Can someone write a paragraph explaining Etiolation. PLEASEEEE
Anit [1.1K]

Etioliation means that you water plants that are planted in an area with little to no sunlight. This results in weak stems, smaller leaves, yellow color, etc. The seedlings that are grown in the dark are known as "skotomorphogenesis." Etiolation comes from something called "Auxin's" and Auxin's are moved from the top of the plant to the bottom which creates lateral buds. Typically, etiliation results in the chances being raised for the plant to receive sunlight but causes underiable symptoms.

Best of Luck!
