SLS-Bio11 Animals JE


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; it does not involve the fusion of gametes and almost never changes the number of chromosomes.
Cell the smallest structural and functional unit of an organism
Cephalization a tendency in the development of animals to localization of important organs or parts in or near the head.
Closed circulatory system have the blood closed at all times within vessels of different size and wall thickness, blood is pumped through heart to vessels
Coelom the main body cavity of many animals. It is lined with an epithelium derived from mesoderm.
Colonial Possessing or inhabiting a colony or colonies.
Fluid feeding organisms that feed on the fluid of other organisms.
Endoskeleton an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates.
Excretion the process of eliminating or expelling waste
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.
Internal transport The transport of matter within the body
Invertebrates Having no backbone or spinal column
Levels of organization living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
Life functions The function of matter turning into an organism
Medusa is a form of cnidarian in which the body is shaped like an umbrella
Motility mental imagery that arises primarily from sensations of bodily movement and position rather than from visual or auditory sensations.
Motility/Motile Moving or having the power to move spontaneously. Of or relating to mental imagery that arises primarily from sensations of bodily movement and position rather than from visual or auditory sensations.
Multicellular An organism having or consisting of many cells
Niche The way in which an organism fits into an ecological community or ecosystem
Open circulatory system The open circulatory system is common to molluscs and arthropods, 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 one or more functions. Each does a particular job in the body, and is made up of certain tissues
Parasite/Parasitic An organism that lives and feeds on or in an organism of a different species and causes harm to its host
Polyp The hollow, columnar, sessile form of Cnidarians
Reproduction Is the biological process by which new individual organisms and are produced from their "parents".
Respiration the act of respiring; inhalation and exhalation of air; breathing
Response Any behavior of a living organism that results from an external or internal stimulus
Sessile To be fixed in one place (barnacles)
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 Is a cellular organizational level intermediate between cells and a complete organ
Vertebral column The series of vertebrae that extend from the cranium to the coccyx, and serves as a flexible bony case for the spinal cord
