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 indicated by P and Q, we will break down the processes involved in fertilization in flowering plants (angiosperms) step by step.

### Step-by-Step Solution:

1. **Understanding the Fertilized Embryo Sac**:
- The embryo sac is the female gametophyte in flowering plants. It contains the egg cell, which is the female gamete.

2. **Identifying the Processes**:
- In flowering plants, fertilization involves two key processes known as double fertilization. This includes:
- **Syngamy**: The fusion of one male gamete with the egg cell to form the zygote.
- **Triple Fusion**: The fusion of the second male gamete with two polar nuclei to form the endosperm.

3. **Analyzing the Diagram**:
- In the diagram, point P represents the **Zygote**, which is formed from the fusion of the male gamete and the egg cell (syngamy).
- Point Q represents the **Endosperm**, which is formed from the fusion of the second male gamete with the polar nuclei (triple fusion).

4. **Concluding the Results**:
- Therefore, P (Zygote) is the result of **Syngamy**.
- Q (Endosperm) is the result of **Triple Fusion**.

5. **Final Answer**:
- P and Q are results of **Syngamy** and **Triple Fusion**, respectively.
