Photosynthesis

The leaves of plants convert carbon dioxide, water, and nutrient chemicals into plant food via a process called photosynthesis. Without this process, there would be little or no life on the planet. Most leaves have two parts: The lamina is the leaf’s blade; the petiole is its stalk. There are plants that have leaves that grow directly from the stem—these plants do not have a petiole. The petiole extends to the tip of the leaf and branches out to form its veins. Water and chemical nutrients flow through the veins of the leaf where they will be used in the making of the plant’s food. See Earth System Science, bio-capacity and bio-productivity
