Bryophyte And Pteropyte Life Cycles - A Compare/Contrast

Bryophyte and Pteropyte Life Cycles - A Compargon/Contrast Although Bryophytes and Pterophytes are both plant divisions with a common ancestor, they have small-scale in common. While Bryophytes (mosses) are generally nonvascular and very condensed in height, Pterophytes (ferns) are vascular plants that usually grow more taller than mosses. While the dominant generation in mosses is the gametophyte, ferns exhibit the sporophyte generation. The exposit of their alternations of generation vary as well, although both have diploid and haploid stages.

Alteration of generations is defined as a feeling cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte. Meiosis in mosses produces haploid spores. This process occurs in a sporangium, a encapsulate in fungi and plants in which meiosis takes place and haploid spores develop. After fertilization, the sporophyte zygote grows out of the parent gametophyte. At the ratiocination of this stalk is t...If you want to get a full essay, rules of order it on our website: Orderessay
