Which of the following statements about a seed produced by apomixis is incorrect?

Options

A. The seed coat is made up of diploid cells, derived from ovule of a flower
B. The embryo consists of diploid cells derived from fertilization of a haploid egg by a haploid sperm
C. A diploid embryo is present within the seed
D. The apomictic embryos can be regarded as clones

Answer

To determine which statement about a seed produced by apomixis is incorrect, we can analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Apomixis**:
- Apomixis is a form of asexual reproduction that occurs in some flowering plants, where seeds are produced without fertilization. This means that the seed develops directly from the ovule without the fusion of male and female gametes.

2. **Analyzing Each Statement**:
- **Option A**: "The seed coat is made up of diploid cells derived from the ovule of a flower."
- **Analysis**: This statement is correct. The seed coat is indeed derived from the ovule, which is diploid in nature.

- **Option B**: "The embryo consists of diploid cells derived from fertilization of haploid egg by a haploid sperm."
- **Analysis**: This statement is incorrect. In apomixis, there is no fertilization involved. The embryo develops directly from the diploid megaspore mother cell without the need for male gametes (sperm).

- **Option C**: "A diploid embryo is present within the seed."
- **Analysis**: This statement is correct. The embryo formed in apomixis is diploid since it originates from the diploid megaspore mother cell.

- **Option D**: "The apomictic embryos can be regarded as clones."
- **Analysis**: This statement is also correct. Since the embryo develops from the mother’s diploid cell without fertilization, the offspring are genetically identical to the parent, making them clones.

3. **Conclusion**:
- The only incorrect statement among the options provided is **Option B**.

### Final Answer:
- The incorrect statement about a seed produced by apomixis is **Option B**: "The embryo consists of diploid cells derived from fertilization of haploid egg by a haploid sperm."
