Plant roots are not green, why? Also what do the roots of a plant provide for the plant?

Because the roots are underground and they don't receive light, so there is no need for them to have chlorophyll. And that's why they are white and leaves are green. also, The roots anchor the plant in place, resisting the forces of wind and running water or mud flow.

can you explain it better

i heard they are taking it off i hope this isn't true but otherwise if it doesn't get taken off it will probably be in early december or early january of 2018-2019
