The path of water from soil upto secondary xylem is

Options

A. Soil `to` Root hair cell wall `to` Cortex `to` Endodermis `to` Pericycle `to` Protoxylem `to` Metaxylem
B. Metaxylem `to` Protoxylem `to` Cortex `to` Soil `to` Roothair
C. Cortex `to` Root hair `to` Endodermis `to` Pericycle `to` Protoxylem `to` Metaxylem
D. Pericycle `to` Soil `to` Root hair `to` Cortex `to` Endodermis `to` Protoxylem `to` Metaxylem

Answer

A

Explanation

Water enters through the root hair cells and moves across the cortex of the root either via the cytoplasm of the cells in between the root hair cell and the xylem. When the water reaches a part of the root called the endodermis it encounters a thick waxy band of suberin in the cell walls.
