Humans have taken spiders into space more than once to study the importance of gravity to their web-building. What originally began as a somewhat unsuccessful PR experiment for high school students has yielded the surprising insight that light plays a larger role in arachnid orientation than previously thought

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.

If you tilt a plant, it will alter its growth to bend back upwards. But how does it detect the inclination? With cellular clinometers: cells filled with microscopic grains of starch called statoliths.
