In A Quiz Competition, You Are Asked A Question Where You Have To Cho...
Abscisic acid is a plant hormone which functions mainly as a growth inhibitor. Abscisic acid promotes the dormancy in seeds and buds. It also promotes the closing of stomata. Abscisic Acid promotes the wilting and falling of leaves which is called “abscission”.

Incorrect Statement about Plant Hormones
The correct answer to the quiz question is option 'B' - Abscisic acid which promotes the opening of stomata and promotes the dormancy in seeds and buds. This statement is incorrect because abscisic acid (ABA) actually promotes the closure of stomata and inhibits the growth of seeds and buds.
Explanation
Plant hormones are chemical substances produced by plants that regulate their growth, development, and response to environmental stimuli. There are five main types of plant hormones: auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Each hormone has a specific function and can affect different aspects of plant growth and development.
Control and Coordination in Plants
Control and coordination in plants is the process by which plants respond to different stimuli such as light, gravity, touch, and temperature. Plant hormones are involved in this process by regulating the growth and development of various plant organs, tissues, and cells.
Functions of Plant Hormones
The functions of different plant hormones are as follows:
1. Auxins: Auxins are plant hormones that promote cell enlargement and cell differentiation in plants. They also play a role in phototropism, gravitropism, and apical dominance.
2. Gibberellins: Gibberellins help in breaking the dormancy in seeds and buds. They also promote stem elongation and fruit development in plants.
3. Cytokinins: Cytokinins promote cell division and delay senescence in plants. They also play a role in apical dominance and root growth.
4. Abscisic acid: Abscisic acid (ABA) inhibits the growth of seeds and buds and promotes the closure of stomata. It also plays a role in drought tolerance and stress response in plants.
5. Ethylene: Ethylene is involved in fruit ripening, leaf abscission, and senescence in plants. It also plays a role in response to biotic and abiotic stress.
Conclusion
In conclusion, the statement that abscisic acid promotes the opening of stomata and promotes the dormancy in seeds and buds is incorrect. Abscisic acid actually promotes the closure of stomata and inhibits the growth of seeds and buds. Plant hormones have different functions and play a vital role in the control and coordination of plant growth and development.
