When a spore mother cell produces more than 4 spores, it refers to:

Options

A. Polysinphony
B. Polyspermy
C. Polyspory
D. Poly embryony

Answer

To solve the question "When a spore mother cell produces more than 4 spores, it refers to:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- First, we need to know what a spore mother cell is. A spore mother cell, also known as a microspore mother cell, undergoes meiosis to produce spores.

2. **Normal Production of Spores**:
- Typically, a spore mother cell produces four spores through the process of meiosis. This is known as microsporogenesis, resulting in a structure called a microspore tetrad.

3. **Identifying the Condition of More Than Four Spores**:
- The question specifically asks about the condition when a spore mother cell produces more than four spores. This is not the typical outcome and indicates a specific phenomenon.

4. **Evaluating the Options**:
- The options provided are:
- A) Polysiphony
- B) Polyspermy
- C) Polyspory
- D) Polyembryony
- We need to analyze each term:
- **Polysiphony** refers to the formation of more pollen tubes.
- **Polyspermy** refers to fertilization by more than one sperm.
- **Polyembryony** refers to the formation of multiple embryos from a single fertilized ovum.
- **Polyspory** refers to the condition where more than four spores are produced.

5. **Conclusion**:
- Based on the definitions and understanding, when a spore mother cell produces more than four spores, this condition is referred to as **polyspory**. Therefore, the correct answer is option C) Polyspory.

### Final Answer:
C) Polyspory
