It was noticed that the leaves retained their normal appearance for several weeks, but that the tree eventually died. Arrange the following five events in an order that explains the mass flow of materials in the phloem. Water diffuses into the sieve elements. Leaf cells produce sugar by photosynthesis. Solutes are actively transported into sieve elements.
Sugar is transported from cell to cell in the leaf.
Sugar moves down the stem. Photosynthesis begins to decline when leaves wilt because a. flaccid cells are incapable of photosynthesis. CO2 accumulates in the leaves and inhibits photosynthesis. Root hairs are most important to a plant because they a. anchor a plant into the soil. It is located in the walls between endodermal cells and cortex cells.
