Cytokinins are generally

Options

A. Acids
B. Aminopurines
C. Phenols
D. Glucosides.

Answer

**Step-by-Step Solution:**

1. **Understanding Cytokinins**: Cytokinins are a class of plant hormones that play a crucial role in promoting cell division and growth in plants. They are known to influence various physiological processes.

2. **Identifying the Nature of Cytokinins**: Cytokinins are classified as plant growth regulators. They are generally basic in nature, which means they have a tendency to accept protons (H+ ions) in a solution.

3. **Recognizing the Chemical Structure**: The first discovered cytokinin is an amino purine. Amino purines are compounds that contain a purine base with an amino group attached.

4. **Examples of Cytokinins**: The first discovered cytokinin is kinetin, which is derived from amino purines. Another example is zeatin, which is an adenine derivative.

5. **Conclusion**: Based on the information provided, the correct classification of cytokinins is that they are generally amino purines.

**Final Answer**: Cytokinins are generally amino purines.
