Water is absorbed by plant roots and transported, by capillary action, through the fibrous material of the plant stem, to the leaves.
Food material prepared by the leaves is transported to the roots.
Sugar is transported through a plant by the "veins" in the plant called phloem. Xylem is the other transportation system that transports water.

Because sugar is transported through phloem and water is transported through xylem.

Water (H2O) is taken by the roots of plants and it comes out through the leaves during transpiration.
Photosynthesis occurs in the leaves of plants. The leaves allow CO2 to come in through the leaves. The sunlight turns the water that comes in from the roots through the stem into the leaves to make a chemical change in the H2O and CO2 into sugar.
If by "food" you mean the product of photosynthesis, this is transported through the plant (from the leaves and green parts) by the Phloem vessels - this is generally in a downward direction. If by "food" you mean nutrients that are absorbed from the soil, these are absorbed in solution by the roots and then transported in an upward direction throughout the plant by the Xylem vessels
Xylem transports water up to the leaves.Water:Is absorbed from the soil through root hair cellsIs transported through the xylem vessels up the stem to the leaves.Evaporates from the leaves (transpiration)But the phloem transports nutrients to the leaves.

The leaves have small openings to bring in CO2. They absorb sunlight and use this with the water that comes into the roots and up through the stems. The plant sugars are then transported through the sap to other parts of the plant.
