to be eaten by animals
water , nutrients and oxygen
Plants roots that are above ground are called aerial roots. Examples are some types of orchids, mangroves, and banyon trees.
The zeros of functions are the solutions of the functions when finding where a parabola intercepts the x-axis, hence the other names: roots and x-intercepts.
