The most important factor for absorption of water in plants is

Options

A. living cell
B. force of capillarity
C. imbibition
D. cohesive force of water

Answer

**Step-by-Step Solution:**

1. **Understanding Water Absorption in Plants:**
- Water absorption in plants primarily occurs through the roots. The root cells are specialized for this function.

2. **Role of Living Cells:**
- Living cells in the root system have numerous pores that facilitate the absorption of water. These cells are essential for the uptake of water and nutrients.

3. **Capillarity:**
- Capillarity refers to the ability of water to move through small spaces. While it aids in the upward movement of water, it is not the most crucial factor for initial absorption.

4. **Imbibation:**
- Imbibation is the process where cells swell due to the absorption of water. It is important for the initial uptake of water but is not the primary factor.

5. **Cohesive Forces of Water:**
- Cohesion refers to the attraction between water molecules. This property helps in the movement of water within the plant but is not directly responsible for absorption.

6. **Transpiration Pull:**
- Transpiration creates a negative pressure that pulls water upward through the plant. While significant for water movement, it is not the primary factor for absorption.

7. **Conclusion:**
- The most important factor for the absorption of water in plants is the presence of living cells in the root system, which have the ability to absorb water effectively.

**Final Answer:**
The most important factor for absorption of water in plants is the presence of living cells.
