The plant group that produces spores and embryo but lacks vasular tissues and seeds isA. PteridophytaB. RhodophytaC. BryophytaD. Phaeophyta |
|
Answer» Correct Answer - C (c) Bryophytes consist of thalloid body, attached to the substratum by hair-like structures called rhizoids (true roots are absent), these lack vascular tissue (xylem and phloem) and require water at the time of fertilisation. Bryophytes exhibit alternation of generation. The haploid gametophyte (producing gametes for sexual reproduction) alternates with diploid sporophyte (producing spores for asexual reproduction). Production of large number of spores is for increasing the chances of chances of survival and is an adaptation to land conditions. |
