Question

What is the full form of IAA?

Answer 1

The full form of IAA is Indole-3-Acetic Acid.

Explanation:

Indole-3-Acetic Acid (IAA) is a naturally occurring plant hormone that belongs to the group of auxins. Auxins are responsible for regulating various growth and developmental processes in plants. IAA plays a crucial role in cell elongation, growth regulation, and differentiation, particularly in the growth of roots and shoots.

Function of IAA:

• Promotes cell elongation in plant tissues.
• Regulates the growth of roots and shoots.
• Involved in phototropism (growth in response to light) and gravitropism (growth in response to gravity).
• Stimulates the formation of lateral roots and the development of fruit.

Conclusion:

Indole-3-Acetic Acid is an essential plant hormone that regulates various aspects of plant growth and development, particularly in the elongation of cells and the formation of structures like roots and shoots.
