Which one is wrongly matched ?

Options

A. Auxins - to grow
B. Gibberellins-Gibberella fujikuroi
C. Cytokinins - Herring sperm DNA
D. ABA - flowering hormone.

Answer

To determine which option is wrongly matched in the context of plant hormones, we can analyze each hormone and its associated function:

1. **Auxin**: This hormone is indeed associated with growth, particularly in promoting cell elongation in shoots and roots. Therefore, this match is correct.

2. **Gibberellin**: Gibberellins are known for their role in promoting stem elongation and seed germination. They are produced in various fungi and plants, and their function in elongating internodes is accurate. Thus, this match is also correct.

3. **Cytokinin**: Cytokinins are involved in cell division and growth. They are derived from herring sperm DNA and are indeed responsible for promoting cell division. This match is correct as well.

4. **Abscisic Acid (ABA)**: Abscisic acid is primarily known for its role in promoting dormancy and inhibiting growth. It is not responsible for flowering; rather, it helps in processes like seed dormancy and stress responses. Therefore, this match is incorrect.

Based on this analysis, the wrongly matched option is:

**Answer**: Abscisic Acid is wrongly matched as a flowering hormone.
