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. It provides energy for the active transport of minerals into the vascular bundle from the cortex. It ensures that all minerals are absorbed from the soil in equal amounts. It ensures that all water and dissolved substances must pass through a cell before entering the vascular bundle. It provides increased surface area for the absorption of mineral nutrients.
