Coniferophyta is one of the divisions of the Kingdom Plantae. Plants under the division Coniferophyta are sometimes called coniferous trees or simply conifers. These conifers are known for bearing cones and they are referred to as coniferophytes. formerly this division was known as Gymnospermae. The word gymnosperm is derived from Greek words, gymno meaning naked and sperma meaning seed, thus conifers and plants that contain naked seeds. The conifers are non-flowering plants whose seeds are not enclosed in ovaries but are arranged spirally giving the shape of the cone. Conifers have sieve cells and albuminous cells which facilitate the movement of food in conifers. Examples of conifers include casuarinas, spruces, cedars, pines, and cypress plants as seen in Figure 1.1 and 1.2
