Absorption by Roots Welcome to your Absorption by Roots 1. The space between the cell wall and plasma membrane in a plasmolysed cell is filled with Isotonic solution Hypertonic solution Water Hypotonic solution2. Marine fish when thrown under tap water bursts because of Plasmolysis Diffusion Exosmosis Endosmosis3. Plasma membrane controls Passage of water and solutes in and out of the cell Movement of cell contents out of the cell Passage of water only Passage of water and solutes into the cell4. When a plant wilts, the sequence of events is as follows: Exosmosis, plasmolysis, temporary and permanent wilting Exosmosis, plasmolysis, deplasmolysis, temporary wilting None of the above Exosmosis, deplasmolysis, plasmolysis, temporary and permanent wilting5. Seeds when soaked in water imbibe in it because There are many vacuoles in the endosperm The process of absorption works Seed coat contains lot of salts Osmotic pressure inside the seed is low6. Water will be absorbed by the root hairs when: The plant is rapidly respiring Concentration of solutes in the cell sap is high None of the above Concentration of solutes in the soil is high7. Osmosis involves Movement of water through cortical cells Active absorption of water through roots Cell to cell movement of water All the above8. When cell is fully turgid, which of the following will be zero? Suction pressure(SP) or Diffusion pressure Deficit (DPD) Osmotic pressure Wall pressure Turgor pressure9. Osmosis involves diffusion of Suspended particles from lower to higher concentration Molecules or ions from the more concentrated solution to the less concentrated solution Solvent particles from the less concentrated solution to the more concentrated solution Suspended particles from higher to lower concentration10. In the process of Osmosis in a cell: Both protoplasm and cell wall act as a membrane Only outermost layer of protoplast acts as a membrane The entire protoplast acts as a membrane Only cell wall acts as a membrane11 out of 10Please fill in the comment box below.
