Gibberellins are widely reported from

Options

A. algae and fungi
B. fungi and higher plants
C. bacteria and yeast
D. fungi and bacteria

Answer

**Step-by-Step Solution:**

1. **Understanding Gibberellins**: Gibberellins are a class of plant hormones that play a crucial role in promoting growth and development in plants. They are known to regulate various physiological processes, including stem elongation, seed germination, and flowering.

2. **Identifying Sources of Gibberellins**: The question asks where gibberellins are widely reported from. It is essential to consider the organisms from which these plant growth regulators are derived.

3. **Evaluating the Options**:
- **Option A: Algae and fungi**: While fungi are known to produce gibberellins, algae are not typically associated with gibberellin production.
- **Option B: Fungi and higher plants**: This option is plausible as both fungi and higher plants are known to produce gibberellins.
- **Option C: Bacteria and yeast**: There is limited evidence of gibberellin production in these organisms.
- **Option D: Fungi and bacteria**: Similar to option C, bacteria are not widely recognized for gibberellin production.

4. **Conclusion**: Based on the evaluation of the options, the most accurate answer is **B: Fungi and higher plants**. Gibberellins have been widely reported from these two groups of organisms.

5. **Final Answer**: Gibberellins are widely reported from **B. Fungi and higher plants**.
