Morphology. Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves.

But trees that produce flowers do not produce cones, and vice versa. Upstaged by the flamboyant flowers of high spring—azaleas and rhododendrons, peonies, irises, and poppies—conifers are often overlooked this time of year, which is a shame. The Life Cycle of Conifers Conifers belong to the botanical class gymnosperms that reproduce through seeds but the seeds remain naked and do not bloom into flowers. Gymnosperm means "naked seed" as the seeds are not produced inside a fruit as they are in the flowering plants. The characteristics that differentiate angiosperms from gymnosperms include flowers, fruits, and endosperm in the seeds. The gymnosperms were for a long time the dominant plants on Earth but have been overthrown since the evolution and diversification of the angiosperms. As with all species of conifers, spruces have needle-like leaves. The gametophyte generation, that is, the generation that is the larger, more easily seen, is the one that produces gametes, not the one that produces spores.

Most do fine in acid soil, but none require acid soil.There are also conifers tolerant of alkaline soils (some junipers and yews, for example), but again, none require such soil. Conifers, however, still dominate in cold and dry environments, as a waxy covering (cuticle) on their needle-like leaves allows them to survive in more extreme conditions than the angiosperms. All living conifers are woody plants, and most are trees, the majority having monopodial growth form (a single, straight trunk with side branches) with strong apical dominance.Many conifers have distinctly scented resin, secreted to protect the tree against insect infestation and fungal infection of wounds. Conifers that bare their male and female flowers on different trees, such as Juniperus and Taxus are referred to as being dioecious. What is unique about dicots leaves? Conifers are gymnosperm, a group of plants producing naked seeds, i.e., seeds produced are not enclosed in fruits, but in a very thin layers of cells call intergument, born on cone like structure.
