State true or False
Cathode is negative terminal both in electrochemical and electrolytic cells.

Explanation

To determine whether the statement "Cathode is negative terminal both in electrochemical and electrolytic cells" is true or false, we need to understand the characteristics of both types of cells.

### Step-by-Step Solution:

1. **Define Electrochemical Cells**:
- Electrochemical cells, such as galvanic cells, convert chemical energy into electrical energy.

2. **Identify the Cathode in Electrochemical Cells**:
- In electrochemical cells, the cathode is where reduction occurs. This terminal is positively charged because it attracts cations from the solution.

3. **Define Electrolytic Cells**:
- Electrolytic cells, on the other hand, use electrical energy to drive a non-spontaneous chemical reaction.

4. **Identify the Cathode in Electrolytic Cells**:
- In electrolytic cells, the cathode is where reduction also occurs, but this terminal is negatively charged because it is connected to the negative terminal of the power supply, attracting cations from the electrolyte.

5. **Compare the Cathodes**:
- From the definitions, we see that the cathode in an electrochemical cell is positive, while the cathode in an electrolytic cell is negative.

6. **Conclusion**:
- Since the statement claims that the cathode is negative in both types of cells, and we have established that this is not the case, the statement is false.

### Final Answer:
**False**
