Explanation

Evergreen means the plants which have leaves for all four season and opposite to that deciduous trees lose/shed their leaves in either winter or dry season. Pinus of gymnosperms is an evergreen tree. Flowering plants lose/ shed their leaves in very cold atmosphere and become dormant.
But in pinus due to its thick bark, needle like leaves and sunken stomata the rate of transpiration is reduced. Due to cold regions, less rain fall physiologically and physically, snow fall, cold temperature, open house, absorption by roots is decreased.
But pinus is well adapted in this condition. It continues to make food during this season also and develops dominantly on other plants. It shows that pinus is an evergreen plant. It does not shed leaves so needles are available in any condition.
