In one to 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 plant’s ability to survive.

The purpose of the roots in a plant is to anchor it in the soil, absorb water and nutrients, and provide structural support. A disease that harms the roots of a flowering plant would severely impact its ability to absorb water and nutrients, leading to stunted growth, wilting, and ultimately, the plant's inability to survive.
