asexual reproduction Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only
cell the smallest structural and functional unit of an organism
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 In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities.
coelom he body cavity in metazoans, located between the intestinal canal and the body wall.
colonial (of animals or plants) living in colonies.
fluid feeding Fluid feeders are organisms that feed on the fluid of other organisms
endoskeleton an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates.
excretion (in living organisms and cells) the process of eliminating or expelling waste matter
exoskeleton is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton
filter feeding feeding by filtering out plankton or nutrients suspended in the water.
free-living That lives independently of other organisms rather than part of a symbiotic or parasitic relationship.
internal transport A transport system is a means by which materials are moved from an exchange surface or exchange surfaces to cells
invertebrates an animal lacking a backbone
levels of organization The highest level of organization for living things is the biosphere; it encompasses all other levels.
life functions 1) All living things are organized and have chemicals. 2) Multicellular or unicellular. 3) Use energy. 4) Have a definite form and have a limited size. 5) Grow. 6) Respond to changes in environment. 7) Can reproduce. 8) Eventually die.
medusa is a form of cnidarian in which the body is shaped like an umbrella.
motility motility is the ability of organisms and fluid to move or get around.
multicellular having or consisting of many cells.
niche The niche that an organism occupies is the opening in the environment that the organism fills to make a living.
open circulatory system Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness
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.
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 answer or reply, as in words or in some action
sessile (of an organism, e.g., a barnacle) fixed in one place; immobile.
sexual reproduction the production of new living organisms by combining genetic information from two individuals of different types
symmetry is the balanced distribution of duplicate body parts or shapes within the body of an organism
tissue any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products
vertebral column another term for spinal column.
