Various dense cell organelles (amyloplasts, nuclei, mitochondria), which are movable when the plant is reoriented, have been thought of as possible candidates as statoliths.

WebWhen an animal moves, a statolith remains stationary for a brief instant because of inertial resistance, so it pushes more against the fibers located on the side opposite to the direction of motion (red lines). In the same way statoliths acting under the force of gravity allows cells to recognize up and down displacement. WebOct 1, 2009 · Gravity sensing occurs primarily in the statocytes, which are the columella cells of the root and lie in the endodermal layer of the shoot. The statocytes are characterized by the presence of large, starch-filled amyloplasts. These plastids are denser than the surrounding cytoplasm, and tend to sediment to the bottom of statocytes.

WebSep 11, 2024 · Statoliths are membrane-bound starch grains (amyloplasts) in gravity-detecting cells that can be found in the shoot cortex and the root columella [ 19 ]. The basis of the theory is that statoliths sink to the bottom of reoriented gravity-sensing cells due to the change in the gravity vector ( Figure 1 ).
