In gymnosperms, the nucellus is protected by envelops and the composite structure is called?

Answer

To answer the question, "In gymnosperms, the nucellus is protected by envelopes and the composite structure is called?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Components**:
- In gymnosperms, the nucellus is a part of the ovule. The ovule is the structure that develops into a seed after fertilization.

2. **Identifying the Protective Structures**:
- The nucellus is surrounded by protective layers known as integuments. These integuments are the outer layers that safeguard the nucellus.

3. **Defining the Composite Structure**:
- When we refer to the composite structure that includes the nucellus and its protective layers (integuments), we are talking about the ovule as a whole.

4. **Conclusion**:
- Therefore, in gymnosperms, the nucellus is protected by envelopes (integuments), and the composite structure formed by the nucellus and integuments is called the **ovule**.

### Final Answer:
The composite structure is called the **ovule**.
