Photomorphogenesis
Photomorphogenesis is a term from botany and describes the overall development of a plant caused by the presence of light.
In contrast to ferns, lower plants and many naked samers , the presence of light also influences the formation of the more cloudy ones. While the former do not show any differences in their shape, regardless of whether they grow under light or in complete darkness, covered plants that are grown in the dark show clear deviations from plants of the same age grown under light ( scotomorphogenesis ). They have very elongated internodes and petioles, at the same time the blade is reduced in size. The synthesis of pigments such as chlorophyll or anthocyanin does not take place, vascular bundles and strengthening elements are hardly formed. This process (known as gelatinization ) is ecologically used so that the plant uses all of its strength to bring the organs of assimilation to light.
