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 |
