Question

why are leaves of fine and fir leaves modified to form needles

Answer 1

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

Answer 2

Because evergreen conifers tend to grow in areas where snow falls, needles have adapted to reduce damage from the accumulation of snow. Because needles are narrow, it's difficult for snow to remain on the leaves, and it falls to the ground.Since needles don't shed each fall they can capture sunlight for nearly the entire year. Needles can survive ice and snow. Needles have lower wind resistance than big, flat leaves, so they're less likely to make the tree fall over during a big storm. Needles are tough for insects to eat.
