    Which of the following is not role of boron -

  • Question 2/10
    4 / -1

    Which of the following is not chemoautotroph-

    Solutions

    all bacteria involve in nitrification are chemoautotroph and thiobaccilus are involve in denitrification

     

  • Question 3/10
    4 / -1

    Amination of which amino acid give amide –

    Solutions

    Aspargine and glutamine are already amide and OAA amination give amino acid

     

  • Question 4/10
    4 / -1

    Mark the correct statement –

    Solutions

    Leghaemoglobin synthesis require both plant and  bacteria , bacteria establish connection with both xylem and phloem and association of rhizobium and leguminous plants are non-obligatroy 

     

  • Question 5/10
    4 / -1

    Directions For Questions

    Consider the following statement A to E –

    (A) Water potential values can be positive, negative and zero

    (B) In an open beaker water potential is equal to solute potential

    (C) Addition of solute decrease solute potential

    (D) Maximum value of solute potential is zero

    (E) pressure potential can not be zero

    ...view full instructions

    How many are correct-

    Solutions

    Explanation- In open beaker pressure potential is zero and value of water potential is equal to solute potential and if no solute is present in beaker than value of solute potential is maximum which is equal to zero

     

  • Question 6/10
    4 / -1

    Diffusion of any molecule across membrane depend upon on all except-

    Solutions

    Diffusion is passive not require energy

     

  • Question 7/10
    4 / -1

    Directions For Questions

    Consider the following –

    (A)turgor pressure

    (B) osmotic pressure

    (C) root pressure

    (D) transpiration pull

    (E) Osmotic potential

    (F) Suction pressure

    ...view full instructions

    How many are positive pressure-

    Solutions

    osmotic potential, suction pressure and transpiration pull are negative pressure

     

  • Question 8/10
    4 / -1

    Which of the following can contribute as a force for transport of water in plant-

    Solutions

    apoplast and symplast are pathway not force for transport of water

     

  • Question 9/10
    4 / -1

    Which is correct regarding the transport in phloem-

    Solutions

    since sieve tube is living so movement is symplast and pressure is positive due to entry of water

     

  • Question 10/10
    4 / -1

    Correct Reason for root pressure –

    Solutions

    Root pressure develop in roots due to accumulation of solute in Root xylem
