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; because of no exchange of genetic material. |
cell | Cells are the smallest unit of life that can replicate independently |
cephalization | a tendency in the development of animals to localization of important organs or parts in or near the head |
closed circulatory system | blood remains in blood vessels and heart at all time |
coelom | Body cavity in most multicellular animals; positioned inside the body to surround and contain the digestive tract and other organs |
colonial | living in colonies |
fluid feeding | organisms that feed on the fluid of other organisms |
endoskeleton | internal skeleton of the body of an animal |
excretion | The act or process of discharging waste matter from the blood, tissues, or organs. |
exoskeleton | Skeleton that is on the outside of an animals body (insects, Shells) |
filter feeding | a method of feeding occurring in some aquatic animals, such as planktonic invertebrates and whalebone whales, in which minute food particles are filtered from the surrounding water |
free-living | not dependent on presence or activities of other organisms for survival |
internal transport | circulatory System, digestive System, excretory system |
invertebrates | creatures without a backbone/spine. |
Levels of organization | cellular, tissues, organs? |
life functions | digestive System, circulatory System, respiratory System, excretory System, reproduction, nervous system |
medusa | one out of two Body forms of the cnidarians; typically motile with ring of tentacles surrounding an aboral mouth (jellyfish) |
motility | moving or capable of moving spontaneously |
motility/motile | moving or capable of moving spontaneously |
multicellular | composed of several or many cells. |
niche | relationship between organism and biotic and abiotic parts of Environment |
open circulatory system | blood is allowed to leave small arteries and soak through tissues ans sinuses until it goes back into the blood system |
organ | a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task. |
organ system | Group of organs that are working together |
parasite/parasitic | an organism that lives on or in an organism of another species, known as the host, from the body of which it obtains nutriment. |
Polyp | a sedentary type of animal form characterized by a more or less fixed base, columnar body, and free end with mouth and tentacles, especially as applied to coelenterates |
reproduction | the natural process among organisms by which new individuals are generated and the species perpetuated. |
respiration | inhalation and exhalation of air; breathing |
response | any behavior of a living organism that results from an external or internal stimulus |
sessile | permanently attached, not freely moving |
sexual reproduction | The production of a new living thing by two parent organisms, with each parent contributing half the material in the DNA of the offspring. The new living thing is genetically different from either parent. |
symmetry | the proper or due proportion of the parts of a body or whole to one another with regard to size and form |
tissue | an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism |
vertebral column | back bone or spine (The column of vertebrae between the skull and the hip bones, supporting the body and shielding the spinal cord.) |
