The pressure responsible for emerge out of seedlings from the soil is

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of pressure responsible for seedlings emerging from the soil.

2. **Identifying the Process**: The key process involved in this phenomenon is called **imbibition**. Imbibition refers to the absorption of water by solid particles, which causes an increase in volume.

3. **Defining Imbibition**: Imbibition is the process where solid substances (like seeds) absorb water without forming a solution. The solid that absorbs water is referred to as the **imbibant**, while the liquid absorbed is called the **imbibate**.

4. **Mechanism of Imbibition**: When seeds absorb water through their roots, they swell due to the imbibition process. This swelling generates pressure within the seed, which helps push the seedling out of the soil.

5. **Conclusion**: Therefore, the pressure responsible for the emergence of seedlings from the soil is due to the **imbibition** process, which leads to an increase in volume and pressure within the seed.
