The vascular seedless plants are utilized as the medicinal plant and fertilizer.

Further Explanation:

The vascular plants are those plants that possess xylem and phloem for the transport of water and food respectively. Plants that have vascular system but are seedless are the members of Pteridophytes.

The characteristics of Pteridophytes:

1. They are seedless and vascular cryptogams: They reproduces through the production of spores.

2. They show alternation of generation as the sporophytic generation alternates with the gametophytic generation: Sporophyte possess true root, stem and leaves.

3. Spores are developed in the sporangia. Both type of spores are developed- homosporous and heterosporous.

4. Sex organs are multicellular and are jacketed.

Some of the example of Pteridophytes are:

1. Equisetum

2. Salvinia

3. Dicksonia

4. Selaginella

The importance of pteridophytes:

1. They are used as cattle feed

2. They are used for medicinal purpose. For example the foliage decoction of Lycopodium is utilized in homeopathy to treat certain disease such as constipation, eczema, diarrhea and inflammation of liver. Equisetumcontains various flavonoid and saponina that have diuretic effect.

3. Marsilea contains starch and are consumed by people as food in some areas.

4. Aquatic pteridophyte such as Azollaare used as a very good biofertiliser.

By far the greatest impact of seedless vascular plants on human life, however, comes from their extinct progenitors. The tall club mosses, horsetails, and tree-like ferns that flourished in the swampy forests of the Carboniferous period gave rise to large deposits of coal throughout the world.

This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.

My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.

This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
