Phospholipid molecules of cell membrane posses

Options

A. One polar head and one polar tail
B. One non-polar head nad one non-polar tail
C. One polar head and two nonpolar tails
D. One nonpolar head and two polar tails .

Answer

### Step-by-Step Solution:

1. **Understanding Phospholipid Structure**:
Phospholipids are the primary components of cell membranes. They consist of a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails.

2. **Identifying the Components**:
- The **head** of the phospholipid is polar (hydrophilic), which means it can interact with water.
- The **tails** are non-polar (hydrophobic), which means they do not interact with water.

3. **Counting the Components**:
Each phospholipid molecule has:
- **One polar head**
- **Two non-polar tails**

4. **Evaluating the Options**:
The question provides four options regarding the structure of phospholipids:
- One polar head and one polar tail (Incorrect)
- One non-polar head and one non-polar tail (Incorrect)
- One polar head and two non-polar tails (Correct)
- One non-polar head and two polar tails (Incorrect)

5. **Conclusion**:
The correct answer is that phospholipid molecules of the cell membrane possess **one polar head and two non-polar tails**.
