Pectic polysaccharides are present in

Options

A. Cytoskeleton
B. Plasma membrane
C. Primary cell wall
D. Teritary cell wall

Answer

**Step-by-Step Solution:**

1. **Understanding Pectic Polysaccharides**: Pectic polysaccharides are complex carbohydrates primarily found in the cell walls of plants. They play a crucial role in the structure and function of plant cells.

2. **Identifying Cell Wall Components**: The plant cell wall is made up of various components. The primary cell wall, which is formed in young plant cells, contains cellulose, hemicellulose, and pectins (which include pectic polysaccharides).

3. **Differentiating Between Cell Wall Types**: There are two main types of cell walls in plants:
- **Primary Wall**: This is the first wall formed in a young plant cell and contains pectic polysaccharides.
- **Secondary Wall**: This wall is formed later, inside the primary wall, and is made up of substances like lignin, suberin, or cutin.

4. **Evaluating the Options**: The question asks where pectic polysaccharides are present. Given that they are a component of the primary cell wall, we can conclude that they are not found in the cytoskeleton, plasma membrane, or tertiary wall.

5. **Selecting the Correct Answer**: Based on the information provided, the correct answer is that pectic polysaccharides are present in the primary cell wall of plants.

**Final Answer**: Pectic polysaccharides are present in the primary cell wall of plants.
