SLS Bio11 Animals PJ

asexual reproduction A form of reproduction that does not involve meiosis, ploidy reduction or fertilization, and the offspring is a clone of the parent organism; because of no exchange of genetic material.
cell Cells are the smallest unit of life that can replicate independently
cephalization a tendency in the development of animals to localization of important organs or parts in or near the head
closed circulatory system blood remains in blood vessels and heart at all time
coelom Body cavity in most multicellular animals; positioned inside the body to surround and contain the digestive tract and other organs
colonial living in colonies
fluid feeding organisms that feed on the fluid of other organisms
endoskeleton internal skeleton of the body of an animal
excretion The act or process of discharging waste matter from the blood, tissues, or organs.
exoskeleton Skeleton that is on the outside of an animals body (insects, Shells)
filter feeding a method of feeding occurring in some aquatic animals, such as planktonic invertebrates and whalebone whales, in which minute food particles are filtered from the surrounding water
free-living not dependent on presence or activities of other organisms for survival
internal transport circulatory System, digestive System, excretory system
invertebrates creatures without a backbone/spine.
Levels of organization cellular, tissues, organs?
life functions digestive System, circulatory System, respiratory System, excretory System, reproduction, nervous system
medusa one out of two Body forms of the cnidarians; typically motile with ring of tentacles surrounding an aboral mouth (jellyfish)
motility moving or capable of moving spontaneously
motility/motile moving or capable of moving spontaneously
multicellular composed of several or many cells.
niche relationship between organism and biotic and abiotic parts of Environment
open circulatory system blood is allowed to leave small arteries and soak through tissues ans sinuses until it goes back into the blood system
organ a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task.
organ system Group of organs that are working together
parasite/parasitic an organism that lives on or in an organism of another species, known as the host, from the body of which it obtains nutriment.
Polyp a sedentary type of animal form characterized by a more or less fixed base, columnar body, and free end with mouth and tentacles, especially as applied to coelenterates
reproduction the natural process among organisms by which new individuals are generated and the species perpetuated.
respiration inhalation and exhalation of air; breathing
response any behavior of a living organism that results from an external or internal stimulus
sessile permanently attached, not freely moving
sexual reproduction The production of a new living thing by two parent organisms, with each parent contributing half the material in the DNA of the offspring. The new living thing is genetically different from either parent.
symmetry the proper or due proportion of the parts of a body or whole to one another with regard to size and form
tissue an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism
vertebral column back bone or spine (The column of vertebrae between the skull and the hip bones, supporting the body and shielding the spinal cord.)
