TermDefinition
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

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
