Polysaccharide that acts as store house of energy in plant tissue is_____

Answer

To answer the question about the polysaccharide that acts as a storehouse of energy in plant tissue, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a polysaccharide that serves as an energy reserve in plants. We need to identify which polysaccharide fulfills this role.

2. **Identifying Polysaccharides**: Polysaccharides are large molecules made up of many sugar units. Common examples include starch, glycogen, and cellulose.

3. **Function of Polysaccharides in Plants**: In plants, polysaccharides primarily serve two functions: structural support (like cellulose) and energy storage (like starch).

4. **Focusing on Energy Storage**: Since the question specifically asks for an energy storehouse, we can eliminate cellulose, which is primarily for structure.

5. **Identifying the Correct Polysaccharide**: The primary polysaccharide used by plants for energy storage is starch. Starch is composed of two components: amylose and amylopectin.

6. **Composition of Starch**: Starch consists of approximately 75-80% amylopectin and 20-25% amylose. This composition allows starch to effectively store energy in a compact form.

7. **Conclusion**: Based on the above analysis, the polysaccharide that acts as a storehouse of energy in plant tissue is **starch**.

### Final Answer:
The polysaccharide that acts as a storehouse of energy in plant tissue is **starch**.
