Draw the life cycle pattern exhibited by all Bryophyte and Pteridophytes.
Answers
Bryophytes and Pteridophytes show an intermediate condition called the haplo-diplontic life cycle, where phases are multicellular. But the dominant phase differs. In Bryophytes, the dominant phase is the gametophyte and in Pteridophytes, it is the sporophyte.
Life Cycle of Pteridophytes. Ferns have a life cycle dependent on spore production. ... Pteridophytes are similar to bryophytes in that they are seedless, flowerless plants that depend on the production of spores to propagate. They undergo photosynthesis, so they are autotrophs, meaning they make their own food.As do all plants, bryophytes alternate a gametophytic generation with a sporophytic one (a sporic meiosis, a life cycle in which meiosis gives rise to spores, not gametes). Each of the haploid (1 n) spores is capable of developing into a multicellular, haploid individual, the gametophyte.Bryophytes and Pteridophytes show an intermediate condition called the haplo-diplontic life cycle, where phases are multicellular. But the dominant phase differs. In Bryophytes, the dominant phase is the gametophyte and in Pteridophytes, it is the sporophyte.Pteridophyte are vascular plants i.e., plants with xylem and phloem, that reproduce and disperse via spores. ... Bryophytes have no true roots while pteridophyte have true roots. Bryophytes have no vascular tissues while pteridophytes have vascular tissues.Bryophytes and pteridophytes grow in moist and shady places because they do not have the ability to withstand the sun light and they are adapted for shadow and moisture places. Plants like bryophytes and pteridophytes are usually very delicate and cannot withstand sun rays.So the prefer growing in moist shady places.
