Answer

Function of IAA (Indole Acetic Acid)

IAA, or indole acetic acid, is a type of plant hormone that plays a crucial role in the growth and development of plants. It is the most common and important natural auxin found in plants. Let's delve deeper into the functions of IAA:

1. Cell Division and Elongation
IAA is responsible for promoting cell division and elongation in plants. It helps in the growth of roots, stems, and leaves by stimulating the cells to divide and elongate, leading to overall plant growth.

2. Apical Dominance
IAA helps in maintaining apical dominance in plants. It inhibits the growth of lateral buds, directing the plant's energy towards the growth of the main stem or shoot.

3. Root Development
IAA plays a crucial role in root development. It helps in root initiation, growth, and branching by promoting cell division and elongation in the root tissues.

4. Fruit Development
IAA influences fruit development by regulating cell division and expansion in the fruit tissues. It helps in fruit setting, growth, and ripening processes.

5. Tropisms
IAA is involved in various plant tropisms like phototropism, gravitropism, and thigmotropism. It helps plants respond to light, gravity, and touch stimuli by regulating the growth of plant organs towards or away from the stimulus.

6. Senescence and Abscission
IAA also plays a role in senescence (aging) and abscission (shedding) of plant organs. It regulates the process of leaf senescence and the abscission of leaves, flowers, and fruits.

In conclusion, IAA is a versatile plant hormone that regulates various aspects of plant growth and development, making it essential for the overall health and productivity of plants.
