Detailed explanation-1: -Conifers can be identified by the needles, cones and sometimes the color of the bark. Pine needles are in groups of 2, 3 or 5 and are longer than spruce and fir needles. Spruce needles are single needles emanating around the branch and have four sides.

Detailed explanation-2: -Conifers generally have persistent foliage consisting of needles or scales.

Detailed explanation-3: -Coniferous forests consist mostly of conifers, which are trees that grow needles instead of leaves and cones instead of flowers. Conifers tend to be evergreen-they bear needles all year long. These adaptations help conifers survive in areas that are very cold or dry.

Detailed explanation-4: -All but 15 types of conifers are evergreen, one of the familiar characteristics of this group of plants. They grow with a straight, central trunk bearing circles of horizontal branches, and the branching may become increasing complex as the tree gets older. Conifers also have a wide variety of distinctive bark.
