Most abundant component of cell is

Options

A. Protein
B. Water
C. Cellulose
D. Lipid.

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the most abundant component of a cell.

2. **Consider the Components of a Cell**: Cells are made up of various components, including water, proteins, lipids, carbohydrates, and nucleic acids.

3. **Evaluate the Role of Water**: Water is a major component of cells, constituting about 70% of the cell's mass. It is found both inside the cell (cytosol) and outside the cell (extracellular fluid).

4. **Assess Other Components**:
- **Proteins**: While proteins are essential for many cellular functions, they do not make up the majority of the cell's mass.
- **Lipids**: Lipids are abundant in cell membranes but are not the most abundant component throughout the entire cell.
- **Cellulose**: This is primarily found in the cell walls of plant cells and is not present in all cell types.

5. **Conclusion**: Given that water constitutes a significant portion of the cell's composition, it is clear that the most abundant component of a cell is water.

6. **Final Answer**: The most abundant component of a cell is water.
