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. List of 20 Bryophytes (With Diagram) Biology Discussion The mature sporophyte shows a spherical capsule and a bulbous foot connected by a very short neck. The whole sporophyte is covered by calyptra and perichaetial leaves. Capsule shows a jacket of 4 to 6 layers and the spore sac full of spores overarches the dome shaped columella. The upper part of jacket forms an operculum with an annulus. Life cycle sporophyte liverwort bryophyte The long, grey "fingers" that hang down around the sporophyte indicate the perigynium, a fleshy sleeve that initially surrounds and protects the young sporophyte. The diagram is a coloured version of figure 3 in plate 19 of Agnes A Brewster's Botany for Australian Secondary Schools, published in 1929. bio diagram 1 sporophyte Diagram | Quizlet Start studying bio diagram 1 sporophyte. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Difference Between Sporophyte and Gametophyte ... The key difference between sporophyte and gametophyte is that the sporophyte is a diploid structure that participates in asexual reproduction while the gametophyte is a haploid structure that participates in sexual reproduction of plants. Also, sporophyte phase produces haploid spores, while gametophyte phase produces Alternation of Generations: The Gametophyte and Sporophyte ... Alternation of generations diagram ... We can see on our diagram that the sporophyte is made up of similar cells and that they are all diploid, as it is in the 2n section of our diagram. The Difference Between a Sporophyte and ... Sciencing The sporophyte forms from a fertilized egg inside the flask like archegonium and attaches to the gametophyte via a penetrating foot. The sporophyte receives nourishment from the gametophyte. The sporophyte forms a very small stalk called a seta and a single sporangium. A protective covering called a calyptra surrounds this embryonic sporophyte. Life cycle Sporophyte development moss bryophyte Life cycle – Sporophyte development Mosses . Where a seta is present it elongates early, while the spore capsule is still undeveloped, and the elongation is by production of additional cells. In a species with a long seta the growing sporophyte breaks through the enveloping calyptra. Lab 12: Bryophytes : Mosses and Liverworts (and hornworts) • Sporophyte (diploid generation) is attached to and dependent on the gametophyte for the entire life cycle. • The gametophyte is the leafy part. The sprophyte is the spore bearing part. • Used to be one phyllum (Bryophyta). Now three: Bryophyta (mosses), Hepatophyta (liverworts), and Anthoceraphyta (hornworts) Chapter 29 & 30.1 Flashcards | Quizlet In mosses, the sporophyte is the dominant stage of the life cycle; in ferns, the gametophyte is the dominant stage of the life cycle. In both mosses and ferns, moisture is required for sperm to reach the egg. In mosses, the gametophyte is the dominant stage of the life cycle; in ferns, the sporophyte is the dominant stage of the life cycle. Alternation of generations Diagram showing the alternation of generations between a diploid sporophyte (bottom) and a haploid gametophyte (top) 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 haploid sexual and diploid asexual stages. Sporophyte Definition, Function and Examples | Biology ... This diagram shows the alternation of generations between the diploid sporophyte and the haploid gametophyte.. Examples of Sporophyte. Sporophytes are referred to as spore producing plants. However, it is important to take note of the fact that all plants produce spores.
