describe the structure and reproduction in
ulva with reference to isomorphic alternation of generation
Answers
Answer:
Ulva has a alternation of generations. Biflagellate isogametes are fashioned through positive cells of the haploid, gametangial plant.
Explanation:
In a few species, together with the alga Ulva lactuca, the diploid and haploid paperwork are certainly each free-dwelling unbiased organisms, basically same in look and consequently stated to be isomorphic. The free-swimming, haploid gametes shape a diploid zygote which germinates right into a multicellular diploid sporophyte.
In ulva the haploid zoospores provide upward thrust to the gametophytes. Both types of flowers are morphologically same and consequently ulva suggests an isomorphic alternation of generations.
In an isomorphic alternation of generations (observed in a few algae, for example) the sporophyte and gametophyte are morphologically comparable or same; in a heteromorphic alternation of generations they're dissimilar (e.g. in mosses the gametophyte is the dominant and conspicuous generation, while in better flowers.
