  • Question 1
    1 / -0
    Loss of water in the form of water vapour from plants to atmosphere is called as
    Solution
    Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. 
    Therefore, the correct answer is option C.
  • Question 2
    1 / -0
    Transport of food from leaves to other parts of the plant is called _________.
  • Question 3
    1 / -0
    The loss of the water from leaves of plants is called as
    Solution
    Transpiration is the process by which moisture or water is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transfusion and translocation do not involve the loss of water. 
    Therefore, the correct answer is option B.
  • Question 4
    1 / -0
    The process of plasmolysis in plant cell may be defined as
    Solution
    Plasmolysis can be defined as the shrinkage of the cytoplasm of a plant cell, away from its cell wall and toward the center. It occurs because of the movement of water from the intracellular space to the outer cellular space. This happens when the plant cell is placed in a hypertonic solution (i.e., a solution having more solute concentration than the cell cytoplasm). This causes the water to move out of the cell and toward the solution. The cytoplasm of the cell shrinks and the cell is said to be plasmolysed. This process can be observed in an onion peel kept in a highly concentrated salt solution.
    So, the correct answer is option B.
  • Question 5
    1 / -0
    The process of loss of water through the leaves and stem is called 
    Solution
    Transpiration is defined as the evaporation of water from plants. It occurs in the leaves through the stomata. It depends on temperature, humidity, availability of soil moisture and the type of plant. Thus the correct answer is option A.
  • Question 6
    1 / -0
    The process in which cells lose water in a hypertonic solution is called as 
    Solution
    Plasmolysis is the situation in which cells lose water in a hypertonic solution. If a plant cell is placed in a hypertonic solution, the plant cell loses water and hence, cell shrinks or contracts and making the protoplasm of the cell away from the cell wall. 
  • Question 7
    1 / -0
    Pressure caused by water entering the root from soil is known as
    Solution
    Root pressure can be defined as the pressure exerted by the cortical cells of the root upon the sap in the xylem vessels which pushes the sap upward if the stem of the plant is cut just above the root water seeps or exudes out of the cut end of the stem for a considerable period of time. This indicates that there is a force pushing water up the stem from the roots.
  • Question 8
    1 / -0
    The phenomenon by which a substance absorbs a liquid and swells, but does not necessarily dissolve in the liquid is known as
    Solution
    Imbibition is a special type of diffusion when water is absorbed by solids- colloids causing an enormous increase in volume. Examples include the absorption of water by seeds and dry wood.
  • Question 9
    1 / -0
    Root pressure is a _______
    Solution
    Root pressure provides a force which causes pushing of water in a stem. A continuous flow of water is maintained in the plants because the leaves transpire water through stomata and to replace the lost water, the water drawn by the roots moves up.
  • Question 10
    1 / -0
    Root pressure can be measured by
    Solution
    • The root pressure can be measured by attaching a suitable mercury manometer to the cut end of the stem. Root pressure provides a force that causes the pushing of water in the stem. 
    • A continuous flow of water is maintained in the plants because the leaves transpire water through stomata and to replace the lost water the water drawn by the roots moves up.
    • The barometer is used to measure atmospheric pressure.
    • The thermometer is used to measure temperature.
    • The potometer is used to measure the rate of transpiration.
    So, the correct answer is option B.
