Starting with Greek philosophers such as Aristotle and Theophrastus, this species had been mentioned in the herbal literature (in many cases, as a ‘lichen’) long before modern plant taxonomic study was applied ( Lindberg 1877 , Schuster 1966 , Bowman 2016 ). 4. Introduction. Why mitochondria is called as the power house of the cell? These are present at the apex of female branches surrounded by perichaetial leaves. Share Your PDF File Below the epidermis is the cortex. 9. Below the epidermis are a few layers of colourless parenchymatous hypodermis, which surrounds one or two layers of green, chlorophyll-bearing spongy cells. Capsules are abundant with the moss surviving as spore when conditions are not suitable. Single-layered epidermis is the outermost layer, and consists of small chlorophyll-bearing green cells, but mature stems lack chlorophyll. 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.

Seta is very long, cord-like, reddish brown structure, and it held the capsule high. They show alternation of generation i.e. a)      Protonema: Protonema is a prostrate, green, branched filamentous structure. The adult plant consists of gametophores only. Funaria hygrometrica is called “cord moss” because of the twisted seta which is very hygroscopic and untwists when moist. 4. 8. It is circular, cup-shaped lid, present at the top of the capsule.

(A) Apical area of capsule. Innermost region of conducting strand or medulla consists of narrow, thin-walled and vertically elongated cells. That is why, the plant body of Funaria is predominantly gametophyte with sporophyte. Funaria hygrometrica is monoecious and autoecious, i.e., archegonia and antheridia develop on two different branches of the same plant. Primary xylem contains neither true vessels (tracheae) nor wood fibres which characteristic of angiosperms. Its functions are absorption and anchorage.

Anatomy of spear stage capsules of Funaria. It is covered by a layer of epidermis, the continuity of which is broken by many stomata (Figs. It gives rise to erect leafy shoots called gametophores. Mosses share with the Marchantiophyta and Anthocerotophyta a haplodiplobiontic life cycle that marks the shift from the haploid-dominated life cycle of the algal ancestors of embryophytes to the sporophyte-dominated life cycle of vascular plants. Apophysis is the basal, green, photosynthetic region of the capsule. 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.

Spore sac is bounded externally by a few layers of cells, but only one layer is present on its inner side. It is divisible into foot, seta and capsule. Stem Anatomy In many mosses, the stem is anatomically complex, consisting of a differentiated epidermal layer, a cortex, FIGURE 1. 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. With approximately 13 000 species, the Bryophyta compose the second most diverse phylum of land plants. The uppermost lid or cap-like region of the capsule is the operculum (Fig 202), which helps in the dehiscence of capsule and dispersal of spores. With approximately 13 000 species, the Bryophyta compose the second most diverse phylum of land plants. Foot is conical in shape and remains buried in the upper tissue of the gametophore. (A–C) Cross-section of spear sporophyte from apex to seta entirely covered by the calyptra. 7. General Anatomy: It is composed of small pith, a thick vascular cyclinder made up of a ring of separate collateral and open vascular bundles. The gametophytic generation represents the dominant phase in the life cycle of bryophytes. 3. Protonema is short lived, therefore a transitory structure. Each androcyte metamorphoses into a single biflagellate antherozoid. TOS4. Internally, there is no much specialization of cells. Many antheridia in different stages of development are present on male branch. It may also contain chloroplast. The plant body is differentiated into an erect They reproduce by spore formation. 199B). Funaria hygrometrica is the most common species. Operculum remains connected with the capsule by the annulus. The Anatomy of Glacial Ice Loss NASA scientists traverse Antarctica's icy landscape, towing scientific instruments and cold-weather gear with them. 10.

Bryophyta: Funaria - External, Internal Structure and Reproduction, Plant is small about 1-3 cm long, stem is erect and branched. Cut transverse sections of axis and leaf, stain them in safranin, mount in glycerine and study under microscope. Capsule is erect when young but becomes pendant at maturity. 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. That is why, the plant body of Funaria is predominantly gametophyte with sporophyte. They are surrounded by perichaetial leaves. Cut L.S. They are present at the tip of the male branches (Fig. Jacket encloses many androcyte mother cells, each of which divides into two androcytes.
