Geotropism
Geotropism, or gravitropism, is a directional growth response of plant organs to gravity. In most plants, roots show positive geotropism by growing toward the gravitational pull, while shoots display negative geotropism by growing away from gravity. This orientation supports effective nutrient and water uptake, stable anchorage, and proper shoot and root architecture.
Mechanism and sensing: Gravity detection occurs in specialized cells called statocytes, located in the root cap
History and genetics: Early experiments by Charles and Francis Darwin helped establish gravitropism as a distinct
Significance and applications: Geotropism is essential for seedling establishment and overall plant architecture. It interacts with
