How does water reach the cells of the xylem in the roots of plants?
How does water reach the cells of the xylem in the roots of plants?
By crossing the suberised matrix in the endodermis
By moving through the apoplast
By passing through the symplast
By penetrating the cortical cells
Solution
The water moves through the symplast and crosses a membrane to reach the cells of the xylem. The movement of water through the root layers is ultimately symplastic in the endodermis, which is the only way water and other solutes can reach the xylem.
