Activity on test for starch in leaves

Posted by Ayushi Kumari 7 years, 9 months ago

CBSE > Class 06 > Science (OLD)

1 answers

Yogita Ingle 7 years, 9 months ago

Iodine solution is used to test leaves for the presence of starch. You need to:

heat a plant leaf in boiling water for 30 seconds (this stops its chemical reactions)
heat it in boiling ethanol for a few minutes (this removes most of its colour)
wash with water and spread onto a white tile
add iodine solution from a dropping pipette

After a few minutes, the parts of the leaf that contain starch turn blue-black.
