In most of the following plants , seeds does not contain any remnant of

Options

A. outer integument
B. inner integument
C. nucellus
D. micropyle

Answer

To solve the question regarding which remnant is not found in the seeds of most plants, we can analyze the four options provided:

1. **Outer Integument**: The outer integument refers to the outer layer of the ovule, which eventually becomes part of the seed coat. This structure is present in seeds, so it does contain remnants of the outer integument.

2. **Inner Integument**: The inner integument also contributes to the seed coat. Like the outer integument, remnants of the inner integument are found in seeds. Therefore, this option can also be ruled out.

3. **Nucleus**: The nucleus in the context of seeds refers to the endospermic nucleus, which can develop into perisperm, a nutritive tissue. In many angiosperms, the perisperm is utilized during seed development, and remnants of it may not be present in the mature seeds. Thus, this option is a strong candidate.

4. **Micropyle**: The micropyle is a small opening in the seed coat that allows for the entry of water and gases. It is a remnant of the ovule and is typically present in seeds.

Based on this analysis, the remnant that is not typically found in the seeds of most plants is the **Nucleus**.

### Step-by-Step Solution:
1. Identify the four components mentioned in the question: Outer Integument, Inner Integument, Nucleus, and Micropyle.
2. Analyze the function and presence of each component in seeds.
3. Determine that the Outer Integument and Inner Integument are present in seeds.
4. Recognize that the Micropyle is also present in seeds.
5. Conclude that the Nucleus, which can develop into perisperm, is often not found in mature seeds.
6. Therefore, the answer is that seeds do not contain any remnant of the **Nucleus**.
