Among the metazoans the embryonic divergence begins from

Options

A. Zygote
B. Morula
C. Blastula
D. Gastrula

Answer

To answer the question "Among the metazoans, the embryonic divergence begins from," we need to analyze the provided options and understand the developmental stages of metazoans (multicellular eukaryotic organisms).

### Step-by-Step Solution:

1. **Understanding Metazoans**:
- Metazoans are multicellular eukaryotic organisms. They undergo various stages of embryonic development after fertilization.

2. **Analyzing the Options**:
- **Gycote**: This term seems to be a misspelling of "zygote." A zygote is the fertilized egg formed by the fusion of male and female gametes. It is a unicellular stage and does not represent embryonic divergence.
- **Modula**: This likely refers to "morula," which is a solid ball of cells resulting from the cleavage of the zygote. It is an early stage of development but does not signify the beginning of embryonic divergence.
- **Blastula**: The blastula is a hollow sphere of cells that forms after the morula stage. While it is an important stage in development, it does not represent embryonic divergence.
- **Gastrola**: The gastrula is the stage that follows the blastula. It is characterized by the formation of germ layers (ectoderm, mesoderm, and endoderm) and marks the beginning of embryonic divergence, where different cell types begin to form.

3. **Conclusion**:
- Among the options provided, the embryonic divergence in metazoans begins from the **gastrola** stage.

### Final Answer:
The embryonic divergence among metazoans begins from the **gastrola** stage.
