These serve for anchorage to the substrate and water uptake, but they are no true roots. Annulus is ring like cell dycle operculum and Theca. Classification of the mosses Mosses are the most primitive land plants.

All mosses used to be regrouped under the phylum Bryophyta. In other projects Wikispecies. There is formation of different rings by anticlinal and periclinal divisions. The female shoot arise from the base of the male shoot and called as archegonial branch or archegoniophore.

These cells are now commonly called as hydroids. It lies between the apophysis and operculum. The first wall divides the segment into two cells of unequal size. Depth is visible with red-green glasses, preferably with red right. Articles lacking in-text citations from March All oife lacking in-text citations Articles with ‘species’ microformats.

Funaria – Wikipedia

Funaria euryloma Dixon Funaria eurystoma Mitt. Life Cycle of Cycas: In funaria root like structures called Rhizoids are present. Gunaria the capsule, spore-producing cells undergo meiosis to form haploid spores. Funaria microstoma Bruch ex Schimp. Under favourable conditions sufficient moisture spores germinate. The amphithecium divides by periclinal division to form two concentric layers. The basal cell divides and re-divides to form the stalk of the archegonium.

It consists two to three layers of loosely arranged chlorophyllous cells. Cyfle like perigonial leaves serve as splash cup from which rain drops disperse antheroziods to some distance rain drops falling on the archegonial cluster situated at lower level. Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top. Each spore is spherical Fig.

Mosses (Overview)

The spores are dispersed by the wind and germinate to filamentous protonemata. Accidentally, or death of intercalary, segment sometime causes fragmentation of primary protonema, each fragment can give rise to leafy gametophore. DVD-Video, in German, but the images are self-explaining Mosses are simple, green little land plants, which are considered as “lower plants”. But the ‘leafy’ part of the gametophyte lacks stomata.

Rhizoids arise from the base of the axis. The uptake of water and nutrients can occur over the entire thallus.

Each androcyte mother cell divides further and form two androcytes. If you wish to download it, please recommend it to your friends in any social system.

Hornworts The Hornworts resemble the Liverworts, but they look more like real plantlets. It is funnaria phototropic and produce buds which later develop into leafy gametophores. Water is essential for fertilization. Each ring of peristome possesses 16 ffunaria. The life cycles of all mosses Liverworts, Hornworts and Bryophytes are in principle similar. The tip of male shoot has a convex disc or receptacle on which a cluster of club-shaped antheridia intermingled with like capitates paraphysis arises.

Embryo develops into sporophyte. This develops lateral bud which grows into leafy gametophore.

Antheridium develops from a single superficial slightly projected cell. Each archegonium has a stalk, flask-shaped venter and a neck. Archesporium is endothecial in origin.
