On this basis, life cycle may be three types: (i) Uniphasic: In this life cycle, only one visible generation is distinct either haploid or diploid and the life cycle are called haplontic, or diplontic. The haploid plant body is termed gametophyte while the diploid plant body is called sporophyte. Zygotic meiosis occurs. Sporophyte generation is very reduced & is represented by a single cell i.e., the zygote that immediately undergoes meiosis. The gametophytic phase is represented by the single to few-celled haploid … Haplontic Life Cycle 2. From wikipedia > Biological Life Cycle:.

Diplontic Life Cycle. Key Difference – Haplontic vs Diplontic Life Cycles 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. Anonymous. Diplontic refers to diploid multicellular life. As adjectives the difference between haplontic and diplontic is that haplontic is (biology) describing an organism that is haploid for most of its life cycle but that briefly has a diploid zygote while diplontic is of or pertaining to a diplont.

(ii) Diphasic: In this type, both the haploid and diploid generations are distinct. In the genus Laminaria these gametophytes, the haploid life forms, appear as small ramified filaments. monobiontic, dibiontic, haplontic, diplontic. The diplontic life cycle involves the formation of diploid gametes. haplontic life cycle - the haploid stage is multicellular and the diploid stage is a single cell, meiosis is "zygotic". Ø Life cycle is diphasic, but the prominent phase is diploid sporophytic phase. It is thus that same zygotic cell that later undergoes meiosis. In the alternation of generation of Laminaria sp. in this kind of the life cycle the main dominant stage is the diploid stage. Haplontic Life Cycle. However, in some other Brown algae the oosphere-producing oogonia and the sperm cells producing antheridia are either together in the same receptaculum (e.g. ADVERTISEMENTS: Some of the important types of life cycles found in yeast are as follows: Guilliermond (1940) has recognized three main types of life cycles in the yeast.
Reason: Zygotic meiosis occurs in Spirogyra. In a sexually reproducing plant, there is an alternation of generation between a haploid and a diploid phase of plant bodies. Diplontic life cycle. Diplontic. Ask Question + 100. In sporic meiosis also commonly known as intermediary meiosis, the zygote divides mitotically to produce a multicellular diploid "sporophyte". Ø This type is just a reversal of the haplontic type of life cycle. 4 years ago. The haplontic life cycle is exhibited by most members of Chlorophyta where the main plant body IS haploid and reproduces by vegetative multiplication or formation of mitospores (spores formed as a result of mitosis). ... human diplontic life cycle: 1.
