Detailed explanation-1: -The Pteridophytes are the most primitive vascular plants, having a simple reproductive system lacking flowers and seed. Pteridophytes evolved a system of xylem and phloem to transport fluids and thus achieved greater heights than was possible for their avascular ancestors.

Detailed explanation-2: -Pteridophytes are primitive vascular plants, commonly known as ferns. Unlike other vascular plants, the life cycle of ferns is split between free-living gametophyte and sporophyte phases.

Detailed explanation-3: –Among those, primitive vascular plants come under the pteridophytes. They are commonly called ferns.-Ferns are usually well-differentiated which means they have well-developed roots, stems and all but when to come to life cycle it occurs by the spore dispersal, hence it is considered as the most primitive plant.

Detailed explanation-4: -Collectively known as bryophytes, the three main groups include the liverworts, the hornworts, and the mosses. Liverworts are the most primitive plants and are closely related to the first land plants.
