De etiolation Notes:
De-etiolation, is a series of physiological and biochemical changes a plant shoot undergoes when emerging from the ground or in response to light after a period of insufficient light exposure. This process is known informally as greening. These changes that are triggered in the plants shoots or already formed leaves and stems occur in preparation for photosynthesis. Some of the changes that occur include, Inhibition of hypocotyl lengthening, stimulation of cotyledon expansion, opening of the apical hook etc.
