 Symmetry (biology) - Wikipedia, the free encyclopedia The elaborate patterns on the wings of butterflies are one example of biological symmetry. This type of symmetry is especially suitable for sessile animals such as the sea anemone, floating animals such as jellyfish, and slow moving organisms such as sea stars (see special forms of radial symmetry). Animals in the phyla cnidaria and echinodermata exhibit radial symmetry. en.wikipedia.org /wiki/Radial_symmetry   (606 words)

Last check: 2007-11-01) Symmetry is a characteristic of geometrical shapes, equations and other objects; we say that such an object is symmetric with respect to a given operation if this operation, when applied to the object, does not appear to change it. Symmetry is used in the design of the overall floor plan of buildings as well as the design of individual building elements such as doors, windows, floors, frieze work, and ornamentation; many facades adhere to bilateral symmetry. Symmetry is also an important consideration in the formation of scales and chords, traditional or tonal music being made up of non-symmetrical groups of pitches, such as the diatonic scale or the major chord. www.onlineencyclopedia.org /s/sy/symmetry.html   (1201 words)

 Symmetry For a common notion of symmetry in Euclidean space, G is the Euclidean group E(n), the group of isometries, and V is the Euclidean space. A glide reflection symmetry (in 3D: a glide plane symmetry) means that a reflection in a line or plane combined with a translation along the line / in the plane, results in the same object. Symmetry does not by itself confer beauty to an object — many symmetrical designs are boring or overly challenging, and on the other hand preference for, or dislike of, exact symmetry is apparently dependent on cultural background. www.brainyencyclopedia.com /encyclopedia/s/sy/symmetry.html   (2856 words)

 Radial symmetry - the free encyclopedia   (Site not responding. Last check: 2007-11-01) In biology, radial symmetry is a property of some multicellular organisms. Any cut through the center of a radially symmetric organism, with the plane of the cut going from the top to the bottom (dorsal to ventral), results in roughly equal halves in terms of organs and body parts. Starfish possess a variant of radial symmetry in which orientations of 72 degree rotation are considered equivalent; this is known as www.free-web-encyclopedia.com /default.asp?t=Radial_symmetry   (100 words)

 AllRefer.com - symmetry, biological (Zoology: General) - Encyclopedia Radial, or line, symmetry, as exemplified by a cone or a disk that is symmetrical about a central axis, is especially suitable for sessile or floating animals. Radial symmetry is seen in sessile organisms such as the sea anemone, floating organisms such as jellyfish, and slow-moving organisms such as sea stars, or starfish. Many jellyfish have four radial canals and are said to have tetramerous radial symmetry; sea stars, with five arms, have pentamerous radial symmetry. reference.allrefer.com /encyclopedia/S/symmetryb.html   (463 words)

 Symmeter.com - Symmetry Measurement and Analysis Tools The term bi-lateral symmetry refers to side-to-side symmetry, as if a mirror line was placed on the image, typically (but not necessarily) in a top to bottom fashion. Radial symmetry is a measure of the image as if it were divided into a series of pie-shaped segments and each segment were compared to its opposite segment. In effect, when measuring radial symmetry, the image is divided into a number of segments, sort of like equally sized pie slices in a pie chart. www.symmeter.com /concept.htm   (464 words)

 radial symmetry   (Site not responding. Last check: 2007-11-01) In biology, radial symmetry is a characteristic that is used to help classify multicellular organisms. Organisms with bilateral symmetry, on the other hand, have two orientations: dorsal-ventral, as well as anterior-posterior. Jellyfish and ctenophores are the only animals with true radial symmetry; echinoderms have partial radial symmetry. www.wapipedia.com /wikipedia/mobiletopic.aspx?cur_title=radial_symmetry   (159 words)

 Body Symmetry Webster defines symmetry as "..correspondance in size, shape, and relative position of parts on opposite sides of a dividing line...about a center or axis." Symmetry implies a balance or equality of shape and proportion on opposite sides of a plane through an object. An object displaying radial symmetry is one where all planes passing through a central (usually vertical) axis have a mirror image on the other side. Radial symmetry — The vast majority of organisms displaying radial symmetry are anchored to the substrate (often referred to as a sessile lifestyle, sort of like couch potatoes). science.kennesaw.edu /biophys/biodiversity/animalia/symmetry.html   (743 words)

 LiveScience.com - Symmetry in Nature: Fundamental Fact or Human Bias? In biology, recent studies have found that humans and other animals are highly attuned to symmetry in each other and often use it to gauge beauty and health during mate selection. Symmetry is also prevalent in the physical sciences and is woven into the very laws that govern our universe. Symmetry is so integral to the way the universe works that Albert Einstein used it as a guiding principle when he devised his General Theory of Relativity. www.livescience.com /othernews/051221_symmetry_nature.html   (1394 words)

 Petal   (Site not responding. Last check: 2007-11-01) The petals are usually the most conspicuous parts of a flower, and the petal whorl or corolla may be either radially or bilaterally symmetrical. Many flowers are symetrical in only one plane (i.e., symmetry is bilateral) and are termed irregular or zygomorphic (meaning yoke- or pair-formed). In irregular flowers, other floral parts may be modified from the regular form, but the petals show the greatest deviation from radial symmetry. www.backyardagora.com /glossary/petal.htm   (315 words)
