Quizplus · Accepted Answer

Marcello Malpighi's experiment with removing the bark from a tree led to the discovery that the bark above the girdle swelled, which indicated that the flow of solutes in the phloem had stopped. This is because the phloem, which is located just beneath the bark, is responsible for transporting nutrients and sugars produced by photosynthesis down from the leaves to other parts of the plant. When the bark was removed, this flow was interrupted, causing the accumulation of solutes above the girdle and leading to swelling.
