Solution
The correct option is A Ringing experiment for translocation of sap
The demonstration in the experiment is a ringing experiment for the translocation of sap.
Translocation is the process of transporting liquids from leaves to other tissues throughout the plant. Movement of water from the soil to the leaves is done in xylem vessels.
Organic materials mainly produced in the leaves are moved around the plant in the living cells of the phloem.
Unlike xylem, which is composed of dead cells, the phloem is composed of living cells that transport sap. The water-based solution rich in sugars made by the process of photosynthesis is called sap.
In the ringing experiment, a ring of bark is scraped away that also removes the phloem.
After a while sugar is transported down the stem but it is stopped by the ring. This means, a bulge above the ring forms of sugar. This suggests that sugar moves down the stem in the phloem. So, the correct answer is option A.
