Want this question answered?
nothing would happen...
what would happen to a car if its reaction force was less than the weight
we would fly up
The support force on an object is called the normal force because it is a force "normal" to the object. "Normal" in this sense means perpendicular.
The force that opposes a downward force on an object would be called the "normal force". For example, it is as a result of the normal force that people do not fall though the ground the same way that they fall through the air.
It depends on the magnitude of the forces.
every thing would weigh half its normal weight

Nothing would happen to the plant. It will have a normal growth provided other parameters are normal.

The deformation would increase because the force increases.
he would be normal again.

the force of the particals would prevent you from doing it.
A normal force is perpendicular to the surface. In physics class this is initially a horizontal surface in most problems. If so, the normal force would balance out the force caused by gravity (F=mg). If on an incline you would include a trigonometric function (F = mg sin(x) or mg cos(x)) depending on the location of the angle x.
