Fertilized embryo sac is shown in the diagram P and Q are results of …....and …..... , respectively .

Options

A. double Fertilization , syngamy
B. triple fusion , syngamy
C. syngamy , parthenocarpy
D. syngamy , triple fusion

Answer

To solve the question regarding the fertilized embryo sac and the results labeled as P and Q, we need to understand the processes involved in fertilization in plants. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Identify the Components**:
- In the diagram, P represents the zygote and Q represents the endosperm.

2. **Understanding Zygote Formation**:
- The zygote (P) is formed when the male gamete (sperm) fertilizes the female gamete (egg). This process is known as **syngamy**.

3. **Understanding Endosperm Formation**:
- The endosperm (Q) is formed when the second male gamete fuses with the two polar nuclei present in the embryo sac. This process is known as **triple fusion**.

4. **Double Fertilization**:
- The entire process that includes both syngamy (formation of the zygote) and triple fusion (formation of the endosperm) is referred to as **double fertilization**.

5. **Conclusion**:
- Therefore, P is the result of **syngamy** (formation of the zygote) and Q is the result of **triple fusion** (formation of the endosperm).

### Final Answer:
- P is the result of **syngamy** and Q is the result of **triple fusion**.
