ADVERTISEMENTS: In this article we will discuss about the anatomy of funaria. 6. The rhizoids present in this species are multi- cellular andbranched.Theyhaveobliquesepta. Midrib is several-celled thick and contains many thin-walled cells of conducting strand. Funaria hygrometrica is called “cord moss” because of the twisted seta which is very hygroscopic and untwists when moist. Share Your PPT File. 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.

One of its species F. hygrometrica, is cosmopolitan and best known. Capsule wall, in this region is bounded by a layer of epidermis with very few or no stomata. Axis: ADVERTISEMENTS: 1. Internally, there is no much specialization of cells. the gametophytic stage alternates with the sporophytic stage. Questions from Haryana PMT 2007 1. It is circular, cup-shaped lid, present at the top of the capsule. 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. 197B). Anatomy of spear stage capsules of Funaria. Sunday, October 30, 2016. Peristomial teeth become visible. The adult plant consists of gametophores only. 4. Question 2. With approximately 13 000 species, the Bryophyta compose the second most diverse phylum of land plants. They show alternation of generation i.e. Liverwort, (division Marchantiophyta), any of more than 9,000 species of small nonvascular spore-producing plants. Introduction. Antheridia remain surrounded by many perichaetial leaves. There is no xylem or phloem. In this article we will discuss about the morphology of funaria with the help of a suitable diagram. These are known as paraphyses. With approximately 13 000 species, the Bryophyta compose the second most diverse phylum of land plants. Annals of Botany. The name is derived from the Latin word “funis”, meaning a rope. The rhizoids are septae. They are surrounded by perichaetial leaves. 4.

The gametophytic body has upright , slender, and stem like axis which is about 1.3 or 1-3 cm long. It has 1-3 cm height. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? The sporophyte phase is dependent on the gametophyte. It is differentiated into rhizoids, axis, and leaves. 5. Neck consists of six vertical rows of cells, and encloses 6 to 8 neck canal cells, a ventral canal cell and an egg. 2011; 107:1279–1286. 8. 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. 7. They help in spore dispersal on opening out in dry conditions. Primary xylem contains neither true vessels (tracheae) nor wood fibres which characteristic of angiosperms. Seta is very long, cord-like, reddish brown structure, and it held the capsule high. In gymnosperms, the pollen chamber represents: (1) a cell in the pollen grain in which the sperms are formed (2) a cavity in the ovule in which pollen grains are stored after pollination 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.

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. Funaria hygrometrica is the most common species. 8. a) Protonema: Protonema is a prostrate, green, branched filamentous structure.
