Most diverse macromolecules, found in the cell both physically and chemically are

Options

A. proteins
B. carbohydrates
C. nucleic acids
D. lipids

Explanation

### Step-by-Step Solution:

1. **Understanding Macromolecules**:
- Macromolecules are large molecules that are essential for life. They are classified based on their solubility into macromolecules and micromolecules.
- Micromolecules are small, soluble molecules, while macromolecules are larger and typically insoluble in acids.

2. **Identifying Micromolecules**:
- Examples of micromolecules include sugars, amino acids, and nucleotides. These are soluble in acids and are smaller in size.

3. **Identifying Macromolecules**:
- Examples of macromolecules include proteins, carbohydrates, nucleic acids, and lipids. These are generally insoluble in acids and larger in size.

4. **Analyzing the Composition of Macromolecules in Cells**:
- In cells, the approximate percentage composition of these macromolecules is:
- Proteins: 10-15%
- Carbohydrates: 3%
- Lipids: 2%
- Nucleic Acids: 5-10%

5. **Determining the Most Diverse Macromolecule**:
- Among the macromolecules listed, proteins have the highest percentage composition (10-15%) in cells. This indicates that proteins are the most diverse macromolecules found in cells both physically and chemically.

6. **Conclusion**:
- Therefore, the answer to the question is that the most diverse macromolecules found in cells, both physically and chemically, are **Proteins**.
