What function do roots perform in trees?

Roots play a vital role in the overall health and stability of trees, primarily through anchoring the tree in place and absorbing essential nutrients and water from the soil. The extensive root system helps prevent the tree from being uprooted by wind or heavy rain, providing stability. Additionally, roots facilitate the uptake of minerals and nutrients, which are crucial for the tree's growth and development. Water absorption is equally important, as it supports various physiological processes within the tree, including photosynthesis that occurs in the leaves.

While photosynthesis predominantly takes place in the leaves, the process relies on the nutrients and water absorbed by the roots. Gas exchange is primarily managed through leaves and stems, where stomata allow for the intake of carbon dioxide and release of oxygen. Flowering is related to the reproductive cycle of the tree and does not directly involve the root system’s functions. Thus, the multifaceted role of roots specifically in anchoring the tree and facilitating nutrient absorption makes this the correct choice.
