By cutting the ring of phloem,which of the following processes is affected?

Which of the following facts proves that the translocation of materials occurs through the phloem?

Which of the following phenomena is not associated with root pressure?

Analogy type questions:
$(1)$ Stomata : Transpiration :: Hydathode : ..........
$(2)$ Phloem : Translocation of sugars :: Xylem : ..........

During which process in leaves is the water potential positive?

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.
