The bimodal theory of translocation was put forth by

"Girdling Experiment" was performed by plant physiologists to identify the plant tissue through which:

Can girdling experiments be done in monocots? If yes,how? If no,why not?

Arrange the following events of mass flow of organic material in sequence:
$I$. Sugars are transported from cell to cell in the leaf
$II$. Food is synthesized in form of glucose by leaf cells
$III$. Movement of water takes place into sieve tube elements
$IV$. Downward movement of sugar occurs in the stem
$V$. Solutes are actively transported into the sieve elements

Translocation may be affected by

In vascular plants,what is the nature of the transport of organic and mineral nutrients in the phloem?
