- Determine the collective true-false status of the statements using the choices below. I. After soil water crosses a root’s epidermis, it seeps into parenchyma that forms the root’s region of cortex until it reaches the vascular cylinder.; II. In a typical eudicot root, the vascular cylinder divides ground tissue into regions of pith and cortex.; III. By contrast, the vascular cylinder in a typical monocot root contains very little pith or none at all.; IV. Water and substances dissolved in it must pass through the endodermis of a root’s vascular cylinder before entering the xylem for distribution to the rest of the plant. Only two (2) statements are true. None of the statements is true. Only one (1) statement is true. Only three (3) statements are true. All statements are true.arrow_forwardDetermine the collective true-false status of the statements using the choices below. I.
