Egg apparatus of angiosperm consists of

Options

A. an egg cell and two antipdals
B. an egg cell and two synergids
C. an egg cell and two polar nuclei
D. an egg and the central cell

Answer

To answer the question regarding the composition of the egg apparatus in angiosperms, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Egg Apparatus**: The egg apparatus in angiosperms is a part of the embryo sac, which is crucial for fertilization. It consists of specific cells that play a role in the reproductive process.

2. **Identifying the Components**: The egg apparatus is made up of:
- **One Egg Cell**: This is the female gamete that will fuse with a male gamete during fertilization.
- **Two Synergids**: These cells are located near the egg cell and help guide the pollen tube to the egg for fertilization.

3. **Differentiating from Other Cells**: It is important to distinguish the egg apparatus from other cells present in the embryo sac:
- **Antipodal Cells**: These are three cells located at the opposite end of the embryo sac (chalaza end) and are not part of the egg apparatus.
- **Central Cell**: This cell contains two polar nuclei and is involved in forming the endosperm after fertilization, but it is not part of the egg apparatus.

4. **Conclusion**: Based on the components identified, the egg apparatus consists of one egg cell and two synergids. Therefore, the correct answer to the question is:
- **One Egg Cell and Two Synergids**.

### Final Answer:
The egg apparatus of angiosperms consists of **one egg cell and two synergids**.
