Water and solute molecules never have to enter a cell because they can travel from the epidermis to the root xylem by moving through the cell walls and spaces between cell walls

Question

Quizplus · Accepted Answer

Water and solute molecules can enter a cell, but they also have the option to move from the epidermis to the root xylem via the apoplast route, which involves movement through the cell walls and spaces between cells, without entering the cytoplasm. However, to reach the xylem, they must eventually pass through a selective barrier (the endodermis) via the symplast route, which involves entering the cells.
