Generally number of integuments in the ovule of angiosperms and gymnosperms is

Options

A. One and two
B. One and one
C. Two and one
D. Two and two

Answer

To solve the question regarding the number of integuments in the ovule of angiosperms and gymnosperms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Integuments**:
- Integuments are protective layers that surround the ovule in seed plants. They play a crucial role in the development and protection of the ovule.

2. **Identify the Types of Plants**:
- The question involves two types of seed plants: angiosperms and gymnosperms.

3. **Analyze Gymnosperms**:
- Gymnosperms typically have a single integument surrounding the ovule. This means they are described as "unitegmic."

4. **Analyze Angiosperms**:
- Angiosperms, on the other hand, usually have two integuments surrounding the ovule. This characteristic makes them "bitegmic."

5. **Combine the Findings**:
- From the analysis, we conclude that angiosperms have two integuments, while gymnosperms have one integument.

6. **Select the Correct Answer**:
- Therefore, the correct answer to the question is: **2 and 1** (2 integuments in angiosperms and 1 integument in gymnosperms).

### Final Answer:
The number of integuments in the ovule of angiosperms and gymnosperms is **2 and 1**, respectively.
