Question

Which acid is responsible for enlargement of ovary into fruit?

• A. Auxin
• B. Cytokinin
• C. Gibberellin
• D. Abscisic acid

Hint:

Auxins are involved not only in fruit development but also in various growth processes like phototropism, gravitropism, and apical dominance. Understanding the roles of plant hormones is essential for improving agricultural practices, especially in fruit production.

Answer 1

The Correct Option is A

Auxins are a class of plant hormones that play a crucial role in the regulation of plant growth and development. One of the primary functions of auxins is to promote the enlargement of the ovary into fruit after fertilization. This process is called fruit set and is triggered by the production of auxin in the fertilized ovule. Auxins help in: - Stimulating cell elongation in the ovary, leading to fruit enlargement. - Regulating the synthesis of other hormones such as gibberellins, which also play a role in fruit development. - Maintaining the growth of tissues that are essential for fruit formation. Thus, the correct answer is Auxin.
