TermDefinition
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.
Cephilization 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 closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities.
Coelom the body cavity in metazoans, located between the intestinal canal and the body wall.
Colonial Organisms living in groups forming colonies
Fluid Feeding animals in this classification can gain their nutrients by eating the fluid from the prey that they catch or attack.
Endoskeleton an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates.
Excretion 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 Feeding feeding by filtering out plankton or nutrients suspended in the water.
Free living living freely and independently, not as a parasite or attached to a substrate.
Internal transport When an animal has proteins transported throughout its system
Invertebrates an animal lacking a backbone, such as an arthropod, mollusk, annelid,and coelenterate.
Levels of Organization a group of organs that work together to perform a specific function in a living thing
Life functions 1)All living things are highly organized and contain many complex chemical substances.2) All living things contain cells.3) All living things use energy.4) Living things have a definite form.5) Living things grow..7)Living things can reproduce.8)they die.
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
Motile capable of motion.
Multicellular having or consisting of many cells.
Niche a position or role taken by a kind of organism within its community. Such a position may be occupied by different organisms in different localities
Open circulatory system Open circulatory systems (evolved in crustaceans, insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells.
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 perform a certain task.
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 organised bodies.
Respiration a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide
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
Symmetry balanced distribution of duplicate body parts or shapes.
Tissue any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.
Vertebral column The series of vertebrae extending from the base of the skull to the tip of the tail that forms the supporting axis of the body in vertebrate animals. It encloses and protects the spinal cord
