Detailed explanation-1: -Conifer trees grow in hilly areas and are evergreen in nature. They have needle-shaped leaves which help conifers to survive in cold, harsh climates. These leaves are tough and coated with a waxy outer coat. They also reduce water loss.

Detailed explanation-2: -Coniferous trees have small, waxy and usually narrow leaves (needles or flat scales). ‘Coniferous’ means that it is a cone-bearing tree. The most common conifers are spruces, pines and firs. Alternative names used for coniferous trees are evergreens, softwoods and (appropriately enough) conifers.

Detailed explanation-3: -Japanese falsecypress (Chamaecyparis pisifera), Arizona cypress (Hesperocyparis arizonica), eastern arborvitae (Thuja occidentalis), and Leyland cypress (X Hesperotropsis leylandii) are examples of conifers with scale-like leaves.

Detailed explanation-4: -Cedar trees’ leaves are needle-like, but they are soft, like those of ferns. They are cone-bearing and evergreen. The Northern White Cedar bears cones and is a true conifer. Some trees identified as cedar in the US are not actually cedar, though.
