stat·o·lith

 (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)
n
1. (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 fibres
2. (Botany) any of various movable inclusions, such as starch grains, that occur in plant cells and are thought to function in geotropic responses
ˌstatoˈlithic adj

stat•o•lith

(ˈstæt l ɪθ)

n.
any of the granules of lime, sand, etc., contained within a statocyst.
