Asexual reproduction A mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it is reproduction which almost never involves ploidy or reduction.
Cell The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
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 Has the blood closed at all times within vessels of different size and wall thickness. In this type of system, 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 Several individual organisms (especially of the same species) living together in close association.
Fluid feeding Getting your nutrients by consuming the fluids of another organism.
Endoskeleton The internal skeleton; bony and cartilaginous structure (especially of vertebrates).
Filter Feeding An aquatic animal that feeds on particles or small organisms strained out of water by circulating them through its system: includes most of the stationary feeders, as clams, oysters, barnacles, corals, sea squirts, and sponges.
Free-living Living independently of another organism; not part of a parasitic or symbiotic relationship.
Internal transport A transport system is a means by which materials are moved ('transported') from an exchange surface or exchange surfaces to cells* located throughout the organism.
Invertebrates The definition of an invertebrate is an animal without a backbone.
Levels of organization The biological levels of organization range from a single organelle all the way up to the biosphere in a highly structured hierarchy.
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 (as opposed to the polyp form).
Motility The ability of an animal to move food through its digestive tract; peristaltic movement.
Motility/Motile Of, pertaining to, or relating to motility; capable of moving or self-propelling.
Multicellular Multicellular organisms are organisms that consist of more than one cell, in contrast to single-celled organisms.
Niche The specific area where an organism inhabits.
Open Circulatory System Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities.
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 An organ system is a group of organs that work together to perform one or more functions. Organs make up an organism.
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 production of offspring by a sexual or asexual process.
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 substances.
Response An action or movement due to the application of stimulus.
Sessile (Of a plant or animal structure) attached directly by its base without a stalk or peduncle.
Sexual Reproduction The production of new living organisms by combining genetic information from two individuals of different types (sexes) A male and a female.
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.
