Study the following statements and choose the correct option$(s)$ from the codes below:
$I$. Root pressure provides a light push in the overall process of water transport.
$II$. Root pressure causes the flow of water faster through xylem than it can be lost by transpiration.
$III$. In symplast pathway,water moves exclusively through the cell wall and intercellular spaces.
$IV$. Guttation is a cause of transpiration pull.
$V$. Most plants fulfill their water requirement by transpiration pull.

  • A
    $I, II$ and $III$ are correct while $IV$ and $V$ are incorrect.
  • B
    $IV$ and $V$ are correct while $I, II$ and $III$ are incorrect.
