In some plants,the female gamete develops into embryo without fertilisation. This phenomenoun is known as

Options

A. Autogamy
B. Parthenocarpy
C. Syngamy
D. Parthenogenesis

Answer

To solve the question regarding the phenomenon where the female gamete develops into an embryo without fertilization, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept**:
- In sexual reproduction, the typical process involves fertilization, where male and female gametes unite to form a zygote, which then develops into an embryo.

2. **Identifying the Phenomenon**:
- The question specifies a situation where the female gamete develops into an embryo without the need for fertilization. This indicates a process that bypasses the usual fertilization step.

3. **Defining the Terms**:
- The options provided are:
- Autogami: A form of self-pollination.
- Partheno: This is not a complete term in this context.
- Carpi: Not relevant to the context.
- Syngami: Another term for fertilization.
- Parthenogenesis: A process where an embryo develops from an unfertilized egg.

4. **Choosing the Correct Answer**:
- Among the options, "Parthenogenesis" is the correct term that describes the development of an embryo from a female gamete without fertilization. This process occurs in various organisms, including some plants.

5. **Conclusion**:
- Therefore, the phenomenon where the female gamete develops into an embryo without fertilization is known as **Parthenogenesis**.

### Final Answer:
**Parthenogenesis**
