MCQs on Absorption by Root
(Class 10 Concise ICSE Biology Selina Solutions Ch-4 Absorption by Root–The Process Involved)
Que-1: The hydrostatic pressure of the cell sap on the cell wall is called :
- Turgor pressure
- Osmotic pressure
- Wall pressure
- Atmospheric pressure
Sol: Turgor pressure
Hint: the pressure applied by the cell contents on the wall of cell is Turgor pressure
Que-2: When a cell in solution shrinks and loses its shape, then the solution is :
- Isotonic
- Potable water
- Hypotonic
- Hypertonic
Sol: Hypertonic
Hint: The concentration of solutes in hypertonic solution is more than the cell sap. so Exo osmosis occurs, Hence water moves out of the cell and it shrinks.
Que-3: The process for which energy is required is :
- Passive transport
- Diffusion
- Osmosis
- Active transport
Sol: Active transport
Hint: Active transport involves use of energy as such transport is against the gradient
Que-4: The highest water potential is that of :
- 10% sugar solution
- Honey
- 10% salt solution
- Pure water
Sol: Pure water
Hint: Water potential is define as the capacity of water to move from lower to higher concentrated solution. It is highest for pure water.
Que-5: When the cells of a plant are fully distended, the condition is called :
- Flaccidity
- Shrinkage
- Plasmolysis
- Deplasmolysis
Sol: Deplasmolysis
Hint: When plasmolysed cell is kept in a hypotonic solution, endo-Osmosis occurred therefore cell gets fully distended.
Que-6: Which of the following creates a suction force in plants ?
- Transportation
- Translocation
- Transpiration
- Transformation
Sol: Transpiration
Hint: Transpiration creates a suction force called transpiration pull. It works with root pressure due to which the roots absorb water and rose via xylem to highest part of the plant.
Que-7: The phenomenon by which living/dead plant cells absorb water by surface attraction is called :
- Inhibition
- Cohesion
- Adhesion
- Imbibition
Sol: Imbibition
Hint: Substances which are made up of cellulose or proteins are hydrophilic in nature hence absorb water and this process is called imbibition
Que-8: Which of the following is a living semi-permeable membrane ?
- Cell wall
- Cell membrane
- Cellulose
- None
Sol: Cell membrane
Hint: Cell membrane has tiny pore in it So it is semi-permeable and allows entry of limited size substances and prevent the movement of bigger substances.
Que-9: Addition of salt to pickles is a method of killing the bacteria by :
- Imbibition
- Diffusion
- Deplasmolysis
- Plasmolysis
Sol: Plasmolysis
Hint: Adding salt/sugar to the pickle increases the concentration of solute outside comparing the cells of bacteria. This results in movement of water outwards (Exo-Osmosis) from the cell and thus bacteria gets killed.
Que-10: Root pressure can be measured by using :
- Sphygmomanometer
- Barometer
- Manometer
- Thermometer
Sol: Manometer
Hint: It is device to measure root pressure. manometer liquids are mercury, water, and light oils. – One end of a U-tube manometer is connected to an unknown pressure while the other end is left exposed to the atmospheric pressure. The difference in the height of the liquid on the two sides of the tube is the differential pressure
