Which of the following compounds is found abundantly in nature?

Options

A. Fructose
B. Starch
C. Glucose
D. Cellulose

Explanation

To determine which of the following compounds is found abundantly in nature, we will analyze each option provided: fructose, starch, glucose, and cellulose.

### Step-by-Step Solution:

1. **Understanding the Compounds**:
- **Fructose**: A simple sugar (monosaccharide) found in many plants, but not the most abundant compound in nature.
- **Starch**: A polysaccharide made up of glucose units, primarily used by plants for energy storage. It is abundant but not as much as cellulose.
- **Glucose**: Another simple sugar (monosaccharide) that is a primary energy source for living organisms but is not found in large quantities in nature as a free molecule.
- **Cellulose**: A polysaccharide that is a major component of plant cell walls. It is composed of long chains of glucose units linked together.

2. **Analyzing Abundance in Nature**:
- Among these compounds, cellulose is the most abundant organic polymer on Earth. It constitutes a significant part of the biomass of plants, making it the primary structural component of their cell walls.

3. **Conclusion**:
- Based on the analysis, the compound that is found abundantly in nature is **cellulose**.

### Final Answer:
The compound that is found abundantly in nature is **cellulose**.
