Absorption by Roots Welcome to your Absorption by Roots 1. In the process of Osmosis in a cell: Both protoplasm and cell wall act as a membrane Only cell wall acts as a membrane The entire protoplast acts as a membrane Only outermost layer of protoplast acts as a membrane2. When a plant wilts, the sequence of events is as follows: Exosmosis, plasmolysis, temporary and permanent wilting Exosmosis, deplasmolysis, plasmolysis, temporary and permanent wilting Exosmosis, plasmolysis, deplasmolysis, temporary wilting None of the above3. Marine fish when thrown under tap water bursts because of Endosmosis Exosmosis Plasmolysis Diffusion4. Osmosis involves Active absorption of water through roots Movement of water through cortical cells All the above Cell to cell movement of water5. The space between the cell wall and plasma membrane in a plasmolysed cell is filled with Hypertonic solution Water Hypotonic solution Isotonic solution6. Water will be absorbed by the root hairs when: Concentration of solutes in the soil is high None of the above Concentration of solutes in the cell sap is high The plant is rapidly respiring7. Osmosis involves diffusion of Solvent particles from the less concentrated solution to the more concentrated solution Suspended particles from lower to higher concentration Suspended particles from higher to lower concentration Molecules or ions from the more concentrated solution to the less concentrated solution8. Seeds when soaked in water imbibe in it because There are many vacuoles in the endosperm The process of absorption works Osmotic pressure inside the seed is low Seed coat contains lot of salts9. Plasma membrane controls Passage of water and solutes in and out of the cell Passage of water only Passage of water and solutes into the cell Movement of cell contents out of the cell10. When cell is fully turgid, which of the following will be zero? Suction pressure(SP) or Diffusion pressure Deficit (DPD) Wall pressure Turgor pressure Osmotic pressure11 out of 10Please fill in the comment box below.
