The "endosperm" of a gymnosperm represent :-

Options

A. Gametophytic tissue
B. Sporophytic tissue
C. Tissue formed by double fertilization
D. Polyploid tissue

Answer

To answer the question "The 'endosperm' of a gymnosperm represents:", we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Endosperm**:
- Endosperm is a tissue that provides nutrition to the developing embryo in seeds. It is crucial for the growth and development of the embryo.

2. **Identify the Nature of Endosperm in Gymnosperms**:
- In gymnosperms, the endosperm is haploid (1N). This is an important distinction because it differs from angiosperms, where the endosperm is typically triploid (3N) due to double fertilization.

3. **Recognize the Developmental Role of Endosperm**:
- In gymnosperms, the endosperm develops into a structure known as the prothallus, which is the gametophytic stage of the plant. This stage is involved in producing female gametes.

4. **Differentiate Between Gymnosperms and Angiosperms**:
- Gymnosperms do not undergo double fertilization, which is a process that occurs in angiosperms. This process is responsible for the formation of the triploid endosperm in angiosperms.

5. **Evaluate the Options Given**:
- Option A: Gametophytic tissue - This is correct because the endosperm in gymnosperms is haploid and gives rise to the prothallus, which is a gametophyte.
- Option B: Sporophytic tissue - This is incorrect as the endosperm is not sporophytic.
- Option C: Tissue formed by double fertilization - This is incorrect as double fertilization does not occur in gymnosperms.
- Option D: Polyploid tissue - This is incorrect because the endosperm in gymnosperms is haploid, not polyploid.

6. **Conclusion**:
- Based on the analysis, the correct answer is **Option A: Gametophytic tissue**, as it accurately describes the nature of the endosperm in gymnosperms.

### Final Answer:
**The endosperm of a gymnosperm represents: Gametophytic tissue.**
