Description

A beautiful lone leaf hanging on to life during Autumn. I love the bold yellow color against the background that I added to this piece. The texture really brings out the leaf and makes it pop. I also used digital painting effects and added a short inspirational quote. A green leaf is green because of the presence of a pigment known as chlorophyll, which is inside an organelle called a chloroplast. When they are abundant in the leaf's cells, as they are during the growing season, the chlorophyll's green color dominates and masks out the colors of any other pigments that may be present in the leaf. Thus the leaves of summer are characteristically green. Chlorophyll has a vital function: it captures solar rays and uses the resulting energy in the manufacture of the plant's food � simple sugars which are produced from water and carbon dioxide. These sugars are the basis of the plant's nourishment � the sole source of the carbohydrates needed for growth and development. In their food-manufacturing process, the chlorophylls breaks down and thus are being continually "used up". During the growing season, however, the plant replenishes the chlorophyll so that the supply remains high and the leaves stay green. In late summer, as daylight hours shorten and temperatures cool, the veins that carry fluids into and out of the leaf are gradually closed off as a layer of special cork cells forms at the base of each leaf. As this cork layer develops, water and mineral intake into the leaf is reduced, slowly at first, and then more rapidly. It is during this time that the chlorophyll begins to decrease.

Often the veins will still be green after the tissues between them have almost completely changed color.
