  ·          Life cycle of algae –   Diphasic Ø Haplontic v Primitive and simplest type v Prominent phase   - Haploid gametophytic phase v Zygote immediately undergo meiosis to produce haploid zoospore .(  zygotic meiosis)  v Zoospore grows by mitosis to produce Haploid gametophytic generation. v Gametophytic plant produces male and female gametes by mitosis. Examples -  Spirogyra, Oedogonium, Ulothrix, Chlamydomonas, Volvox, Zygnema , Chara.   Ø Diplontic   -   v Prominent phase  - Diploid sporophytic phase v Gametes are produced in the gametangia by meiosis .(Gametic meiosis)   v Zygote developed into a Diploid sporophytic phase by mitosis. Examples-  Caulerpa, Fucus, Sargassum , diatom, Cladophora glomerata Ø Haplo-diplontic - v Well-developed multicellular haploid and diploid phases, called gametophyte and sporophyte respectively. v In sporophytic ...
