DENDROLOGY

Detailed explanation-1: -After traveling from the roots to stems through the xylem, water enters leaves via petiole (i.e., the leaf stalk) xylem that branches off from that in the stem.

Detailed explanation-2: -Plant stems have some very special cells called xylem. These cells form long thin tubes that run from the roots up the stems to the leaves. Their job is to carry water upward from the roots to every part of a plant.

Detailed explanation-3: -Xylem transports water in plants. Water is absorbed from the soil through root hair cells. Water moves by osmosis from root cell to root cell until it reaches the xylem. It is transported through the xylem vessels up the stem to the leaves.
