Because ferns are vascular plants
There are more species of ferns than club mosses, with over 10,000 species of ferns compared to around 1,200 species of club mosses. Ferns are a diverse group of vascular plants that have been around for millions of years and are found in a wide range of habitats worldwide. Club mosses, although also ancient plants, are a smaller group known for their small, spore-producing structures.
Ferns are considered more advanced than mosses because they have vascular tissues like xylem and phloem, which mosses lack. Vascular tissues allow ferns to transport water and nutrients more efficiently throughout the plant, enabling them to grow taller and have more complex structures. This gives ferns an evolutionary advantage over mosses in terms of size and complexity.
Subphylum Filicinophyta (ferns) are considered more advanced than subphylum Lycopodiophyta (club mosses) because they have roots, stems, and leaves, as well as a more developed vascular system that allows for better water and nutrient transport. Ferns also have more complex reproductive structures and lifecycles compared to club mosses.
Club mosses are vascular plants with erect stems that bear spores in club-shaped, cone-like structures. And True mosses are non-vascular plants which have simple leaflike, rootlike, and stem like parts. They're not true leaves, roots, or stems because they lack vascular tissues.
Ferns are vascular plants. They contain vascular strands that allow water and nutrients to be transferred throughout the the plant. Mosses lack the vascular strands(or tissue) causing the mosses to have a much smaller stature because they are not able to transfer nutrients very well.
Subphylum Filicinophyta (ferns) have large, complex leaves called fronds, while subphylum Lycopodiophyta (club mosses) have smaller leaves and simpler structures. Ferns also have a more advanced vascular system that includes true roots, stems, and leaves, whereas club mosses have simpler, dichotomously branching stems. Additionally, ferns produce spores in structures called sporangia, which are typically clustered in groups called sori, while club mosses have strobili that contain spore-producing structures.
Because mosses rely on diffusion to transport water up the cells and do not have the vessels found in plant cells that allow water to be carried upwards.
Any of various vascular plants that reproduce by means of spores rather than by seeds, including the ferns and related plants, such as club mosses and horsetails.
True mosses generally grow taller than club mosses. True mosses, also known as Bryophyta, have a simple leafy structure and can grow up to several inches tall. In contrast, club mosses, also known as Lycopodiophyta, have a more complex vascular structure and usually grow lower to the ground, forming dense carpets or small clusters.
Ferns and mosses are examples of plants that reproduce via spores rather than seeds. Spores are single-celled structures that can develop into new plants under suitable conditions.
Because ferns (Pteridophyta) and gymnosperms are part of the larger category of vascular plants (Tracheophyta) and share common features that mosses lack. Perhaps also because of the spurious notion that "seed ferns" (Pteridospermatophyta), the ancestors of the gymnosperms, evolved from ferns. In fact, "seed ferns" are a large, heterogeneous category of plants which are generally believed to be only distantly related to true ferns.
There are more germs than club mosses primarily due to differences in reproductive strategies and adaptability. Germs, or microorganisms, reproduce rapidly and can thrive in a wide range of environments, leading to their vast numbers. In contrast, club mosses are vascular plants that have more complex life cycles and ecological requirements, limiting their distribution and abundance. Additionally, the ecological niches occupied by germs are often less competitive, allowing them to proliferate in diverse habitats.
