They may not know what type of life cycles occur in Ectocarpus and Fucus  since students are not expected to know the biodiversity of Algae at generis level. Archegonium is the female sex organ that produces the female gamete or egg. (c) Haplodiplontic or Digenetic Type: In such cases, the diploid zygote instead of germinating into a new plant gives rise to a new sporophytic generation. The most common example is Polysiphonia of order Ceramiales. In this type of life cycle haploid phase of the cells is predominant. In this type of life cycle, gametic meiosis occurs. The haploid plant body may be unicellu­lar, colonial or multicellular. 3.24): There is a single vegetative individual or somatic phase. Archegonium is the female sex organ that produces the female gamete or egg. A haploid life cycle is found in most fungi and in some green algae like Chlamydomonas.

Life cycle of Ectocarpus and Fucus respectively are: (1) Diplontic, Haplodiplontic. In some, the gametophyte is dominant and free-living and the sporophyte is a small and short-lived phase, which is dependent on gametophytes, e.g. Chlamydomonas (Chlorophyta) (Figure 1.19) exhibits this type of life cycle. (c) Haplodiplontic life cycle: This type of life cycle is found in Bryophytes and pteridophytes which is intermediate between haplontic and diplontic type. The Gametophytic stage consists of two stages (i).

Here the life-cycle is triphasic and involves an alternation of two diploid (2n) or sporophytic generations, i.e., carposporophyte and tetrasporophyte with one haploid (n) or gametophytic generation. In a Zygotic Life Cycle, the main stage of an organism's life is haploid (n). Name an alga which is (a) Haplo diplontic (b) Diplontic Solution: Haplo diplontic type of life cycle is exhibited by Ectocarpus, Polysiphonia and Kelps. Concept Enhancer In Ectocarpus sporic meiosis occurs and haploid biflagellate meiozoospores are formed. Question 4. Gametophytic stage is the predominant stage of the moss lifecycle.

The sporophyte generation is represented only by a one-celled zygote. Haplontic Life Cycle ... Gymnosperms, Angiosperms, Fucus, etc. diplontic life cycle — the diploid stage is multicellular and haploid gametes are formed, meiosis is "gametic". haplodiplontic life cycle (also referred to as diplohaplontic, diplobiontic, or dibiontic life cycle) — multicellular diploid and haploid stages occur, meiosis is "sporic". Most algal genera show haplontic life style. It is thus that same zygotic cell that later undergoes meiosis. Four essential kinds of life cycles described are summarized. Diplontic 3. Answers (1) Sporophyte and gametophyte both are photosynthetic and free living. Haplontic Life Cycle The life cycle during which the haploid phase is long and represents almost all the stages of the life except the diploid phase which is represented by zygote is called haplontic life cycle. The life cycle during which the haploid phase is long and represents almost all the stages of the life except the diploid phase which is represented by zygote is called haplontic life cycle. The gametophytes liberate gametes, which fuse to form diploid zygote, which gives rise to a diploid plant. Diplontic 3. In the context of biology, a biological life cycle is a sequence of changes a particular organism undergoes through means of reproduction (sexual or asexual) which finally returns to the original starting phase. lalitranka1006 is waiting for your help.

Fucus, genus of brown algae, common on rocky seacoasts and in salt marshes of northern temperate regions. 3'ATGAAATGCTTTCGCGGG5' 5'TA 3'ATGAAATGCTTTCGCGGG5' 5'TA The Diplontic life cycle is shown by some algae and all the phanerogams or seed-bearing plants. The gametophyte is the dominant phase. Bryophytes. There is two-stage in haplontic life cycle such as gametophyte (haploid) and sporophyte (diploid) which is represented only by zygote. Example − All seed-bearing plants, gymnosperms, and angiosperms, some algae-like Fucus. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. The Hap­loid gametes are developed within the gametangium of the gametophytic plant. 2) diplontic, haplodiplontic. A diploid zygote forms briefly, and then will often enter into a resistant stage, or "immediately" undergo meiosis. The Gametophytic stage consists of two stages (i). The gametes fuse to form Zygote which develops into Sporophyte. The diplontic life cycle is commonly seen in gymnosperms and angiosperms with some variations. The following points highlight the three types of life cycle of plant groups. Haplontic Life Cycle: The plant body is gametophyte (haploid) and sporophyte (diploid) stage is represented only by zygote. The main plant body is thallus, which is diploid.

Haplontic or Zygotic Life Cycle in Algae Haplontic or Zygotic Life Cycle This cycle is characterized by a single predominant haploid vegetative phase, with the meiosis taking place upon germination of the zygote. During sexual reproduction, the life cycle includes the change of ploidy; the alternation of haploid (n) and diploid (2n) stages. ‘The life-cycle is of haplontic type showing alternation of dominant haploid stage with short-lived diploid stage.’ ‘This pattern is reverse of haplontic type.’ ‘If it is primarily haploid, it is said to have a haplontic cycle, and if it is primarily diploid, it is said to have a diplontic cycle.’ Haplontic life cycle refers to a life cycle in which the main form is haploid, with a diploid zygote being formed only briefly while diplontic life cycle refers to a life cycle in which the main form, except for the gametes, is diploid. ... for example in Fucus. Fucus, Sargassum, etc. The gametophytic phase is represented by the single to few celled gametophyte. It is present in the life cycles of mosses (bryophytes), pteridophytes, and gymnosperms.
