Question

The plant kingdom is comprised of four major divisions (phyla), each of which has evolved to be more complex than the next. Identify the division based on the characteristics given below.

This division of the plant kingdom lacks vascular tissues and must live in wet environments, as their reproduction relies on water since they produce swimming sperms. The gametophyte generation is the dominant generation in this group of plants.

• A. Angiosperms
• B. Bryophytes
• C. Conifers
• D. Phaeophyta
• E. Pteridophytes (Tracheophytes)

Answer 1

The correct option is B Bryophytes

Bryophytes lack vascular tissues and must live in wet environments, as their reproduction relies on water since they produce swimming eggs and sperm. That is why they are also called amphibians of plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction. In this group of plants, a multicellular diploid sporophyte lives as a parasite on an independent multicellular haploid gametophyte. Bryophytes include the various mosses and liverworts that are found commonly growing in moist shaded areas in the hills.

Hence the correct option is B.
