SLS Bio11 Animals (AT)
| Term | Definition |
|---|---|
| Asexual Reproduction | Biology (of reproduction) not involving the fusion of gametes. |
| Cell | The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic. |
| Cephalization | The concentration of sense organs, nervous control, etc., at the anterior end of the body, forming a head and brain, both during evolution and in the course of an embryo's development. |
| Closed Circuit Circulatory System | A system of internal transport in which the blood is confined to vessels |
| Coelom | The body cavity in metazoans, located between the intestinal canal and the body wall |
| Colonial | (of animals or plants) living in colonies |
| Fluid Feeding | The process where animals in this classification can gain their nutrients by eating the fluid from the prey that they catch or attack |
| Endoskeleton | An internal skeleton, such as the bony or cartilaginous skeleton of vertebrates |
| Excretion | The process of eliminating or expelling waste matter |
| Exoskeleton | A rigid external covering for the body in some invertebrate animals, esp. arthropods, providing both support and protection |
| Filter Feeding | Feeding by filtering out plankton or nutrients suspended in the water |
| Free-Living | Living freely and independently, not as a parasite or attached to a substrate |
| Internal Transport | The transport of various nutrients throughout the body |
| Invertebrates | Animals without a backbone |
| Level of Organization | The metaconcept for hierarchies that allows for non-fully-nested series of layers |
| Life Functions | Life functions are growth, respiration, reproduction, nutrition and excretion |
| Medusa | A free-swimming sexual form of a coelenterate such as a jellyfish, typically having an umbrella-shaped body with stinging tentacles around the edge. In some species, medusae are a phase in the life cycle that alternates with a polypoid phase |
| Motile | Capable of motion |
| Multicellular | Having or consisting of many cells |
| Niche | A position or role taken by a kind of organism within its community. Such a position may be occupied by different organisms in different localities, e.g., antelopes in Africa and kangaroos in Australia |
| Open Circulatory System | A circulatory that allows free movement throughout the body |
| Organ | A part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in humans |
| Organ System | A biological system is a group of organs that work together to perform a certain task |
| Parasite | An organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense |
| Polyp | A solitary or colonial sedentary form of a coelenterate such as a sea anemone, typically having a columnar body with the mouth uppermost surrounded by a ring of tentacles. |
| Reproduction | The action or process of making a copy of something |
| Respiration | A process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substance |
| Response | An excitation of a nerve impulse caused by a change or event; a physical reaction to a specific stimulus or situation |
| Sessile | Fixed in one place; immobile |
| Sexual Reproduction | The production of new living organisms by combining genetic information from two individuals of different types |
| Symmetry | The quality of being made up of exactly similar parts facing each other or around an axis |
| Tissue | Any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products |
| Vertebral Column | The spine; the backbone |
