Read the following statements carefully -
(A) The lipid component of the plasma membrane mainly consists of phosphoglycerides.
(B) Polar molecules can pass through the lipid bilayer of the plasma membrane, therefore they do not require carrier proteins to facilitate their transport.
(C ) The secondary wall is capable of growth and it is formed on the outer side of the primary wall.
(D) Quasifluid nature of lipid enables the lateral movement of proteins within the overall lipid bilayer of the plasma membrane.
(E) Middle lamella glues the different neighbouring cells together.
How many statements are incorrect?

Options

A. Three
B. Five
C. Four
D. Two

Answer

To solve the question, we need to evaluate each statement provided and determine whether it is correct or incorrect. Let's analyze each statement step by step.

### Step-by-Step Solution:

1. **Statement (A)**: "The lipid component of the plasma membrane mainly consists of phosphoglycerides."
- **Evaluation**: This statement is correct. The primary lipid components of the plasma membrane are indeed phosphoglycerides, which include phospholipids that form the bilayer structure.

2. **Statement (B)**: "Polar molecules can pass through the lipid bilayer of the plasma membrane, therefore they do not require carrier proteins to facilitate their transport."
- **Evaluation**: This statement is incorrect. Polar molecules cannot easily pass through the hydrophobic lipid bilayer of the plasma membrane and typically require carrier proteins or channels to facilitate their transport.

3. **Statement (C)**: "The secondary wall is capable of growth and it is formed on the outer side of the primary wall."
- **Evaluation**: This statement is incorrect. The primary cell wall is capable of growth and is formed first, while the secondary wall is formed on the inner side of the primary wall and does not grow.

4. **Statement (D)**: "Quasifluid nature of lipid enables the lateral movement of proteins within the overall lipid bilayer of the plasma membrane."
- **Evaluation**: This statement is correct. The quasi-fluid nature of the lipid bilayer allows for the lateral movement of proteins and lipids within the membrane.

5. **Statement (E)**: "Middle lamella glues the different neighboring cells together."
- **Evaluation**: This statement is correct. The middle lamella is a pectin-rich layer that serves to adhere adjacent plant cells together.

### Summary of Evaluations:
- **Correct Statements**: A, D, E
- **Incorrect Statements**: B, C

### Conclusion:
Out of the five statements, two statements (B and C) are incorrect.

### Final Answer:
**There are 2 incorrect statements.**
