Question

Quizplus · Accepted Answer

The most recently formed layer of cells in large trees, known as the sapwood (located just under the bark), is responsible for transporting water throughout the tree. Heartwood, which is the older, central part of a tree, does not transport water. The statements about the formation of wood rings, the size of xylem vessels, and the proportion of vessels in wood produced in different seasons are incorrect.
