Vitis vinifera being a plant uses photosynthesis as the main way to obtain energy. Photosynthesis is the process of taking sunlight as an energy source. The sunlight is them converted into chemical energy which then creates organic compounds which were made from inorganic compounds captured outside of the plant.
One big component of photosynthesis is water. Water is captured by the roots of the grapevine. Water always moves up the plant, also the movement is always from high to low pressure and low solute to high solute. The water is transported throughout the plant but a structured called xylem. Another structure in the vine called the phloem is responsible for transporting nutrients throughout the plant.
Pholem and xylem make up the cambium which you can see in the picture above.
