QuestionAnswer
asexual reproduction reproduction without the fusion of gametes
cell the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.
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 Blood circulation via the pumping of the heart pushing blood through closed vessels.
coelem the body cavity in metazoans, located between the intestinal canal and the body wall.
colonial of, relating to, or characteristic of a colony or colonies.
fluid a substance that has no fixed shape and yields easily to external pressure; a gas or (especially) a liquid.
feeding give food to.
endoskeleton a rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection.
excretion (in living organisms and cells) the process of eliminating or expelling waste matter.
exoskeleton a rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection.
filter a porous device for removing impurities or solid particles from a liquid or gas passed through it.
free-living living freely and independently, not as a parasite or attached to a substrate.
internal transport
invertebrates an animal lacking a backbone
levels of organization many different levels of biological organization. Some of these levels include: tissue, cell, organ, organ system, and organism. The smallest of this type of organization are the cells.
life functions A biological process is a process of a living organism. Biological processes are made up of any number of chemical reactions or other events that results in a transformation.
medusa a free-swimming sexual form of a coelenterate such as a jellyfish, typically having an umbrella-shaped body with stinging tentacles around the edge. In some species, medusae are a phase in the life cycle that alternates with a polypoid phase.
motility ability to move spontaneously and independently
multicellular having or consisting of many cells.
niche a shallow recess, especially one in a wall to display a statue or other ornament.
open circulatory system Open circulatory systems pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
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 A group of organs that work together to carry out a particular task.
parasite an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense.
polyp
reproduction the action or process of making a copy of something.
respiration the action of breathing.
response An action or movement due to the application of a stimulus.
sessile fixed in one place; immobile.
sexual reproduction the production of new living organisms by combining genetic information from two individuals of different types (sexes).
symmetry Correspondence of parts (in terms of form, size, distribution, or arrangement) on opposite sides of a dividing plane or on sides around an axis
tissue An aggregate of cells in an organism that have similar structure and function.
vertebral One of 23 bones (excluding the sacrum) in the cervical, thoracic and lumbar regions that comprise the spine. There are 7 cervical vertebrae, 12 thoracic and 5 lumbar vertebrae. The bottom of the spine is fused and forms the sacrum.
column The lower part of an awn in grasses, when distinctly different in form from the upper part, a structure (a gynostemium) in orchids which extends above the ovary of a flower and incorporates stigma, style and stamens.
