Biology Question on Transport in Plants
When water moves through a semi permeable membrane then which of the following pressure develops?
A
osmotic pressure
B
suction pressure
C
turgor pressure
D
wall pressure.
Answer
osmotic pressure
Explanation
Solution
The pressure required to stop the flow of pure water into a solution across a semi permeable membrane is a characteristic of the solution, and is called the osmotic pressure. Thus water will move from a region oflow osmotic pressure to a region of high osmotic pressure. Turgor pressure is the hydrostatic pressure set up within a cell by the water present acting against the elasticity of the wall. Suction pressure when referred to a cell, is the force which is available for taking in water.
