It’s made during a chemical reaction in the leaf

The flowers capture water and deliver it to the leaves

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: -Like all living things, plants need water. Water in the soil is absorbed by the roots and travels through the stems to the leaves. Water carries nutrients back and forth between roots and leaves. During photosynthesis, plant leaves need water, nutrients and sunlight to make their own food.
Detailed explanation-3: -Water Transport from Roots to Shoots The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement.
Detailed explanation-4: -Root pressure supplies most of the force pushing water at least a small way up the tree. Root pressure is created by water moving from its reservoir in the soil into the root tissue by osmosis (diffusion along a concentration gradient).
Detailed explanation-5: -Capillary action is the phenomenon that causes water to rise from plant roots to leaves. Moisture is transported through plants via transpiration, from roots to tiny pores on the underside of leaves, where it transforms into vapour and is discharged into the atmosphere.
