Question
Which hormone is primarily responsible for cell elongation in plants
Correct Answer
Option D is the correct answer.
Detailed Explanation
Auxins are a class of plant hormones that play a crucial role in cell elongation, particularly in stems and coleoptiles. They promote growth by increasing the plasticity of cell walls. Ethylene is involved in fruit ripening and senescence. Cytokinins promote cell division. Abscisic acid is involved in dormancy and stress responses.
Hint
This plant hormone is well-known for its role in apical dominance and the bending of plants towards light.
