The Phanerogams are classified into two parts such as: Gymnosperms are naked seeded plants. Microbial Diversity, Cryptograms and. multicellular. Seeds seem to be one of the factors responsible for the dominance of seed plants in today's flora. Pteridophytes have evolved xylem and phloem for the first time. Thallophytes, bryophytes and, pteridophytes are included in 'cryptogams They have a survival factor the embryo is protected and the stored food that is available is critical and gives them a great selective advantage over free-sporing plants. These plants are terrestrial and can be found in habitats like deserts, mountains, and rainforests. ADVERTISEMENTS: 3. Seeds: structure formed by the maturation of the ovule in seed plant; in fact the seeds represent a portion of the life cycle involving 3 generations of plants (mother sporophyte, megagametophyte, and new sporophyte or embryo).

These scales are subtended by bracts, which are either large and conspicuous. Instead of roots, they have "rhizoids." Pteridophytes occupy the intermediate position between Bryophytes and Gymnosperms (seed plants). Development of distinct embryo after the fertilization in both groups. 1. The key difference between Cryptogams and Phanerogams is that cryptogams are non-seed bearing primitive lower plants while phanerogams are seed bearing higher plants. Cryptogams: Phanerogams: Definition: They are plants or plants like organisms that produce spores. Non-flowering plants are calledA. CryptogamsB. Angiosperms C - Vedantu Palm-like plants found mainly in tropical and subtropical regions. How are angiosperms different than gymnosperms?
