D. The outer covering of endosperm separates the embryo by a proteinous layer called aleurone layer

Answer

### Step-by-Step Solution:

1. **Understanding Cereal Seeds**: Cereal seeds, such as maize, have specific structures that include the seed coat, endosperm, and embryo.

2. **Analyzing the Statements**:
- **Statement 1**: "Seed coat is membranous."
- This is correct. The seed coat of cereal seeds is indeed membranous and often fused with the fruit wall.

- **Statement 2**: "Endosperm is bulky and stores food."
- This is also correct. The endosperm in cereal seeds is bulky and serves as a food reserve for the developing embryo.

- **Statement 3**: "The embryo is very large and situated in a groove at one end of the endosperm."
- This statement is incorrect. In cereal seeds, the embryo is actually small and located at one end of the endosperm, not large and situated in a groove.

- **Statement 4**: "The outer covering of endosperm separates the embryo by a proteinaceous layer called the Aleuron layer."
- This statement is correct. The Aleuron layer is a proteinaceous layer that separates the embryo from the endosperm.

3. **Identifying the Incorrect Statement**: Based on the analysis, the incorrect statement is the one that claims the embryo is very large and situated in a groove at one end of the endosperm.

4. **Conclusion**: Therefore, the answer to the question "Select an incorrect statement for cereal seeds" is that the statement regarding the embryo being very large is incorrect.
