Radicle is produced from

Options

A. Apical octant
B. Micropylar octant
C. Vegetative cell
D. Hypophysis.

Answer

To answer the question "Radicle is produced from," we will analyze the options provided and determine the correct one step by step.

### Step-by-Step Solution:

1. **Understanding the Radicle**: The radicle is the part of a seed that develops into the primary root of the plant. It is crucial for anchoring the plant and absorbing water and nutrients from the soil.

2. **Evaluating the Options**:
- **Option A: Apical Octant**: The apical octant is responsible for the development of the embryo and cotyledons. It does not produce the radicle.
- **Option B: Micropilar End**: This is the end of the seed where the pollen tube enters. It is associated with the development of the embryo but does not directly produce the radicle.
- **Option C: Vegetative Cell**: Vegetative cells in pollen grains help in the formation of the pollen tube. They do not produce the radicle.
- **Option D: Hypophysis**: The hypophysis is the topmost cell of the suspensor in the developing embryo. It is known to develop into the radicle and the root cap.

3. **Conclusion**: Based on the analysis, the hypophysis is the correct part from which the radicle is produced. Therefore, the answer is **Option D: Hypophysis**.
