Explanation: 

Detailed explanation-1: -If the roots are white or tan colored, succulent when you pull on them and have fleshy white tips, then your root system is healthy.

Detailed explanation-2: -Generally, the whiter the roots, the healthier the plant will be. As plants grow older the roots can turn darker in color but the same principle applies. Roots that appear brown, black, soft or rotted indicate an unhealthy plant. A rotting, foul odor may also be present.

Detailed explanation-3: -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.

Detailed explanation-4: -The root system of a healthy plant should be firm and white. But when soil is soggy, fungal spores multiply and the fungus starts to spread3, developing in the extremities of the roots first. As the fungus advances, healthy portions of root turn brown and mushy as the roots die.

Detailed explanation-5: -Answer: Generally, the colour of the roots is white or brown. Question 2: Did you see any hair on the roots?
