Absorption by Roots Welcome to your Absorption by Roots 1. Osmosis involves diffusion of Molecules or ions from the more concentrated solution to the less concentrated solution Suspended particles from lower to higher concentration Solvent particles from the less concentrated solution to the more concentrated solution Suspended particles from higher to lower concentration2. The space between the cell wall and plasma membrane in a plasmolysed cell is filled with Hypotonic solution Water Isotonic solution Hypertonic solution3. Seeds when soaked in water imbibe in it because Osmotic pressure inside the seed is low The process of absorption works There are many vacuoles in the endosperm Seed coat contains lot of salts4. Marine fish when thrown under tap water bursts because of Diffusion Endosmosis Exosmosis Plasmolysis5. Osmosis involves Cell to cell movement of water Movement of water through cortical cells Active absorption of water through roots All the above6. When a plant wilts, the sequence of events is as follows: None of the above Exosmosis, plasmolysis, temporary and permanent wilting Exosmosis, plasmolysis, deplasmolysis, temporary wilting Exosmosis, deplasmolysis, plasmolysis, temporary and permanent wilting7. Water will be absorbed by the root hairs when: The plant is rapidly respiring None of the above Concentration of solutes in the soil is high Concentration of solutes in the cell sap is high8. Plasma membrane controls Passage of water and solutes into the cell Movement of cell contents out of the cell Passage of water only Passage of water and solutes in and out of the cell9. When cell is fully turgid, which of the following will be zero? Suction pressure(SP) or Diffusion pressure Deficit (DPD) Osmotic pressure Turgor pressure Wall pressure10. In the process of Osmosis in a cell: The entire protoplast acts as a membrane Both protoplasm and cell wall act as a membrane Only outermost layer of protoplast acts as a membrane Only cell wall acts as a membrane11 out of 10Please fill in the comment box below.
