Plants require some nutrients, such as carbon and nitrogen, in large quantities to survive. At the smallest scale are molecular interactions of photosynthesis and internal diffusion of water, minerals, and nutrients. Betalains are responsible for the deep red color of beets, and are used commercially as food-coloring agents. Francis Bacon published one of the first plant physiology experiments in 1627 in the book, Sylva Sylvarum. To function and survive, plants produce a wide array of chemical compounds not found in other organisms. For both of these organs to remain living, minerals that the roots acquire must be transported to the leaves, and the nutrients manufactured in the leaves must be transported to the roots. Photosynthesis requires a large array of pigments, enzymes, and other compounds to function. The chemical elements of which plants are constructed—principally carbon, oxygen, hydrogen, nitrogen, phosphorus, sulfur, etc.—are the same as for all other life forms: animals, fungi, bacteria and even viruses. Among the most important molecules for plant function are the pigments. Whatever name is applied, it deals with the ways in which plants respond to their environment and so overlaps with the field of ecology. A response to a directional stimulus, such as gravity or sunlight, is called a tropism. Rather, a short day plant requires a minimal length of uninterrupted darkness in each 24-hour period (a short daylength) before floral development can begin.
