Water is absorbed by root hairs, which are extensions of epidermal cells. From the epidermis, water moves inward through the cortex. It then crosses the endodermis (where the Casparian strip regulates passage), enters the pericycle, and finally moves into the xylem for upward transport. The correct pathway is Epidermis → Cortex → Endodermis → Pericycle.

Water enters the root through the epidermis, moves through the cortex, endodermis, pericycle, and finally into the xylem.

Water can move through the cortex via two main pathways: the apoplast pathway (through cell walls and intercellular spaces) and the symplast pathway (through the cytoplasm connected by plasmodesmata). The Casparian strip in the endodermis forces water to enter the symplast, providing a selective barrier.
