$\longrightarrow$The leaf like simple lobes are present. Ther are spirally arranged.

$\longrightarrow$The rizouds are multicellular branched

$\longrightarrow$They are gametophytic plants. The axis may be branched or unbranched

$\longrightarrow$Sex organs are usually born in groups They develop from superficial cell and usually show definute apical cell

$\longrightarrow$They are usually differentiated into foot ,seta and capsule.

Mosses

The monera comes under kingdom plantae. These are widely distributed over the artic and antarctic. They also grows in desert ,streams , damp aoil ajd tree trunk.

☣☣The mosses are the plants which are inhabit on moist brick walls and they form a thick layer as a mat on forest floor as well as on the shaded trees.

☣☣Mosses also require water as a medium for completing their life cycle.

☣☣The gametophytic plant body has short stem and large number of whorls of leaves surrounding it.

☣☣There is alternation of generation between the haploid gametophytic phase and the diploid sporophytic phase.

☣☣The gametophytic phase produces the haploid gametes.

☣☣The sperm is produced inside the antheridia and egg is produced inside the archegonia.

☣☣Fertilization occurs resulting in the formation of the zygote which undergoes mitosis and forms the sporophyte.

☣☣The gametophytic plant body anchor to the substratum by means of rhizoids.

☣☣The sporophyte is attached to the gametophytic plant body. It lacks chlorophyll it depends on the photosynthetic gametophyte.

☣☣The sporophyte consists of the foot, stalk and a capsule.

☣☣By meiotic division the haploid spores are produced inside the capsule.

☣☣As the spores matures the lid of the capsule get opened.
