Warum haben manche Bäume Nadeln?

Nadeln sind Blätter mit Spezialbau, der Wasser spart, Frost übersteht und kurze Sommer nutzt, ohne dass der Baum jedes Jahr neu austreibt.

Scientists believed that plants lost most of their water through their pores to cool down. They could then simply close these pores in extreme heat.

The study, published in the scientific journal New Phytologist in December, shows that with rising temperatures, plants lose more water through their cuticle, the waxy layer on their leaves, than through their pores. The thinner the cuticle, the greater the water loss.
