A few normal tomato seedlings were kept in a dark room. After a few days they were found to have become white-coloured like albinos. Which of the following terms will you use to describe them?
Mutated
Embolised
Etiolated
Defoliated
Etiolation is a process in which flowering plants are grown in partial or complete absence of light.
Etiolation is mainly characterized by long and weak stems and smaller, sparse pale yellow color of leaves due to the longer internodes. Thus due to this tomato seedling became white coloured. Hence, the correct answer is option 3.
