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

Answer

To solve the question of selecting an incorrect statement for cereal seeds, we will analyze each statement provided and determine its validity.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "Seed coat is membranous."
- **Evaluation:** This statement is true. The seed coat of cereal seeds is indeed membranous and is also fused with the fruit wall.

2. **Analyze the Second Statement:**
- **Statement:** "Endosperm is bulky and stores food."
- **Evaluation:** This statement is also true. The endosperm in cereal seeds is bulky and serves the purpose of food storage.

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

4. **Analyze the Fourth Statement:**
- **Statement:** "The outer covering of the endosperm separates the embryo by a proteinaceous layer called the aleurone layer."
- **Evaluation:** This statement is true. The outer covering of the endosperm does separate the embryo from the endosperm by a proteinaceous layer known as the aleurone layer.

### Conclusion:
Based on the evaluations, the incorrect statement regarding cereal seeds is the third statement: "The embryo is large and situated in a groove at one end of the endosperm."

### Final Answer:
The incorrect statement is: **"The embryo is large and situated in a groove at one end of the endosperm."**
