The outermost layer is thick walled and called epidermis.
Vegetative propagation is a method by which a ufnaria of the gametophyte separate or specialized to form a new individual. The inner ring of peristomial teeth do not show hygroscopic movement.

It bears large number of reddish brown or orange antheridia in different stages of development. Soon, the zygote secretes a cell wall and becomes the oospore.
The cells contain many large and prominent chloroplasts Fig. It is bounded by the single layered epidermis which is interrupted by stomata. Chloronemal branches produce several buds, each of which develop into a leafy gametophore. They are the common moss, also known as cord moss or green moss.
Archegonial initial divides by transverse division to form the basal cell or stalk cell and a terminal cell. From these two group of cells the further development takes place. Similarly, the hypo basal cell differentiates an apical cell Fig.
Venter canal cell is situated just below the neck canal cells. The female branch arises from the base of the male branch. Small cell is called jacket initial Fig. These cells are now commonly called as hydroids.

Many antherozoids enter the archegonial neck because of chemical response but only one of them fuses with the egg to form the zygote. The outer primary cover cell functions as aplical cell with four cutting faces three lateral and one basal.

They help in anchorage and absorption. It is called neck of the funaira. It is present below the epidermis. Male reproductive structure is known as antheridium and female as archegonium. Fig Table Fig Origin of land plants about mya Origin of vascular plants about mya Origin of extant seed plants.
It is the central part of the theca region. Simultaneously when the apical cell is dividing, the third or fourth segments below the apical cell, starts dividing from base, upwards by diagonal vertical walls. The Kingdom of Plants: Each germ tube is multicellular, green fknaria oblique septa.
Each basal cell adds to neck canal cell. The peripheral cells divide anticlinally to form a single layered wall of venter which later becomes two layered. They are slender, branched, and multicellular and have oblique septa.
