Blastopore is the pore of :-

Options

A. Archenteron
B. Blastocel
C. Coelom
D. A.C

Answer

To solve the question "Blastopore is the pore of:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Blastopore**:
- The blastopore is an opening that forms during the early stages of embryonic development, specifically during the process of gastrulation.

2. **Identify the Structure Associated with Blastopore**:
- During gastrulation, the blastopore is formed from the invagination of the blastula. This invagination leads to the formation of a structure known as the archenteron.

3. **Define Archenteron**:
- The archenteron is the primitive gut that forms during the development of an embryo. It eventually gives rise to the gastrointestinal tract.

4. **Analyze the Options Given**:
- a. Archenteron
- b. Blastocoel
- c. Coelom
- d. None of the above

5. **Evaluate Each Option**:
- **Archenteron**: Correct, as the blastopore is the opening of the archenteron.
- **Blastocoel**: Incorrect, as this is the cavity within the blastula, not the structure associated with the blastopore.
- **Coelom**: Incorrect, as the coelom is a body cavity that develops later in some organisms.
- **None of the above**: Incorrect, since we have identified the correct answer.

6. **Conclusion**:
- Based on the definitions and relationships, the blastopore is indeed the pore of the archenteron.

### Final Answer:
The blastopore is the pore of **Archenteron** (Option A).
