TAKE 2 GLASS JARS AND FILL THEM WITH WATER. NOW TAKE TWO ONION BULBS AND PLACE ONE ON EACH JAR. OBSERVE THE GROWTH OF ROOTS IN BOTH THE BULBS FOR FEW DAYS. MEASURE THE LENGTHS OF ROOT ON DAY 1 , 2,AND3 . ON DAY 4 CUT THE ROOT TIPS OF THE THE ONION BULB IN JAR 2 BY 2 CM. AFTER THIS OBSERVE THE GROWTH OF BOTH.
