Plants react directy to gravity, it's called geotropism. Magnetism is likely to have little biological effect, e.g. plants still grow upward all over the world, although the earth's magnetic field depends on your location.

Yes . Magnetism is produced by motion of electrons. Water when in motion causes magnetism The sap flowing in the plant contains water. The push of gravity causes the sap to flow. If you put a compass needle near a root of a tree the needle would deflect.
Plants have the energy to grow upwards against gravity. They have a controls system designed to do that because they seek radiative energy from the Sun.

Technically, everything in the universe which has mass has gravity, and there are doubtless multiple electromagnetic molecular bonds in something as a complex as a plant, so... yes. But only to the extent that just about everything on Earth is related to gravity and magnetism.

Plants grow with their stems upward away from gravity, and toward sunlight, their roots downward due to gravity's pull, I suspect if you tried to grow a plant on a spinning turntable it would be quite an interesting outcome.
