In bitegmic type of ovule, nucellus is ______, and the number of integuments is ________.

Options

A. Poorly developed, two
B. Well developed, two
C. Poorly developed, one
D. Well developed, one

Answer

To solve the question regarding the characteristics of the bitegmic type of ovule, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Nucellus**: This is the central part of the ovule, which contains the embryo sac and is responsible for nourishing the developing embryo.
- **Integuments**: These are the protective layers that surround the nucellus. They develop from the ovule and play a crucial role in protecting the developing seed.

2. **Identifying the Type of Ovule**:
- The question specifies the "bitegmic" type of ovule. This term indicates that there are two integuments surrounding the nucellus.

3. **Characteristics of Bitegmic Ovule**:
- In a bitegmic ovule, the integuments are typically well-developed. This means they are fully formed and provide adequate protection to the nucellus and the embryo sac within.

4. **Conclusion**:
- Based on the definitions and characteristics of a bitegmic ovule, we can conclude that:
- The nucellus is **well developed**.
- The number of integuments is **2**.

### Final Answer:
In bitegmic type of ovule, nucellus is **well developed**, and the number of integuments is **2**.
