Select the incorrect statement w.r.t eukaryotic cell

Options

A. Membrane bound organelles are present
B. Sap vacuoles are commonly found in plant cells
C. Contains 80 S ribosomes
D. Plasma membrane is symmetrical in nature

Answer

To solve the question of selecting the incorrect statement with respect to eukaryotic cells, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "Membrane-bound organelles are present."
- **Analysis**: This statement is true. Eukaryotic cells are characterized by the presence of membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, etc.

2. **Statement 2**: "SAP vacuoles are commonly found in plant cells."
- **Analysis**: This statement is also true. SAP vacuoles, or simply vacuoles, are large central vacuoles typically found in plant cells, serving various functions including storage and maintaining turgor pressure.

3. **Statement 3**: "Contains 80S ribosomes."
- **Analysis**: This statement is true. Eukaryotic cells contain 80S ribosomes, which are composed of a 60S large subunit and a 40S small subunit.

4. **Statement 4**: "Plasma membrane is symmetrical in nature."
- **Analysis**: This statement is incorrect. The plasma membrane of eukaryotic cells is asymmetrical due to the presence of various proteins and lipids that are distributed unevenly across the membrane layers.

### Conclusion:
The incorrect statement regarding eukaryotic cells is: **"Plasma membrane is symmetrical in nature."**
