Reiew basic biological principles
| Term | Definition |
|---|---|
| Characteristics of Life | OHGRADES |
| First level of organization | Cell |
| Homeostasis | Maintaining a stable/constant internal environment |
| Growth | The addition of body mass |
| Reproduction | The process of producing offspring |
| Adaptation | A characteristic that helps a living organism survive and reproduce in a given environmnet |
| Development | The changes an organism goes through in its lifetime |
| Respiration | The process of acquiring energy from food |
| Stimuli | A change in the environment that causes a response |
| Second level of organization | Tissue |
| Third level of organization | Organ |
| Fourth level of organization | Organ system |
| Biology | The science of life |
| Organization | Leveling by characteristic and complexity |
| Organelle | Structure within cells that carries out a particular function or job |
| Cell | Basic unit of structure and function of living things |
| Tissue | Group of cells of the same kind carrying out a particular function or job |
| Organ | Structure composed of one or more types of tissues |
| Organ system | Group of organs that work together to do a certain function |
| Organism | Individual living thing that may be made up of one or more cells |
| Evolution | A change in the characteristics of living organisms over time |
| Response | Reaction to a stimuli |
| Energy | The ability to do work |
| Autotroph | Store chemical energy in food molecules they produce |
| Food | Organic molecules that provide energy to do work and carbon to build cells |
| Producers | Autotrophs |
| Heterotrophs | Organisms that cannot make their own food so they must eat or absorb food |
| Consumers | Heterotrophs |
| Taxonomy | The science of classifying organisms |
| Taxonomic hierarchy | KPCOFGS |
| Archaebacteria | Ancient bacteria; prokaryote |
| Eubacteria | True bacteria; prokaryote |
| Protist | Eukaryote; amoeba and paramecium |
| Fungi | Eukaryote; mushrooms and puffballs |
| Plant | Eukaryote; oak tree and tulip |
| Animal | Eukaryote; dogs, whales and worms |
| Linnaeus | Father of taxonomy |
| Domain | Category in a level above the kingdom level; Archae, bacteria, eukarya |
| Prokaryotic | Cells that lack membrane bound organelles |
| Eukarotic | Cells that have membrane bound organelles |
| Nucleus | Control center of the cell |
| Scientific name | Genus species |
| Hooke | Scientist that named cells when he looked at cork under a microscope |
| Schleiden and Schwann | Proposed that cells are the basic building blocks of all living things |
| Virchow | Proposed that all cells come from pre-existing cells |
| Four parts found in all cells | Cytoplasm, ribosome, DNA and plasma/cell membrane |
| Ribosomes | Structures that produce proteins in all cells |
| Plasma membrane | Phospholipid layer that surrounds all cells |
| Cytoplasm | Gel-like liquid that suspends organelles and is found in all cells |
| DNA | Nucleic acid found in all cells |
| Unicellular organism | Organism made up of only one cell |
| Colonial organism | An organized structure composed of many individual one celled organisms that live and work cooperatively |
| Multicellular organism | Organism made up of many cells |
