Gymnospermeillä

Gymnospermeillä, commonly known as gymnosperms, are a group of seed-producing plants that reproduce using seeds, but do not produce flowers or fruits. They are one of the two major groups of seed plants, the other being angiosperms. Gymnosperms are further divided into two subclasses: conifers and cycads. Conifers, which include familiar trees like pines and spruces, are the most diverse group of gymnosperms. Cycads, on the other hand, are less diverse and are often found in tropical regions. Gymnosperms are characterized by their naked seeds, which are not enclosed in an ovary or fruit. Instead, they are typically borne on the scales of cones. The seeds of gymnosperms are usually enclosed in a woody structure, such as a cone or a seed scale. Gymnosperms have been around for over 300 million years and have played a significant role in the evolution of plants. They are found in a variety of habitats, from tropical rainforests to temperate forests and even in arid regions. Gymnosperms are an important part of the global ecosystem, providing habitat and food for many species.
