Hyacinth, as a plant, is a primary producer, meaning that it creates its own food. The process by which plants create their own food is called photosynthesis (as briefly discussed on the classification page). Using carbon dioxide, or CO2, found in the air, H2O, taken up by the roots, and sunlight, absorbed by the leaves, the plant produces both dextrose and oxygen.

CO2 + H2O à C6H12O6 + O2

The chemical formula for photosynthesis: one mole (a given quantity) of carbon dioxide (CO2) combined with one mole of water (H2O) produces, when exposed to sunlight, one mole of dextrose (C6H12O6) and one mole of oxygen (O2).

   Hyacinth, as plants, also possess tissues specific to nutrient absorption. The xylem and phloem are complex tissues composed of more than one cell type. They are found to be present in the vascular bundles. The primary purpose of xylem is to move water and dissolved minerals up the plant to provide nutrients and water to the leaves for photosynthesis. Phloem, on the contrary, serve to transport sugars and other food from the leaves (following photosynthesis) to the
rest of the plant.
