Select an incorrect statement for Cytotaxonomy.

Options

A. Information about the mode of pairing of chromosomes during meiosis is used by the taxonomists to understand the relationship between the species.
B. Number of chromosomes is constant in the species
C. Woody plants have larger chromosomes than the herbaceous plants.
D. Uses cytological information on cell, chromosomal number, structure and behaviour of chromosomes during meiosis

Answer

To solve the question regarding the incorrect statement for cytotaxonomy, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Cytotaxonomy**:
- Cytotaxonomy is a branch of taxonomy that classifies organisms based on cytological (cellular) information, particularly focusing on chromosomes.

2. **Identify Key Aspects of Cytotaxonomy**:
- It utilizes chromosome number, structure, and behavior.
- It examines how chromosomes pair during meiosis (the process of cell division that reduces chromosome number).

3. **Evaluate Statements**:
- **Statement 1**: "The mode of pairing of chromosomes during meiosis is used by taxonomists to understand the relation between species."
- This statement is correct as it reflects how cytotaxonomy uses chromosome behavior.
- **Statement 2**: "The number of chromosomes is constant in our species."
- This statement is also correct, as each species has a characteristic number of chromosomes.
- **Statement 3**: "Woody plants have larger chromosomes than herbaceous plants."
- This statement is incorrect. In fact, herbaceous plants typically have larger chromosomes than woody plants.

4. **Conclusion**:
- The incorrect statement regarding cytotaxonomy is the third one: "Woody plants have larger chromosomes than herbaceous plants."

### Final Answer:
The incorrect statement for cytotaxonomy is: "Woody plants have larger chromosomes than herbaceous plants."
