Inorganic compound present in the cell wall of Algae is

Options

A. calcium pectate calcium chloride
B. calcium chloride
C. calcium sulphonate
D. calcium carbonate

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the inorganic compound that is present in the cell wall of algae.

2. **Analyzing the Options**: We have four options to consider:
- Option 1: Calcium Pactate
- Option 2: Calcium Chloride
- Option 3: Calcium Sulfonate
- Option 4: Calcium Carbonate

3. **Evaluating Each Option**:
- **Option 1: Calcium Pactate**: This compound is not typically found in the cell wall of algae; it is more associated with the middle lamella of plant cells.
- **Option 2: Calcium Chloride**: This compound is used in treatments that modify cell walls but is not a structural component of the cell wall itself.
- **Option 3: Calcium Sulfonate**: This compound is not known to be a component of algal cell walls.
- **Option 4: Calcium Carbonate**: This is a well-known inorganic compound that is present in the cell walls of certain algae, particularly in calcareous algae.

4. **Conclusion**: After evaluating all options, the correct answer is **Calcium Carbonate**, which is the inorganic compound present in the cell wall of algae.

**Final Answer**: The inorganic compound present in the cell wall of algae is **Calcium Carbonate**.
