (To ask Something unknown) |
| Scientific method | A method to make a scientific fact starting by making a hypothesis and experimenting to either accept, or reject the hypothesis, and re testing. Consists of multiple operations |
| Scientific theory | Explains a certain set of facts or idea about a specific situation or similar situation |
| species | A group of similar organisms and individuals who have the ability of reproducing and exchanging genes with one another. |
| tissue | A group of cells that have a similar structure and function of a unit. |
| unicellular | Consisting of one cell. |
| variable | An element, feature, or factor that is liable to change. |
