When sugars are actively transported into a cell, what happens to T.P. inside that cell as a result -

Options

A. No change, sugar conc, has no effect on T.P.
B. Increases because sugar conc. directly affects T.P.
C. Decreases, because water exits and affect turgor pressure (T.P.)
D. Increases, because water enters and affects T.P.

Answer

**Step-by-Step Solution:**

1. **Understanding Active Transport of Sugars:**
- When sugars are actively transported into a plant cell, they move against their concentration gradient. This means that the concentration of sugars inside the cell increases.

2. **Effect on Solute Concentration:**
- As the concentration of sugars (a solute) increases inside the cell, it affects the overall solute concentration. The presence of more solute (sugar) leads to a decrease in the water potential of the cell.

3. **Osmotic Pressure and Water Movement:**
- With a higher concentration of solutes (sugars), the osmotic pressure inside the cell increases. However, the water potential decreases, which causes water to move out of the cell to balance the solute concentration. This process is known as exoosmosis.

4. **Impact on Turgor Pressure (TP):**
- Turgor pressure (TP) is the pressure exerted by the fluid (water) inside the cell against the cell wall. As water exits the cell, the volume of water inside the cell decreases, leading to a decrease in turgor pressure.

5. **Conclusion:**
- Therefore, when sugars are actively transported into a cell, the turgor pressure (TP) inside that cell decreases because water is leaving the cell.

**Final Answer:**
- The turgor pressure (TP) decreases because water exits the cell and affects the pressure.
