Water entering the root due to diffusion is part of

Options

A. endosmosis
B. osmosis
C. passive absorption
D. active absorption

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Process of Water Absorption in Roots:**
- The roots of plants are responsible for absorbing water from the soil. This process is crucial for the plant's survival and growth.

2. **Identifying the Mechanism of Water Entry:**
- The question specifies that water enters the root due to diffusion. Diffusion is a passive process where molecules move from an area of higher concentration to an area of lower concentration.

3. **Defining Passive Absorption:**
- Since diffusion does not require energy input from the plant (it occurs naturally due to concentration gradients), the absorption of water through this method is termed "passive absorption."

4. **Differentiating from Other Processes:**
- It is important to note that passive absorption is different from active absorption, which requires energy. Other processes like osmosis and endosmosis involve specific mechanisms that are not applicable in this case.

5. **Conclusion:**
- Therefore, the correct answer to the question is that water entering the root due to diffusion is part of **passive absorption**.
