  • Question 1
    1 / -0
    Which of the following is imbibiant?
    Solution
    Imbibition is the surface adsorption of water. Living cells are not required. All biomolecules imbibe water but to different extent. Proteins imbibe maximum water then carbohydrates and fats the least. Thus, the correct answer is option D.
  • Question 2
    1 / -0
    Wilting of plant is present in
    Solution
    Passive absorption of water under the influence of transpiration pull is responsible for ascent of sap in higher plants. The transpiration loss of water occurs through stomata in leaves of higher plants. If theres is more water loss during transpiration than can be absorbed from soil, the plant shows wilting and leaves and other aerial parts droop down. 
    Algae do not show this type of water movement as they are aquatic thallophyte plants and have well developed vascular tissue. 
    Fern and mosses are bryophytes, which also do not have well developed sporophyte distinguished into root, stem and leaves. Well developed vascular system is absent in thallophytes and bryophytes. 
    Gymnosperms are the first plant group having well developed vascular system and show ascent of sap due to transpiration from leaves. In case transpiration is more than absorption; they show wilting.
  • Question 3
    1 / -0
    Seeds swell when placed in water due to 
    Solution
    Imbibition is the adsorption of water by the solid and dry surface. It is a surface phenomenon. Imbibition is the first process to occur in seed germination. It makes seed coat moist and swelled seeds.
  • Question 4
    1 / -0
    Swelling in wooden block placed in water is due to
    Solution
    Imbibition is the adsorption of water by the solid and dry surface. Living tissues are not required for imbibition. For example, seed germination and swelling of wood on exposure to moisture. If a wooden block is placed in water it will imbibe water and swell. 
  • Question 5
    1 / -0
    If a cell is placed in a hypertonic solution then $$\Psi_{w}$$ of the cell will be
    Solution
    Water potential depends on the number of water molecules in the solution. If a cell is placed in hypertonic solution, water will flow out of the cell through the process of exosmosis. Hence, the number of water molecules will reduce. Consequently, there will be a decrease in water potential.
  • Question 6
    1 / -0
    First step of influx of water into a plant is
    Solution
    Imbibition is a physical process of adsorption of water by the solid and dry surface. It is the first process during seed germination which involves in the growth and development of plants. Thus, the correct answer is option B.
  • Question 7
    1 / -0
    Which of the following seeds develops a greater imbibition pressure?
    Solution
    Imbibition is the first process during seed germination. It is the adsorption of water by the solid and dry surface. All biomolecules imbibe water but to different extent. Proteins imbibe maximum water and fats least. Hence, protein rich gram seeds will develop maximum imbibition pressure and fat rich mustard seeds the least. This is because fats are hydrophobic. Thus, the correct answer is option B.
  • Question 8
    1 / -0
    To initiate cell plasmolysis, the soution outside the cell must be
    Solution
    Water moves from a region or solution of high water potential to a region or solution of low water potential. Thus, water always moves from a less concentrated to a more concentrated solution. If a cell is placed in a highly concentrated salt solution, water will move out from the cell into the surrounding solution, along the water potential gradient. This process is called as exosmosis and will lead to plasmolysed or shrunk protoplasm.
  • Question 9
    1 / -0
    Swelling of wooden planks and door-panels during the rainly season is due to
    Solution
    Imbibition is a physical process of adsorption of water by the solid and dry surface. During rainy season wooden furniture and frames of door and windows adsorb water due to high atmospheric humidity and misaligned. Hence, all wooden furnitures should be covered with a coat of paint to prevent imbibition during the rainy season.
  • Question 10
    1 / -0
    In osmosis there is movement of
    Solution
    Osmosis is defined as movement of solvent (water in living systems) from a region or solution of its own high concentration (less concentrated solution) to a region or solution of its own low concentration (more concentrated solution), across a semipermeable membrane.
