Since the multicellular diploid individual is a diploid and the gamete undergoes meiosis, it is called a diplontic life cycle. 1.”Life cycles algae & plants.” Afzender. This type of life cycle involves the alternation of two vegetative individuals, the haploid gametophyte and diploid sporophyte. This way, the organism ends its diploid phase and produces several haploid cells. Haploid gametes are produced from individual cells of the diploid cells through meiosis. During gamete formation, meiosis takes place in the formation of haploid (n) gametes. Identify the life cycle pattern? In a diplontic life cycle, the majority of the organism's life is spent with most of the cells in the body being diploid. Sporophyte and gametophyte both are photosynthetic and free living. Most organisms that have a diplontic life cycle start from the fusion of two haploid gametes. There are four types of life cycle in algae such as Triphasic Life Cycle, Diplohaplontic Life Cycle, Diplontic Life Cycle, and Haplontic Life Cycle. Consider the given statements : a.

The cells of the diploid organism divide by meiosis to form the haploid gametes. Anybody can ask question and anybody can answer. The Haplontic Life Cycle is a diphasic cycle and considered as the simplest and most primitive type of lifecycle. After that a new free-living gametophytic plant is developed by the germination of carpospores. Haplodiplontic life cycle mostly found in Chlamydomonas, Ulothrix, Oedogonium, Spirogyra. In the diplontic life cycle, the only haploid cells are the gametes. Gametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”). During fertilization, the haploid (n) gametes fuse together in the formation of a diploid (2n) zygote, and it mitotically divides and produces a multicellular diploid (2n) organism. Life cycle of Ectocarpus and Fucus respectively are (A) Haplontic, Diplontic (B) Diplontic, Haplodiplontic (C) Haplodiplontic, Diplontic (D) Haplodiplontic, Haplontic (NEET 2017) 4. Save my name, email, and website in this browser for the next time I comment. After meiotic division, the sporophytic plant develops zoospores which are then germinate and produce a haploid gametophytic plant. Haplontic life cycle involves the formation of a haploid (n) single cell by the meiosis of a diploid (2n) zygote. Then the carposporophyte form carposporangium which is then develop a haploid carpospores. In this type, the gametophytic plant (haploid) forms gametes, which then undergo sexual reproduction and form zygote. A sporophyte (/sp??ro? In the whole cycle, zygotes are the only diploid cell; mitosis occurs only in the haploid phase. 14 Aug. 2017. 1. There is two-stage in haplontic life cycle such as gametophyte (haploid) and sporophyte (diploid) which is represented only by zygote. After that, the carpospores are germinated and form diploid tetrasporophytic plants. The cycles differ in … They are, haplontic, diplontic and haplodiplontic. The reproduction of the haploid gametophytic plant is followed by the sexual method whereas the diploid sporophytic plant by the asexual process. But modern taxonomy gives equal … Terms of Use and Privacy Policy: Legal. (iv).
