In one or two sentences, identify the purpose of the roots in a plant and how a disease that harms the roots of a flowering plant would affect the plants ability to survive

The purpose of the roots in a plant is to absorb water and nutrients from the soil and anchor the plant in the ground. If the roots of a flowering plant are harmed by a disease, the plant's ability to survive will be greatly reduced as it will not be able to absorb the necessary water and nutrients from the soil.
