2018-6-11 · Plants are quicker to react and more sensitive than you might think – they can detect light changes in a fraction of a second and can bend towards light sources within minutes – and they respond equally fast to gravity. For the first time last week, European scientists filmed roots growing in real-time on a plane that recreates different gravity levels.

Surface Gravity of the Planets and the Sun

The surface gravity, g, of an astronomical or other object is the gravitational acceleration experienced at its surface. The surface gravity may be thought of as the acceleration due to gravity experienced by a hypothetical test particle which is very close to the object''s surface and which, in order not to disturb the system, has negligible mass.

How does gravity affect plants and NON ...

Since plants are alive, gravity has a large effect on them. For instance, a tall tree needs to get water from the ground up to the leaves at the top of the tree and gravity makes this very hard. However, trees have many clever ways of transporting water 100s of feet up into the air despite gravity.
