Seeds, in gymnosperms are naked whereas in angiosperms, they are enclosed in fruits.
The four main groups of plants are mosses, ferns, gymnosperms, and angiosperms. Mosses are non-vascular plants, ferns are seedless vascular plants, gymnosperms have naked seeds (like pine trees), and angiosperms have seeds enclosed in fruits (flowering plants).
Ferns are the most commonly known seedless vascular plant, while there are also horsetails and club mosses. Liverworts are not seedless vascular plants -- they are actually nonvascular.

Gymnosperms were the first plants to reproduce using seeds. Unlike their predecessors, the seedless vascular plants, gymnosperms developed seeds that provided protection and nourishment to the developing embryo. This adaptation allowed gymnosperms to thrive in various environments and contributed to their evolutionary success. Additionally, gymnosperms reproduce via cones, which contain the reproductive structures for both male and female gametes.
Whisk ferns are seedless vascular plants that only have vascular tissues in their stem.
The four main groups of plants are mosses, ferns, gymnosperms, and angiosperms. Mosses are non-vascular plants, ferns are seedless vascular plants, gymnosperms have naked seeds (like pine trees), and angiosperms have seeds enclosed in fruits (flowering plants).
All vascular plants do not bear seeds. For example plants belonging to Pteridophyta are seedless and those of Gymnosperms and Angiosperms bear seeds.
they are seedless vascular plants
There are only three (not four) groups of vascular plants. The vascular tissue is used to transport nutrients and water through the plant. There is seedless vascular plants, angiosperms, and gymnosperms.
Two ways scientists can divide vascular plants are into seedless vascular plants and seed plants. Seedless vascular plants are comprised of the lycophytes (club mosses, spike mosses, and quillworts) and pterophytes (ferns, horsetails, and whisk ferns) and do not produce seeds. Seed vascular plants are comprised of gymnosperms (ginkgo, cycads, gnetophytes, and conifers) and angiosperms (flowering plants). Gymnosperms can be distinguished by their "naked seeds," while angiosperms produce flowers and fruits.
Non-vascular plants (mosses and their relatives), Seedless vascular plants (ferns and their relatives), Gymnosperms (cone-bearing plants), and Angiosperms (flowering plants)
There is one division of angiosperms, Magnoliophyta, which is divided into two classes: monocots and dicots. Monocots are angiosperms with seeds having single cotyledons and dicots are the ones with seeds having two cotyledons.
Not all vascular plants have seeds. Some plants (like club mosses) are vascular and produce spores. For example the phylum Lycophyta are club mosses and quill-worts. these plants produce spores but still have vascular roots, stems, and one vascular vein in each leaf.
Seedless Vascular Plants that withhold gammets and spermers
Three groups of seedless vascular plants: Ferns, Mosses, Liverworts.
Ferns are the most commonly known seedless vascular plant, while there are also horsetails and club mosses. Liverworts are not seedless vascular plants -- they are actually nonvascular.
