Diagram of moss sporophyte

A sporophyte (/ s p ɔː r oʊ ˌ f aɪ t /) is the diploid multicellular stage in the life cycle of a plant or alga.It develops from the zygote produced when a haploid egg cell is fertilized by a

haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent.All land plants, and most multicellular algae, have life cycles in which a multicellular Once the cells have divided and created a multicellular structure, it is now called a gametophyte. We can see on our diagram that the gametophyte contains many of the same cells that are all haploid. Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct sexual haploid and asexual diploid stages. In these groups, a multicellular gametophyte, which is haploid with n chromosomes, alternates with a multicellular sporophyte, which is diploid with 2n chromosomes Plant: Plant, any multicellular eukaryotic, usually photosynthetic life-form in the kingdom Plantae. There are an estimated 390,900 diffferent

species of plants known to science. Learn more about the plant kingdom, including the life and evolutionary histories and physical characteristics of the major plant … Among the liverworts it has been demonstrated that small fragments of the stalk of the sporophyte are capable of regenerating diploid

gametophytes.In the mosses, both haploid and diploid apospory have been experimentally evoked.As in the liverworts, injury and regeneration of fragments of the sporophytic seta result in diploid gametophytes. By contrast, fragments of moss leaves, stems, and The Carpel The diagram below shows the structure of a typical angiosperm carpel.The ovary is the main body of the carpel and contains the ovule.The style is an extension of the ovary wall that holds aloft the stigma, which is a surface that is sticky to pollen and acts to receive and trap pollen grains.
