In most of the following plants , seeds does not contain any remnant of
(a) outer integument
(b) inner integument
(c) nucellus
(d) micropyle

Options

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

Answer

To solve the question, we need to determine which part of the seed does not have any remnant in most plants. The options given are:

(a) outer integument
(b) inner integument
(c) nucellus
(d) micropyle

### Step-by-Step Solution:

1. **Understanding Seed Structure**:
- Seeds are formed from ovules after fertilization. The ovule consists of several parts, including the integuments (outer and inner), nucellus, and micropyle.

2. **Identifying the Parts**:
- **Outer Integument**: This is the outer layer of the ovule and is typically present in seeds.
- **Inner Integument**: This is the inner layer of the ovule and is also usually retained in seeds.
- **Nucellus**: This is the tissue that nourishes the developing embryo and is often consumed during seed development.
- **Micropyle**: This is the small opening in the ovule that allows the pollen tube to enter and is generally retained in seeds.

3. **Analyzing the Options**:
- Options (a), (b), and (d) (outer integument, inner integument, and micropyle) are typically present in seeds.
- The **nucellus** is often not retained in most seeds after development, as it is used up during the formation of the seed.

4. **Conclusion**:
- Therefore, the part that does not have any remnant in most seeds is the **nucellus**.

### Final Answer:
(c) nucellus
