What characteristic is associated with the crown of a tree?

The crown of a tree refers to the upper part of the tree, which includes the branches and leaves. This area is specifically associated with photosynthesis, the process by which plants convert sunlight into chemical energy. The leaves contain chlorophyll, which captures light energy needed for this process, allowing the tree to produce food from carbon dioxide and water. Thus, the crown plays a vital role in the tree’s growth and energy production, making it critical for the overall health of the tree.

While the other options pertain to various functions of a tree, they do not directly correspond to the primary characteristic of the crown. The root system supports the tree and anchors it to the ground, storage of nutrients typically occurs within the trunk and roots, and absorption of water occurs primarily through the roots, which transport water to the crown for photosynthesis.
