From given statements with reference to the embryo, which of these are incorrect?
a. A typical dicot embryo consists of an embryonal axis and 2 cotyledons.
b. The portion of the embryonal axis above the level of cotyledons is hypocotyl.
c. The protein below the level of cotyledons is epicotyl.
d. The epicotyl terminates with the stem tip, and the hypocotyl terminates with the root tip.

Options

A. a and c
B. b and c
C. a and d
D. c and d

Answer

To determine which statements about the embryo are incorrect, we will analyze each statement one by one.

### Step 1: Analyze Statement A
**Statement A**: A typical dicot embryo consists of an embryonal axis and 2 cotyledons.
- **Analysis**: This statement is correct. Dicot embryos typically have two cotyledons.

### Step 2: Analyze Statement B
**Statement B**: The portion of the embryonal axis above the level of cotyledons is hypocotyl.
- **Analysis**: This statement is incorrect. The portion of the embryonal axis above the level of cotyledons is called the **epicotyl**, while the hypocotyl is the part below the cotyledons.

### Step 3: Analyze Statement C
**Statement C**: The portion below the level of cotyledons is epicotyl.
- **Analysis**: This statement is also incorrect. The portion below the level of cotyledons is called the **hypocotyl**, not the epicotyl.

### Step 4: Analyze Statement D
**Statement D**: The epicotyl terminates with the stem tip, and the hypocotyl terminates with the root tip.
- **Analysis**: This statement is correct. The epicotyl does indeed terminate with the stem tip, and the hypocotyl terminates with the root tip.

### Conclusion
The incorrect statements are **B** and **C**.

### Final Answer
The incorrect statements are:
- B. The portion of the embryonal axis above the level of cotyledons is hypocotyl.
- C. The portion below the level of cotyledons is epicotyl.
