Question
Which plant hormone is primarily responsible for cell elongation?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Auxins are a group of plant hormones that play a crucial role in cell elongation, particularly in shoots, contributing to phototropism and gravitropism. Cytokinins primarily promote cell division, gibberellins promote stem elongation and seed germination, and abscisic acid is involved in dormancy and stress responses.
Hint
This hormone is often associated with growth responses that involve cell stretching, such as bending towards light.
