Cells absorb water through

Options

A. Osmosis olny
B. Imbibition only
C. Both osmosis and imbibition
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Osmosis**:
- Osmosis is defined as the movement of water molecules through a semi-permeable membrane from a region of higher water concentration to a region of lower water concentration. This process is crucial for cells as it helps maintain their turgor pressure and overall hydration.

2. **Understanding Imbibation**:
- Imbibation is another process of water absorption, but it does not require a semi-permeable membrane. It typically occurs in seeds and other plant tissues. When seeds are placed in water, they absorb it and swell due to imbibation. This process is a type of diffusion where water moves into the seed, causing it to expand.

3. **Conclusion**:
- Both osmosis and imbibation are processes through which cells can absorb water. Osmosis is specifically related to the movement of water across a semi-permeable membrane, while imbibation refers to the absorption of water by solid materials, such as seeds, without the need for a membrane.

4. **Final Answer**:
- Cells absorb water through both osmosis and imbibation.
