Absence of light during plant growth, result in pale colour seeds known as:

  1. Photogenesis
  2. Phototonic effect
  3. Etiolation
  4. Photomophogenesis
Correct Answer: Option(c)
Solution: Seedlings grown in the dark develop long hypocotyl and their cotyledons remain closed around the epicotyl in an apical hook. This is referred to as skotomorphogenesis or etiolation. Etiolated seedlings are yellowish in color as chlorophyll synthesis and chloroplast development depend on light
So the correct answer is 'Etiolation'.
