Options

A. Acetabularia
B. Maize
C. Pea
D. Neurospora

Answer

To answer the question regarding the role of the nucleus in the morphology of plants and who first discovered it, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the discovery of the role of the nucleus in plant morphology. We need to identify the scientist who first made this discovery.

2. **Identifying the Organism Used**: The organism that was pivotal in this discovery is Acetabularia, a genus of green algae. This organism was used in experiments to understand the role of the nucleus.

3. **Researching Historical Context**: In the early days of cell biology, significant experiments were conducted on Acetabularia, particularly focusing on nuclear transplantation and its effects on cellular development.

4. **Identifying the Scientist**: The scientist who conducted these experiments and made the discovery regarding the nucleus's role in plant morphology is Hammerling.

5. **Conclusion**: Therefore, the role of the nucleus in the morphology of plants was first discovered by Hammerling through his work with Acetabularia.
