In multi-cellular organisms, cells are usually

Options

A. independent of each other
B. dependent upon each other
C. incapable of transporting substances
D. incapable of multiplication

Answer

**Step-by-Step Solution:**

1. **Understanding Multicellular Organisms**:
- Multicellular organisms are made up of more than one cell. Each cell has a specific function, and they work together to maintain the life of the organism.

2. **Analyzing the Options**:
- The question provides four options regarding the nature of cells in multicellular organisms.

3. **Evaluating the First Option**:
- The first option states that cells are "independent of each other." This is incorrect because cells in multicellular organisms interact and depend on one another for various functions.

4. **Evaluating the Second Option**:
- The second option states that cells are "dependent on each other." This is correct. Cells in multicellular organisms coordinate their activities and rely on each other for survival and function.

5. **Evaluating the Third Option**:
- The third option states that cells are "incapable of transporting substances." This is incorrect because cells can transport substances within the organism, and they often work together to facilitate this process.

6. **Evaluating the Fourth Option**:
- The fourth option states that cells are "incapable of multiplication." This is also incorrect because cells in multicellular organisms can divide and multiply to support growth and repair.

7. **Conclusion**:
- After evaluating all the options, the correct answer is that in multicellular organisms, cells are usually "dependent on each other."

**Final Answer**: Cells in multicellular organisms are usually dependent on each other.
