  • Question 1
    1 / -0
    Phloem tissues in plants are responsible for ___________________
    Solution

    Phloem transports the food materials, and usually from leaves to other parts of the plant. Phloem is a vascular tissue in land plants primarily responsible for the distribution of food synthesized by the leaves. It is fully developed in gymnosperm and angiosperm.

    So, the correct answer is option B. 

  • Question 2
    1 / -0
    Osmotic pressure of a solution is
  • Question 3
    1 / -0
    Water potential is maximum in case ___________.
  • Question 4
    1 / -0
    In higher plants, transport of food material occurs through ______________.
    Solution

    The food manufactured in the leaves is translocated upwards and downwards. And to all the parts of the plant through its phloem. The phloem conducts some other substances like amino acids. The conducting cells of the phloem are cylindrical cells known as sieve tubes. These partitions are known as sieve plates. Sieve elements are the food conducting cells of many phloem tissues. Sieve elements in angiosperms are the sieve tubes, while in gymnosperms and pteridophytes, these are sieve cells.

    So, the correct answer is option B.

  • Question 5
    1 / -0
    The type of water movement in the plants where protoplasm is involved is called
  • Question 6
    1 / -0
    In plants, phloem tissues perform the function of 
    Solution
    In plants, phloem tissues perform the function of  conduction of food.
    Phloem helps in conducting food materials. It is composed of:
    • Sieve tube elements
    • Companion cells
    • Phloem parenchyma
    • Phloem fibres
    Sieve tube elements are tube-like elongated structures associated with companion cells. The end walls of sieve tube elements are perforated to form the sieve plate. Sieve tube elements are living cells containing cytoplasm and nucleus. Companion cells are parenchymatous in nature. They help in maintaining the pressure gradient in the sieve tube elements. Phloem parenchyma helps in the storage of food and is made up of long tapering cells, with a dense cytoplasm. Phloem fibres are made up of elongated sclerenchymatous cells with thick cell walls.
  • Question 7
    1 / -0
    Amount by which water potential is reduced due to presence of solute is called ______________.
  • Question 8
    1 / -0
    Which apparatus is used in the measurement of root pressure ______________.
  • Question 9
    1 / -0
    Plasmolysis in a plant cell is
    Solution
    Plasmolysis is a process in which cytoplasm of the cell loses the water, shrinks and cell membrane detaches from its cell wall when kept in hypertonic solution. This occurs due to exosmosis. 
    So, the correct answer is option C.
  • Question 10
    1 / -0
    Which of the following processes keeps plant cool?
    Solution
    Transpiration keeps plant cool.
    Cooling effect:
    The leaves absorb the radiant energy. Some of the light energy is utilised in photosynthesis, rest is converted into heat energy resulting in an increase in leaf temperature. However, rapid loss of water in the form of water vapour from the aerial parts of the plant through transpiration brings down their temperature. Transpiration thus provides a significant cooling effect which keeps the plant from being over heated.
