Spore sac is filled with the spores formed by the reduction division in spore mother cells. In each row there are present 16 teeth. Funaria is a genus of approximately 210 species of moss. LIFE CYCLE OF FUNARIA (Division: Bryophyta, Class: Bryopsida, Order: Funariales, Family: Funariaceae, Genus: Funaria) Occurrence: Funaria is a terrestrial moss which grows as dense green patches, in moist shady conditions such as damp soil, shady banks, damp tree trunks and walls. 1. 202A, 205). • Funaria hygrometrica is the most common species. Below the epidermis is spongy zone of sub- epidermis, the cells of which contain chloroplasts. Caussin C, Fleurat-Lessard P, Bonnemain JL. That is why, the plant body of Funaria is predominantly gametophyte with sporophyte. 2. Life cycle of_funaria 1. 2.

Thallose liverworts, which are branching and ribbonlike, grow commonly on moist soil or damp rocks, while Introduction. Content Guidelines 2. of thallus, stain in safranin, mount in glycerine and study. Tease out the tip portions of certain branches, remove the cluster of leaves to bring out antheridia and archegonia, stain them in safranin, mount in glycerine and study: 1. The gametophytic generation represents the dominant phase in the life cycle of bryophytes. The cells of the wings are large, green, parenchymatous and contain many chloroplasts. (A–C) Cross-section of spear sporophyte from apex to seta entirely covered by the calyptra. Internally, seta is differentiated into thin-walled cells of conducting strands surrounded by many layers of thick-walled cortex and an outermost layer of epidermis (Fig. Single-layered epidermis is the outermost layer, and consists of small chlorophyll-bearing green cells, but mature stems lack chlorophyll. a) Protonema: Protonema is a prostrate, green, branched filamentous structure. Spore sac is bounded externally by a few layers of cells, but only one layer is present on its inner side. The adult plant consists of gametophores only. Its plant body is composed of protonema and gametophore. General morpohological features of mosses.

The rhizoids are multicellular and branched. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. l The adult plant body is foliose, i.e., erect and leafy. Funaria plant is a gametophyte. It surrounds the spore sac. 197B). These are peristomial teeth (Fig. It gives rise to erect leafy shoots called gametophores. (A–C) Cross-section of spear sporophyte from apex to seta entirely covered by the calyptra. HSEB botany notes | Morphology of funaria 12:30:00 AM 0 The plant body of moss plant is foliose (Differentiated into axis and leaves) and gametophyte. [PMC free article] Budke JM, Goffinet B, Jones CS. Share Your Word File Anatomy of spear stage capsules of Funaria. 200). Watch Queue Queue It is differentiated into rhizoids, axis, and leaves. The sporophyte phase is dependent on the gametophyte. 10. 2. They are surrounded by perichaetial leaves. The gametophytic generation represents the dominant phase in the life cycle of bryophytes. The fine structure of the hydroids in the Funaria leaflet is comparable with that fond in other parts of the gametophyte (central strand, Hebant, 1970; leaf traces penetrating the ground tissue, Hebant, 1969) and the sporophyte (central strand, Schulz and Wiencke, 1976) of Funaria as well as of other mosses (d. Hebant, 1974, 1977, 1979). 3. 7. Its plant body is composed of protonema and gametophore. (A–C) Cross-section of spear sporophyte from apex to seta entirely covered by the calyptra. The columella (c) and archesporium (a) are located at the centre of the sporophyte, surrounded by the amphithecium (am), which contains the peristomial layers and epidermis.
