HORTICULTURE

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: -Water can get into xylem vessels by two routes-the symplast pathway and the apoplast pathway. If water travels via the symplast pathway then it travels from cell to cell through the cytoplasm. Neighbouring cells are connected by small channels in the cell walls called plasmodesmata.
