Liverworts come in two basic types; the leathery, lobed thalloid sheets and the leafy or moss-like gametophytes. Only the edges of liverwort leaves have lobes or points. The leaves are aligned in two rows along the stem.
Moss leaf edges may be serrated but are never lobed. The majority are smooth edged, all the same size, and are arranged in a spiral along the stem
Only moss have phyllids (leaf-like flanges) with cells along the midline that have a facilitated internal osmosis of water: prevascular xylem-like hydroid cells and the phloem-like leptoid cells. Liverworts lack these cell types.

How is the gametophyte of marchantia sp different from the gametophyte of funaria sp?
the gametophyte of marchantia sp is thalloid and dorsi-ventrally flattened while that of funaria sp is differentiated into leaf-like, stem-like and root-like structures
Why polytrichum sp are not widespread on land?

Explain the importance of gemma cups to Marchantia sp?
Liverworts can also reproduce asexually by means of special structures called gemmae cups. These little cups can be easily seen on the surface of the plant. Each gemma cup contains a number of tiny plantlets called gemmae, and a single drop of water will disperse them. These little vegetative "clones" will then grow into a new gametophyte.
What is the comparison between spores and leaves of lycopodium sp. and selaginella sp.?
Lycopodium is Isophyllous,Homosporous.It has monocious gametophyte and do not have rhizophores.But Selaginella is Dimorphism, heterosporous.It has dioecious gmetophyte and rhizophores
Compare the spores and leaves of lycopodium sp and selaginella sp?
Lycopodium has only one size of spores said to homosporous while Selaginella has both a microspore that grows into the male gametophyte and macrospores that produces female gametophytes. Selaginella has ligules at the base of each microphyl
