Another term used to indicate imbibition pressure is

Options

A. (a) matric potential
B. (b) absorption potential
C. (c) turgor potential
D. (d) chemical potential

Answer

**Step-by-Step Solution:**

1. **Understanding Imbibition**: Imbibition is a special type of diffusion where water is absorbed by solids, particularly seeds, causing them to swell. This process is crucial during seed germination.

2. **Identifying Imbibition Pressure**: Imbibition pressure is the pressure exerted by the absorbed water in the imbibate (in this case, the seeds). It is a key factor in the imbibition process.

3. **Alternative Terms for Imbibition Pressure**: Imbibition pressure is often referred to as "matric potential." Matric potential is a measure of the energy status of water in soil or plant tissues and is crucial for understanding water movement.

4. **Evaluating Options**:
- Option A: Matric potential - This is equivalent to imbibition pressure.
- Option B: Absorption potential - This is not synonymous with imbibition pressure.
- Option C: Turgor potential - This relates to cell pressure but is not the same as imbibition pressure.
- Option D: Chemical potential - This is a broader term and does not specifically refer to imbibition pressure.

5. **Conclusion**: The correct answer is Option A: Matric potential, as it is another term used to indicate imbibition pressure.
