In reference to the types sexual reproduction in organisms Select the wrong statement :

Options

A. Isogametes are similar in structure, function and behaviour
B. Anisogametes differ either in structure, function and behaviour
C. In oomycetes female gamete is smaller and motile, while male gamete is larger and non-motile
D. Chlamydomonas exhibits both isogamy and anisogamy and Fucus shows oogamy

Explanation

To solve the question regarding the types of sexual reproduction in organisms and to identify the wrong statement, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Sexual Reproduction**:
- Sexual reproduction involves two parents and the formation of gametes (sperm and egg). It can be categorized into three main types: isogamy, anisogamy, and oogamy.

2. **Identify Types of Gametes**:
- **Isogamy**: Involves gametes that are morphologically similar. Example: Chlamydomonas.
- **Anisogamy**: Involves gametes that are different in structure and function. The male gamete is usually smaller and motile, while the female gamete is larger and non-motile.
- **Oogamy**: Involves a large, non-motile female gamete and a small, motile male gamete.

3. **Examine Each Statement**:
- **Statement 1**: Isogametes are similar in function, structure, and behavior.
- This is true.
- **Statement 2**: Anisogametes are different in structure, behavior, and function.
- This is also true.
- **Statement 3**: In oomycetes, the female gamete is smaller and motile while the male gamete is larger and non-motile.
- This is false. In oomycetes, the female gamete is larger and non-motile, while the male gamete is smaller and motile.
- **Statement 4**: Chlamydomonas exhibits both isogamy and anisogamy, and Fucus shows oogamy.
- This statement is true.

4. **Identify the Wrong Statement**:
- Based on the analysis, Statement 3 is incorrect. Therefore, it is the wrong statement in reference to the types of sexual reproduction in organisms.

5. **Conclusion**:
- The wrong statement is: "In oomycetes, the female gamete is smaller and motile while the male gamete is larger and non-motile."

### Final Answer:
The wrong statement is Statement 3.
