WHY DO EVERGREEN TREES STAY GREEN ALL YEAR LONG?

The question was why do evergreens stay green all year long?

The reason why evergreens stay green all year long, is because they have leaves that look like needles. Those needles carry less water than regular sized leaves which keeps them from freezing in the cold weather. Only a few needles fall off of the trees, so it allows the tree to do photosynthesis all year long. The needles stay green which is why they name those trees evergreens. Evergreens produce photosynthesis all year long, and the needles have a special wax coating which helps keep doing photosynthesis so the leaves dont lose their chlorophyll.
