The sporophytes create spores by meiosis which disperse by wind and water to form new gametophytes. Mosses have a unique life cycle in which the haploid stage the gametophyte n is the dominant generation.

In the sporangium at the time of spore formation.
. The spores divide and produce male or female gametophytes. In the archegonium of the gametophyte generation. Fertilization occurs in the archegonium to form a diploid zygote.
In the sporangium at the time of spore formation. Once the egg is fertilized a diploid sporophyte develops 2n and produces spores which are dispersed. In the spores after being released by the sporophyte d.

In the moss life cycle fertilization takes place in the archegonium of the gametophyte. Where does meiosis take place in the moss life cycle. The sperm enter the archegonium through the narrow channel in its neck.
In Gymnosperms it occurs in microsporangium and megasporangium to produce niicrospores pollen grains and. Where does meiosis take place in a moss. In the archegonium of the gametophyte generation.
Also Know where does fertilization take place in the moss life cycle. The sporophyte of mosses. In liverworts and mosses it occurs in spore mother cells found in capsule.
In the sporangium at the time of spore formation. Where does meiosis take place in the moss life cycle. Where does fertilization take place in the moss life cycle.
Each archegonium holds one egg in a swollen section called the venter. Both these stages are haploid or gametophytic. In the spores after being released by the sporophyte.
Meiosis takes place in the tiny sprorophyte stage of bryophytes which are attached to and dependent on the much larger gametophyte stage. Where does meiosis take place in the moss life cycle. When and where does reduction division take place in the life cycle of a liverwort a moss a fern a gymnosperm and an angiosperm.
The reduction division takes place in the stamen by producing haploid pollen grains and in the ovary of the pistil which produces egg and then these two fuse together and form a sporophytic plant body. In the antheridia and archegonia of the gametophyte generation. One may also ask what is the life cycle of a moss.
Asked Aug 1 2017 in Biology by Kundan kumar 512k points plant kingdom. Where does fertilization take place in the moss life cycle. In the archegonium of the gametophyte generation c.
Pollen cones contain microsporangia that undergo meiosis and develop into. The moss life cycle The mosses have an alternation of generations with a haploid gametophyte stage alternating with a diploid sporophyte stage. Moss In mosses the primary protonema developed in the first stage develops into the secondary protonema.
In meiosis 1 reduces ploidy level from 2n to n which means chromosome number 46 will reduce to 23 while. Correspondingly what is the life cycle of a moss. Some successfully end up on female gametophyte moss plants and are chemically attracted to the archegonium.
Meiosis produces 4 haploid cells. Where does meiosis take place in the moss life cycle. Meiosis takes place in a specialized structure on the sporophyte the sporangium producing spores not gametes.
In the antheridia and archegonia of the gametophyte generation b. It produces haploid spores. In the sporangium at the time of spore formation.
In all these cases meiosis is sporic and occurs at the time of asexual reproduction. Which set of terms represents a haploiddiploid pair. In the archegonium of the gametophyte generation c.
Other types of plants also have an alternation of generations but over time in the more advanced plants it is the sporophyte generation that has become dominant. In the antheridia and archegonia of the gametophyte generation b. A In the antheridia and archegonia of the gametophyte generation B In the archegonium of the gametophyte generation C In the spores after being released by the sporophyte D In the sporangium at the time of spore formation.
In ferns it occurs in spore mother ceils found in sporangia. Mosses have diploid and haploid generations. Where does meiosis take place in the moss life cycle.
The process of meiosis occurs in spore mother cells of sporangium for the formation of haploid spores. Fertilized eggs in gametophytes form sporophytes at the site of fertilization.
