  1. Mutated
  2. Embolised
  3. Etiolated

Solution

Etiolation is a phenomenon present in plants that are due to complete or partial absence of light. Skotomorphogenesis is the other name seed germination in absence of light, which leads to etiolation.
Etiolation causes some typical changes in the morphology of the plant (seedling). This happens primarily due to the likelihood of reaching the source of light.
