Choose the incorrect statement form the following

Options

A. Cytokinis show specific effect on cytokinesis
B. ABA is antagonistic phytohomone to Gibberellic acids
C. Natural cytokinins are sythesized in root apices only
D. Ethylene increase absorption surface of root system

Answer

To solve the question of identifying the incorrect statement among the given options, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Examine Option A**:
- Statement: "Cytokinesis shows a specific effect of cytokinesis."
- Analysis: This statement is correct as it refers to the process of cytokinesis, which is the division of the cytoplasm during cell division.

2. **Examine Option B**:
- Statement: "ABA (Abscisic Acid) is an antagonistic phytohormone."
- Analysis: This statement is also correct. Abscisic Acid is known to be an antagonistic hormone to gibberellins, which promote growth.

3. **Examine Option C**:
- Statement: "Natural cytokinesis are synthesized in root apices only."
- Analysis: This statement is incorrect. Natural cytokinins are primarily synthesized in the shoot apices, not the root apices. Therefore, this is the incorrect statement.

4. **Examine Option D**:
- Statement: "Ethylene increases the absorption surface of the root system."
- Analysis: This statement is correct. Ethylene does play a role in enhancing the root system's absorption capabilities.

### Conclusion:
After analyzing all the options, we find that **Option C** is the incorrect statement.

### Final Answer:
The incorrect statement is **Option C**: "Natural cytokinesis are synthesized in root apices only."
