Oct 31, 2023 · Seedless vascular plants are plants that contain vascular tissue, but do not produce flowers or seeds. In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds.
Seedless Vascular Plants, unlike bryophytes, possess vascular tissues – xylem and phloem – that enable them to transport water, nutrients, and sugars more efficiently. This group includes ferns, clubmosses (lycophytes), and horsetails (sphenophytes).
Learn how seedless vascular plants evolved from bryophytes and acquired new traits such as vascular tissue, roots, leaves, and sporophylls. Explore the diversity and importance of ferns, club mosses, horsetails, and whisk ferns.
A third innovation marks the seedless vascular plants. Accompanying the prominence of the sporophyte and the development of vascular tissue, the appearance of true leaves improved their photosynthetic efficiency.
Describe the lifecycle of a fern. Explain the role of seedless vascular plants in the ecosystem. The vascular plants, or tracheophytes, are the dominant and most conspicuous group of land plants. More than 260,000 species of tracheophytes represent more than 90 percent of Earth’s vegetation.
