Statocyte
Encyclopedia
Statocytes are cells thought to be involved in gravitropic
perception in plants, located in the cap tissue of the roots. They contain statoliths – starch-filled amyloplastic organelle
s – which sediment at the lowest part of the cells and initiate differential growth patterns, bending the root towards the vertical axis.
Gravitropism
Gravitropism is a turning or growth movement by a plant or fungus in response to gravity. Charles Darwin was one of the first to scientifically document that roots show positive gravitropism and stems show negative gravitropism. That is, roots grow in the direction of gravitational pull and stems...

Organelle
In cell biology, an organelle is a specialized subunit within a cell that has a specific function, and is usually separately enclosed within its own lipid bilayer....
