stat·o·lith S0720800 (stăt′l-ĭth′)n.1. One of the small movable calcareous particles in a statocyst.2. One of the starch grains or other solid particles in a plant cell thought to function in the plant's response to gravity.statolith (ˈstætəʊˌlɪθ) n1. (Zoology) Also called: otolith any of the granules of calcium carbonate occurring in a statocyst: movement of statoliths, caused by a change in position of the animal, stimulates hair cells, which convey the information to the brain by nerve fibres2. (Botany) any of various movable inclusions, such as starch grains, that occur in plant cells and are thought to function in geotropic responses ˌstatoˈlithic adjstat•o•lith (ˈstæt l ɪθ)
n. any of the granules of lime, sand, etc., contained within a statocyst. [1895–1900] StatolithenUK
statolith[′stad·ə‚lith] (botany) A sand grain or other solid inclusion which moves readily in the fluid contents of a statocyst, comes to rest on the lower surface of the cell, and is believed to function in gravity perception. (invertebrate zoology) A secreted calcareous body, a sand grain, or other solid inclusion contained in a statocyst. Statolith (1) A synonym for otolith. (2) In plants, a small mobile starch grain found in cells of the rootcap, tips of cereal coleoptiles, and other growing parts. When the direction of the axis of the organ changes, the statoliths drop and exert pressure on the cytoplasm, resulting in geotropic bending of the organ. Statoliths are consumed by the plant during severe starvation, for example, when there is prolonged darkness. The cells that contain statoliths are called statocysts. statolithenUK
statolith [stat´o-lith] 1. a granule of the statoconia.2. a solid or semisolid body occurring in the labyrinth of animals.statolith (stăt′l-ĭth′)n. One of the small movable calcareous particles in a statocyst.statolith - (in plants) a solid inclusion within a cell, such as a starch granule, by means of which the position of the plant in relation to gravity is thought to be perceived.
- (in animals) a granule that stimulates sensory cells in a STATOCYST as the animal moves. see OTOLITH.
