Question

Identify the process taking place in this experiment.

• A. Ringing experiment for translocation of sap
• B. Demonstration of root pressure
• C. Eosin test to demonstrate ascent of sap
• D. Demonstration of transpiration

Answer 1

The correct option is A Ringing experiment for translocation of sap

The image shows Ringing experiment for translocation of sap.

The ringing experiment involves removing a selected part of a stem tissue in the form of a ring or a girdle. It is a procedure in which the outer tissues of a stem are removed, leaving only the xylem and pith intact. Water transport up the stem is unimpeded by such a process, whereas food transport down from the leaves stops at the ring, thus demonstrating the roles of xylem and pholeom respectively.
