A root statocyte in a vertical position: (1) Cell Wall (2) Endoplasmic Reticulum (3) Plasmodesma (4) Nucleus (5) Mitochondrion (6) Cytoplasm (7) Statolith (8) Root (9) Root cap (10) 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]
