Statocyte

Statocytes are cells thought to be involved in gravitropic perception in plants, located in the cap tissue of the roots.[1] They contain statoliths – starch-filled amyloplastic organelles – which sediment at the lowest part of the cells and initiate differential growth patterns, bending the root towards the vertical axis.[2]
