WebJul 26, 2024 · They may possess root-like, leaf-like or stem-like structures. - The main plant body is haploid. It produces gametes, hence is called a gametophyte. - The sex organs in bryophytes are multicellular. - The male sex organ (antheridium) produces biflagellate antherozoids. The female sex organ (archegonium) is flask-shaped and produces a single … WebApr 19, 2015 · A second issue revealed by including fossil in phylogenetic analyses is a pattern of representational bias in the geological record greatly favouring the larger and more robust vascular plants over bryophytes and bryophyte-like organisms [11,48]. This bias is less evident in the fossil record of dispersed spores, which tend to have similar ...

WebThe adult plant body represents the gametophyte. A short-lived sporophyte occurs as a parasite on the gametophyte.It is the adult plant body in bryophytes. It is either thalloid or in the form of a leafy shoot with stem-like and leaf-like structures. Roots are absent and instead thread-like rhizoids are present. WebSolution. The main plant body of the bryophyte is haploid. It produces gametes, hence is called a gametophyte. The male and female gametes fuse together to form zygote. The zygote produces a multicellular body called a sporophyte which is diploid. The sporophyte is not free-living but attached to the photosynthetic gametophyte. simon wakelin\u0027s daughter bianca wakelin

WebHowever, bryophytes have multicellular reproductive structures, whereas those of green algae are unicellular, and bryophytes are mostly terrestrial and have complex plant bodies, whereas the green algae are primarily aquatic and have less-complex forms. WebThe plant body of bryophyte A can be prostrate or erect B have true roots, leaves and stem C have root for anchorage D grows mostly in arid conditions Solution The correct option is A … WebSeedless nonvascular plants are small, having the gametophyte as the dominant stage of the lifecycle. Without a vascular system and roots, they absorb water and nutrients on all their exposed surfaces. Collectively known as bryophytes, the three main groups include the liverworts, the hornworts, and the mosses. simon wakefield cardiff
