1.	Question : What essential role does the root endodermis play during mineral absorption in plants?
Answer» Solution :lons are absorbed from the soil by both passive and active TRANSPORT. Specific proteins in the membranes of root hair cells actively pump ions from the soil into the cytoplasms of the EPIDERMAL cells. The endodermal cells have many transport proteins embedded in their plasma membrane, they let some solutes cross the membrane, but not others. Infact, transport proteins of endodermal cells are control points, where a plant adjusts the quantity and types of solutes that REACH the XYLEM.
