| Term | Definition |
|---|---|
| asexual reproduction | reproduction without sex of male and female gametes |
| cell | basic structure of all organisms |
| cephalization | concentration of nerve control and sense organs; forms a head and brain (evolution and embryo development) |
| closed circulatory system | have blood closed at all times within vessels; blood is pumped by a heart |
| coelom | body cavity, between intestinal canal and body wall |
| colonial | made up of many individual organisms to form a colony |
| fluid feeding | to feed on the fluid of other organisms (refers to: hematophagy or nectarivore) |
| endoskeleton | internal skeleton; bony, cartilage found in vertebrates |
| excretion | process of passing waste matter |
| exoskeleton | external skeleton; in invertebrates, esp. arthropods for support and protection |
| filter feeding | by aquatic animals; feeding by filtering out plankton/nutrients in the water |
| free-living | living freely; not as a parasite |
| internal transport | circulatory system is responsible for internal transport; blood, a pumping device (ex. heart), and blood vessels where the blood flows |
| invertebrates | animal lacking a backbone such as an arthropod |
| levels of organization | from simple to complex: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere |
| life functions | properties that distinguish living from dead or inanimate |
| medusa | a cnidarian where the body is shaped like an umbrella |
| motility/motile | ability to move spontaneously, consuming energy in the process |
| multicellular | having many cells |
| niche | role that an animal plays in an ecosystem |
| open circulatory system | where blood can mix in an organism |
| organ | a part of an organism that is self-contained and has a specific vital function |
| organ system | a group of organs that work together to perform one or more functions |
| parasite | organism that lives in or on another organism (its host) and benefits by deriving nutrients from the host |
| polyp | a phase in the life cycle that alternates with a medusoid phase |
| reproduction | process by which new individual organisms – "offspring" – are produced from their "parents" |
| respiration | conversion of oxygen into the energy; how they continue life |
| response | behaviour resulting from an internal or external force |
| sessile | permanently attached |
| sexual reproduction | reproduction; involves the union of gametes |
| symmetry | correspondence on opposite sides of an axis |
| tissue | ensemble of similar cells from the same origin that together carry out a specific function |
| vertebral column | series of vertebrae that provide support and form a case for the spinal cord |
