Answer 2

Answer:

Explanation:

CACTUS GROW IN DESERT REGIONS AND SO THE LEVEL OF ESCAPE OF WATER FROM THEIR LEAVES IS VERY HIGH DURING DAY.

TO MINIMIZE THIS EXCESSIVE LOSS OF WATER FROM THEIR BODY, THEY HAVE LEAVES IN THE FORM OF SPINS AND THORNS AND ALLOW VERY LITTLE OR NO LOSS OF WATER FROM THEIR BODY.

THIS IS A KIND OF ADAPTATION BY THESE DESERT PLANTS TO SURVIVE IN HARSH CONDITIONS OF DESERT.
