Question

which of these could turgor pressure best be compared to?
water pushing a turbine at a hydroelectric plant
different amounts of water filling a water balloon
blood moving through the circulatory system
a frozen icicle standing straight upright

Explanation:

Turgor pressure is the pressure exerted by water within the cell, which is similar to the pressure of water filling a water balloon. In a water balloon, as more water is filled (analogous to water entering a plant cell by osmosis), the balloon (cell) gets pressurized. A frozen icicle is a solid - ice structure with no internal fluid pressure like turgor. Blood moving through the circulatory system has blood pressure which is a different physiological pressure mechanism. Water pushing a turbine at a hydroelectric plant is a form of fluid - dynamic pressure for energy generation, not the same as the internal cell - based turgor pressure.

Answer:

Different amounts of water filling a water balloon.
