Question

How Can one destrach leaf of Potter plant without plucking

Answer 1

Answer:

a) If a potted plant is kept in darkness for 48 hours, all starch in its leaves should have been changed to sugars and conducted out of the leaves. This is destarching.

(b) To check on the destarching, single of the leaves or part of a leaf should be tested with iodine  to make sure the leaf is free from starch.
