If in a cell suction pressure value is 30 atm, while osmotic pressure is 42 atm, then calculate the turgidity developed in form of TP in the cell :

Options

A. 12 atm.
B. 72 atm.
C. -12 atm.
D. 1.4 atm.

Answer

To calculate the turgor pressure (TP) in the cell, we will use the formula:

\[ TP = OP - SP \]

Where:
- TP = Turgor Pressure
- OP = Osmotic Pressure
- SP = Suction Pressure

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Osmotic Pressure (OP) = 42 atm
- Suction Pressure (SP) = 30 atm

2. **Apply the Formula:**
- Substitute the given values into the formula:
\[ TP = OP - SP \]
\[ TP = 42 \, \text{atm} - 30 \, \text{atm} \]

3. **Perform the Calculation:**
- Calculate the difference:
\[ TP = 12 \, \text{atm} \]

4. **Conclusion:**
- The turgor pressure (TP) developed in the cell is 12 atm.

### Final Answer:
The turgidity developed in the form of turgor pressure (TP) in the cell is **12 atm**.
