Let’s assume the plant was sent into space in a comfy space shuttle with sufficient nutrients, gases, water, artificial light etc. but there is no gravity for the plant to grow against. Would geotropism still exist?
Edit: In the absence of gravity, which direction would the plant grow in? Eg. would it sprawl along the surface it is rooted to?
In: Biology
As long as there’s a gravity field, geotropism would exist, just maybe not in the amount it does here on Earth surface. If you’re in earth orbit, you still have gravity, but because the room (spaceship) is also moving in orbit, you fall at the same rate that gravity pulls on you.
If you were in deep space between galaxies, then you would indeed have a minimal net gravity direction.
