Detailed explanation-1: -The leaves of conifers are either called needles or scales. These represent the two different leaf types commonly found on conifers. Needles are the long, thin leaves we commonly associate with pine trees. Scale-like leaves are more common to cypress and cedar trees.

Detailed explanation-2: -Most conifers such as fir, pine, spruce and larch have needle-like leaves. Coniferous trees have long, thin leaves that resemble needles. They are also cone shaped. This allows the snow to slide off and prevents accumulation of snow on tree branches.

Detailed explanation-3: -For example; pines and cedars have needle shaped leaves, whereas scale like leaves are borne on matured cypress trees. Majority of the coniferous trees are evergreen, meaning they retain their green foliage throughout the year.

Detailed explanation-4: -Conifer trees grow in hilly areas and are evergreen in nature. They have needle-shaped leaves to reduce water loss. eg. Pine tree.

Detailed explanation-5: -A conifer is a cone-bearing tree which almost always has modified leaves known as needles, and is typically evergreen. All true conifers have needles, but they’re a bit different in nature.
