This ability to survive cold or dry weather is due to a thick wax cuticle on the needles of conifers, which prevents dehydration through evaporative loss. The tap root system becomes very well developed in gymnosperms and its continuous growth gives better anchorage and absorption of nutrients unlike the ferns in which the roots are always adventitious. 3.
