Which one of the following is the common storage product of photosynthesis

Options

A. Protein
B. Fat
C. Starch
D. Sucrose/glucose.

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. This process primarily occurs in the chloroplasts of plant cells.

2. **Raw Materials of Photosynthesis**: The main raw materials required for photosynthesis are carbon dioxide (CO2) from the air and water (H2O) from the soil. These materials are transformed into glucose (C6H12O6) through a series of reactions powered by sunlight.

3. **Formation of Glucose**: During photosynthesis, light energy is absorbed by chlorophyll, which helps in the conversion of CO2 and H2O into glucose. The overall equation for photosynthesis can be summarized as:
\[ 6CO_2 + 6H_2O + light \ energy \rightarrow C_6H_{12}O_6 + 6O_2 \]

4. **Storage of Energy**: While glucose is the immediate product of photosynthesis, it is not the long-term storage form of energy. Plants convert glucose into starch for storage. Starch is a polysaccharide made up of many glucose units linked together by glycosidic bonds.

5. **Starch as Storage Product**: Starch serves as the common storage product of photosynthesis in plants. It is stored in various parts of the plant, such as roots, stems, and leaves, and can be broken down into glucose when the plant needs energy.

6. **Conclusion**: Among the options provided (protein, fats, starch, sucrose, glucose), the common storage product of photosynthesis is starch.

**Final Answer**: Starch
