Read the following statements on plant growth and development.
A. Parthenocarpy can be induced by auxins.
B. Plant growth regulators can be involved in promotion as well as inhibition of growth.
C. Dedifferentiation is a pre-requisite for re differentiation.
D. Abscisic acid is a plant growth promoter.
E. Apical dominance promotes the growth of lateral buds.
Choose the option with all correct statements. 

The correct answer is 1) A, B, C only

Concept:

• Plant growth and development are regulated by various plant growth regulators (PGRs) such as auxins, gibberellins, cytokinins, abscisic acid, and ethylene. These regulators can either promote or inhibit plant growth depending on their type and concentration.
• Processes like parthenocarpy, dedifferentiation, and redifferentiation are fundamental aspects of plant development.
• Understanding the roles of PGRs and the processes involved in plant growth is critical to solving the given question.

Explanation:

• A. Parthenocarpy can be induced by auxins: Parthenocarpy is the development of fruit without fertilization, leading to seedless fruits. Auxins, along with gibberellins, can artificially induce parthenocarpy by mimicking the hormonal changes that occur after fertilization. This statement is correct.
• B. Plant growth regulators can be involved in promotion as well as inhibition of growth: Plant growth regulators such as auxins, gibberellins, and cytokinins promote growth, while others like abscisic acid and ethylene can inhibit growth. Thus, PGRs can have dual roles depending on the physiological context. This statement is correct.
• C. Dedifferentiation is a pre-requisite for redifferentiation: Dedifferentiation refers to the process where mature cells regain the ability to divide and form callus tissue. These dedifferentiated cells can then undergo redifferentiation to develop into specific tissues or organs. This is an essential step in plant tissue culture. This statement is correct.

Incorrect Statements:

• D. Abscisic acid is a plant growth promoter: This statement is incorrect. Abscisic acid (ABA) is primarily a growth inhibitor. It plays a significant role in stress responses such as closing stomata during water stress and inducing dormancy in seeds and buds. It is not a growth promoter.
• E. Apical dominance promotes the growth of lateral buds: This statement is incorrect. Apical dominance refers to the suppression of lateral bud growth due to the activity of the apical bud, which produces auxins. This phenomenon inhibits the growth of lateral buds rather than promoting it.

Summary:

• The correct statements are A, B, and C, which are included in option 1.
• Statements D and E are incorrect because abscisic acid is a growth inhibitor, and apical dominance suppresses rather than promotes lateral bud growth.
