Which are vascular plants? a. ferns and seed plants b. mosses and seed plants c. seed plants and mycorrhiza d. ferns and mycorrhiza

The right option is; A. ferns and seed plants

The vascular plants are plants that possess a system of vessels within them which conducts or circulates water, minerals, and other substances throughout the plant. The vessels (xylem and phloem) are usually located in the plant’s body parts such as stems, roots and leaves. Vascular plants are grouped into two based on their mode of reproduction. Vascular plants that reproduce using spores are known as ferns (a seedless vascular plant) while those that reproduce by producing seeds (seed plant) are grouped as either gymnosperms or angiosperms. Vascular plants include the ferns, the seed plants such as cedars, spruces, and sunflowers.
