Question

Pteridophytes are not completely successful terrestrial plants beacause ?

Answer 1

Pteridophtyes are a phylum of plants. They are the vascular plants (those having xylem and phloem tissues) that reproduce by releasing spores rather than seeds, and they include the highly diverse true ferns and other graceful, primarily forest-dwelling plants. There are about eleven thousand different species of pteridophytes, making them the most diverse land plants after the flowering plants (angiosperms). Pteridophytes may represent the closest living relatives (sister group) to the seed plants. (Seed plants include the angiosperms, the conifers, and a smaller assortment of other plants.)

As in seed plants, the greatest diversity of pteridophytes is found in the tropics, with only about six hundred species adapted for life in temperate climates. Species living today are relics of ancient lineages that once dominated

Ferns reproduce by releasing spores rather than seeds.

Answer 2

Hey Dear,

◆ Pteridophytes -

• Phylum pteridophytes include vascular plants that produce spores.
• These are terrestrial plants & are adapted accordingly - presence of vascular bundles, absence of seeds & flowers.
• These plants are found in moist, damp & shady places.

# Pteridophytes are not successful terrestrial plants because -

• Though these plants are terrestrial, presence of water is mandatory for their fertilization.
• Thus pteridophytes are said to be not completely successful terrestrial plants.
