Detailed explanation-1: -Water and mineral salts first enter through the cell wall and cell membrane of the root hair cell by osmosis.

Detailed explanation-2: -Water and minerals enter the root by separate paths which eventually converge in the stele, or central vascular bundle in roots. Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem.

Detailed explanation-3: -Water moves down its concentration gradient into root hair cells then travels through the root cortex and the endodermis before reaching the xylem. Water can get into xylem vessels by two routes-the symplast pathway and the apoplast pathway.
