Hydrophilic chemical of cell wall is

Options

A. Pectin
B. Suberin
C. Fat
D. Lignin

Answer

To answer the question about the hydrophilic chemical of the cell wall, we can follow these steps:

### Step 1: Understand the Question
The question asks for a hydrophilic (water-loving) chemical component found in the cell wall.

### Step 2: Define Hydrophilic
Hydrophilic substances are those that can interact with water, often due to the presence of polar groups or charged groups that can form hydrogen bonds with water molecules.

### Step 3: Analyze the Options
- **A. Pactin**: This is a polysaccharide that is known to be hydrophilic.
- **B. Subranium**: This is not a commonly recognized term in biology and does not refer to a known component of the cell wall.
- **C. Fat**: Fats are typically hydrophobic (water-repelling) and do not mix well with water.
- **D. Lignin**: While lignin is a component of the cell wall, it is also considered hydrophobic.

### Step 4: Identify the Correct Answer
Among the options provided, **Pactin** is the only hydrophilic chemical present in the cell wall. It is a polysaccharide that interacts well with water, making it the correct answer.

### Final Answer
The hydrophilic chemical of the cell wall is **A. Pactin**.
