The main lipid components of the plant cell membrane are :-

Options

A. Phosphodiesters
B. Glycocalyx
C. Peptidoglycan
D. Phosphoglycerides

Answer

To answer the question regarding the main lipid components of the plant cell membrane, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Composition of Plant Cell Membrane**:
- The plant cell membrane is primarily composed of a lipid bilayer, which includes various types of lipids, proteins, and carbohydrates.

2. **Identify the Main Lipid Components**:
- The main lipid components of the plant cell membrane are phospholipids. These phospholipids are specifically known as phosphoglycerides.

3. **Differentiate Between Other Options**:
- It is important to distinguish phospholipids from other components mentioned in the question:
- **Phosphodiester**: This refers to a type of bond found in nucleic acids, not a lipid component.
- **Glycocalyx**: This is a carbohydrate-rich layer found in some cells, particularly bacteria, and is not a lipid.
- **Peptidoglycan**: This is a structural component of bacterial cell walls and is not found in plant cell membranes.

4. **Conclude with the Correct Answer**:
- Based on the above analysis, the main lipid components of the plant cell membrane are phosphoglycerides. Therefore, the correct answer is option number 4.

### Final Answer:
The main lipid components of the plant cell membrane are phosphoglycerides.
