BIO 11 Animals B.L
SLS BIO 11 ANIMALS B.L
| Term | Definition |
|---|---|
| Asexual Reproduction | reproduction without 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 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 | a native or inhabitant of a colony. |
| Fluid Feeding | The process by which an animal feeds on fluid. |
| Endoskeloton | an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates. |
| Excretion | (in living organisms and cells) the process of eliminating or expelling waste matter. |
| Exoskeloton | a rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection. |
| Filter Feeding | (of an aquatic animal) 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 movement of a chemical substance through a gradient of concentration or electrical potential in the direction opposite to normal diffusion, requiring the expenditure of energy |
| Invertabrates | an animal lacking a backbone, such as an arthropod, mollusk, annelid, coelenterate, etc. The invertebrates constitute an artificial division of the animal kingdom, comprising 95 percent of animal species and about 30 different phyla. |
| Levels of Organization | Atoms are the smallest part of the cell that is studied in biology. |
| Life Functions | (Life function) A biological process is a process of a living organism. Biological processes are made up of any number of chemical reactions or other events that results in a transformation. |
| 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. |
| Motility/Motile | moving or capable of moving spontaneously |
| Multicellular | (of an organism or part) 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 | An open circulatory system is a system in which blood is not confined to vessels. After leaving the heart through major vessels, the blood then enters the hemocoel, the complex of blood-filled spaces adjacent to the organs. |
| 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 | is a group of organs that work together to perform a certain task. Common systems, such as those present in mammals and other animals, seen in human anatomy, are those such as the circulatory system, the respiratory system, the nervous system, |
| Parasite/Parasitic | an organism that lives in or on another organism and does the host some harm. |
| 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 | the action of breathing. |
| Response | an excitation of a nerve impulse caused by a change or event; a physical reaction to a specific stimulus or situation. |
| Sessile | (of an organism, e.g., a barnacle) fixed in one place; immobile. |
| Sexual Reproduction | he production of new living organisms by combining genetic information from two individuals of different types (sexes). |
| Symmetry | Correspondence of parts (in terms of form, size, distribution, or arrangement) on opposite sides of a dividing plane or on sides around an axis |
| Tissue | An aggregate of cells in an organism that have similar structure and function. |
| Vertabral Column | The series of vertebrae that extend from the cranium to the coccyx, providing support and forming a flexible bony case for the spinal cord. |
