Which statements is not correct for gastrulation

Options

A. formation of archenteron
B. Cell division stops
C. Oxidation reaction increase
D. Elongation of embryo starts

Answer

**Step-by-Step Solution:**

1. **Understanding Gastrulation**: Gastrulation is a crucial phase in embryonic development where the single-layered blastula transforms into a multi-layered structure called the gastrula. This process involves significant cellular movements and differentiation.

2. **Identifying the Statements**: The question asks which statement is not correct regarding gastrulation. The options provided are:
- Formation of archenteron
- Cell division stops
- Oxidation reaction increases
- Elongation of embryo starts

3. **Analyzing Each Statement**:
- **Formation of Archenteron**: This is correct. The archenteron, which is the primitive gut, forms during gastrulation.
- **Cell Division Stops**: This is incorrect. Cell division does not stop during gastrulation; in fact, it continues as cells migrate and differentiate.
- **Oxidation Reaction Increases**: This is correct. During gastrulation, metabolic activities, including oxidation reactions, are heightened.
- **Elongation of Embryo Starts**: This is correct. The elongation of the embryo is a key feature of gastrulation.

4. **Conclusion**: The statement that is not correct for gastrulation is "cell division stops." This is the only statement that does not accurately describe the gastrulation process.

**Final Answer**: The statement that is not correct for gastrulation is "cell division stops."
