Question

Answer 1

needle-like leaves helps in the prevention of water loss

Answer 2

Evergreen conifers are some of the oldest trees in the world, and for good reason. The needles hold several adaptive qualities that allow them to survive growing in areas that challenge most plants, such as places with heavy snowfall or where soils become very dry. These leaf adaptations make evergreen conifers remarkably resilient in the face of conditions that might kill their deciduous broadleaf cousins. Some of these adaptations serve multiple purposes, like preserving water and protection from the cold.
