| Term | Definition |
|---|---|
| asexual reproduction | a form of reproduction that does not involve meiosis, ploidy reduction or fertilization, and the offspring is a clone of the parent organism |
| cell | the structural, functional and biological unit of all organisms |
| cephalization | an evolutionary trend, whereby nervous tissue, over many generations, becomes concentrated toward one end of an organism. This process eventually produces a head region with sensory organs |
| closed circulatory system | A system where blood is closed at all times within vessels of different size and wall thickness. Blood is pumped by a heart through vessels, and does not normally fill body cavities. |
| coelom | the body cavity in metazoans, located between the intestinal canal and the body wall |
| colonial | having become established in a community in a new environment |
| fluid | having particles which easily move and change their relative position without a separation of the mass, and which easily yield to pressure |
| feeding | giving food or nourishment |
| endoskeleton | the internal skeleton; bony and cartilaginous structure (especially of vertebrates) |
| excretion | the process, act or function of discharging or ejecting waste product of metabolism, especially from the system of an organism |
| 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 | a circulatory system made of a pump and blood |
| invertebrates | an animal lacking a backbone, such as an arthropod, mollusk, annelid, coelenterate, etc. |
| levels of organization | arranged from the simplest to most complex: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere |
| life functions | nutrition, transport, respiration, excretion, elimination, reproduction, growth, repair, synthesis, locomotion, regulation |
| medusa | the freely-swimming, umbrella- or disk-shaped gelatinous form of cnidarians |
| motility | capable of moving or self-propelling |
| multicellular | having or consisting of many cells or more than one cell to perform all vital functions |
| niche | the role or function of an organism or species in an ecosystem |
| open circulatory system | circulatory system in which the heart pumps blood into vessels that have open ends |
| organ | a group of tissues that perform a specific function or group of functions |
| organ system | a group of organs that work together to carry out a particular task |
| parasite/parasitic | an organism that obtains nourishment and shelter on another orgnism |
| polyp | the hollow, columnar, sessile form of Cnidarians |
| reproduction | the production of offspring by organized bodies |
| respiration | any of the various analogous processes by which there is an exchange of gases |
| response | an action or movement due to the application of a stimulus |
| sessile | relating to the state of sessility or the inability to move actively or spontaneously |
| sexual reproduction | a mode of reproduction involving the fusion of female gamete and male gamete, which forms a zygote that potentially develops into genetically distinct offspring |
| 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 |
| vertebral | an animal with a back bone, to protect the spinal cord and provides a stable attachment for the muscles of the trunk |
| column | the lower part of an awn in grasses, when distinctly different in form from the upper part, a structure in orchids which extends above the ovary of a flower and incorporates stigma, style and stamens |
