  • 6. When it's time, the Pine cone with seeds. scales of the cone open and the seeds fall to the ground.
  • 7. Coniferous trees with their long needle like leaves thrive where summers are short and cool and winters long and harsh, with heavy snowfall that can last as long as 6 months.
  • 8. These needles are pretty amazing adaptations. It is their long thin shape and wax covering that slows down evaporation so the tree doesn't lose much water.
