Blastopore is the pore of :-

Options

A. Archenteron
B. Blastocoel
C. Coelom
D. acoelom

Answer

**Step-by-Step Solution:**

1. **Understanding the Concept of Blastopore**:
- The blastopore is an important structure that forms during the early stages of embryonic development. It is specifically associated with the process of gastrulation.

2. **Identifying the Stages of Embryonic Development**:
- Initially, an embryo forms a structure called the blastula, which is a hollow sphere of cells.
- Following the blastula stage, the embryo undergoes gastrulation, where it transforms into a gastrula, which has three distinct layers: ectoderm, mesoderm, and endoderm.

3. **Defining Gastrulation**:
- Gastrulation is the process during which the single-layered blastula is reorganized into a multi-layered structure (the gastrula). This is a critical phase in embryonic development.

4. **Formation of the Blastopore**:
- During gastrulation, the blastopore forms as an opening that leads into the archenteron, which is the primitive gut of the embryo.

5. **Identifying the Correct Answer**:
- The blastopore is specifically the pore of the archenteron, which is the gut of the embryo. Therefore, the correct answer to the question is that the blastopore is the pore of the archenteron.

**Final Conclusion**:
- The blastopore is the pore of the archenteron.
