How do Plants sense Gravity? | Biomechanics in the Wild
Specific plant cells have gravitational sensors within, called statoliths. These sensors are made up of a heavy, liquid-like starch. Due to the force of gravity, these heavy sensors deposit at the bottom of the cell, like a sticky syrup.

Plant responses to gravity
Gravitropism is the ability of plants to perceive and respond to the gravity vector and orient themselves accordingly. The gravitropic pathway can be divided into three main components: perception, biochemical signaling, and differential growth.

How plants grow under gravity conditions besides 1
Gravity is one of the most stable and ubiquitous environmental parameters on the surface of the earth and it ranges from 9.764 to 9.834 m/s 2 (Hirt et al. 2013) in air or water.Gravitational force can be considered as the product of mass and standard gravity (g).As a plant grows and increases its biomass, gravitational force that is exerted on the plant body …

Plant responses to hypergravity: a comprehensive review
The plant responses to hypergravity can be a function of hypergravity intensity and the duration of exposure (Nunes et al. 2018).Moreover, since the plants or seeds perceive hypergravity as a mechanical force—through mechanosensors rather than gravity vector through statoliths (Soga et al. 2005a; Hattori et al. 2020)—it is reported that the mass of the cell/protoplast in totality could ...

Abstract. Tropisms are growth-mediated plant movements that help plants to respond to changes in environmental stimuli. The availability of water and light, as well as the presence of a constant gravity vector, are all environmental stimuli that plants sense and respond to via directed growth movements (tropisms).

Plant Tropisms. Plant roots always grow downward because specialized cells in root caps detect and respond to gravity. This is an example of a tropism. A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism. Plants also exhibit phototropism, or growing toward a
