Question: 1 / 400

What are pan roots primarily responsible for?

Anchoring the tree at its base

Extending nutrients into the soil

Gravitational support extending 3-5 times the diameter from the tree

Pan roots, also known as lateral or structural roots, play a crucial role in providing stability and support to a tree. They tend to spread out horizontally and can extend significantly beyond the tree's diameter. The correct answer states that pan roots are primarily responsible for gravitational support extending 3-5 times the diameter from the tree, which emphasizes their importance in anchoring the tree in place, especially in the upper layers of soil.

This extensive lateral growth allows trees to maintain balance and resist various environmental forces, like wind. A well-developed system of pan roots can help prevent uprooting and ensure the tree remains stabilized over time, which is particularly vital for tall trees or those in windy conditions. Understanding the function of pan roots contributes to overall knowledge about tree health and risk assessment regarding potential hazards posed by trees in the landscape.
