The right sequence for imbibition is

Options

A. Agar agar > cellulose > protein
B. Protein > cellulose > agar agar
C. Agar agar > protein > cellulose
D. cellulose > Agar agar > protein

Answer

### Step-by-Step Solution:

1. **Understanding Imbibition**: Imbibition is the process by which solid particles absorb water without forming a solution. This is a crucial process in plants, especially during seed germination.

2. **Identifying Imbibients**: The effectiveness of different materials as imbibients varies. The materials discussed include agar-agar, protein, and cellulose.

3. **Ranking Imbibients**:
- **Agar-Agar**: It is identified as the most powerful imbibient, capable of absorbing up to 99% of its weight in water.
- **Protein**: The next in line, it can absorb about 15% of its weight in water.
- **Cellulose**: This is the weakest imbibient among the three, absorbing the least amount of water.

4. **Establishing the Sequence**: Based on the absorption capacities:
- First: Agar-Agar (most powerful)
- Second: Protein
- Third: Cellulose (weakest)

5. **Final Sequence**: Therefore, the correct sequence for imbibition is:
- Agar-Agar → Protein → Cellulose
