This kind of vascular plant is usually characterized as a seedless vascular plant. 2. Seedless vascular plants. Vascular plants may be seedless or seeded. Gymnosperms. Seedless vascular plants require water to reproduce. 1 (17.1-17.2) Key Plant Adaptations to Life on Land 2 (17.2) Compare the bryophytes, seedless vascular plants, gymnosperms, and angiosperms 3 (17.8) describe the parts of a … Among lower vascular plants, ferns are the best example. Non-vascular plants are not able to transport water so they must be small, in a moist environment, and short. Seedless vascular plants express the typical life cycle pattern called alternation of generations found in many algae and members of the kingdom Plantae. Vascular plants are divided into two groups; non-seed plants or lower vascular plants or cryptograms and seed plants or higher vascular plants or phanerogams. The gametes merge physiologically and give rise to new plant. Another major difference between seed-bearing and seedless vascular plants is, in the former, reproductive tissues like flowers are aerial in nature and grow high above the ground. The gametes from the gametophyte generation give rise to sporophyte generation. Both male and female gamete-producing organs exist on same plant. On the other hand, in the latter, the gametophyte, which contains the sexual organs (antheridia and archegonia), grows close to … characteristics of club mosses and ferns-Dominant sporophyte generation-xylem, phloem, lignin(2nd most abundant organic compound) ... difference between homospory and heterospory. They may reproduce sexually or asexually. Key Takeaways Key Points. 6), the most notable difference is the relative sizes of the sporophyte and gametophyte. Ferns are found in humid and hot areas. The spore from the sporophyte generation gives rise to gametophyte generation. The life cycle of seedless vascular plants alternates between a diploid sporophyte and a haploid gametophyte phase. seedless vascular plants. It allows for vascular continuity to be maintained between the root and the shoot or the shoot and any structures arising from it. 3 Seedless vascular plants reproduce through unicellular, haploid spores instead of seeds; the lightweight spores allow for easy dispersion in the wind. Seed plants are either gymnosperms or angiosperms. Seedless vascular plants have the same tissue but reproduce by spores and lack flowers and seeds. 1. They have developed specialized tissue that transports water and nutrients to all parts of the plant. In mosses the haploid gametophyte is the dominant generation, whereas in ferns the … Those vascular plants that undergo reproduction using spores are referred to as ferns. Please update your bookmarks accordingly. Seed plants do not need water to reproduce. The lower vascular plants include plants like ferns that although are adapted to survive on land still have some characteristics of their aquatic ancestry. We have moved all content for this concept to for better organization. As in all vascular plants, the diploid sporophyte generation, which produces haploid spores for the asexual reproductive phase, is dominant. When one compares the life cycle of a moss to that of a fern (a seedless vascular plant; Fig. Psilophyta If we could have wandered about on earth in the Devonian period the only conspicuous land plants would have been something like the whisk fern, Psilotum .
