AP BIOLOGY

Detailed explanation-1: -Unlike vascular plants, non-vascular plants do not possess roots, stems, or leaves. Seedless vascular plants are a part of the tracheophytes. They possess vascular tissues such as xylem and phloem, but do not produce seeds or flowers for propagation.

Detailed explanation-2: -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.

Detailed explanation-3: -Most seedless vascular plants also have true roots and leaves. Furthermore, the life cycles of seedless vascular plants are dominated by diploid spore-producing sporophytes, rather than gametophytes. However, like nonvascular plants, seedless vascular plants reproduce with spores rather than seeds.

Detailed explanation-4: -In Summary: Seedless Vascular Plants With the development of the vascular system, there appeared leaves to act as large photosynthetic organs, and roots to access water from the ground. Small uncomplicated leaves are microphylls. Large leaves with vein patterns are megaphylls.
