Etiolation
From Wikipedia, the free encyclopedia
Etiolation is a plant response to stimuli. When plant seeds are grown in insufficient light, either in partial or complete absence of light, the seedlings will have long, weak stems, smaller and fewer leaves because of longer internodes, and a pale yellow color (chlorosis). This is due to a lack of chlorophyll. The plant's increase in height helps it to reach a possible source of light faster.
