Marchantia polymorpha
Specification: 4:1,10:1，20:1,30:1.50:1
Fuction : Marchantia polymorpha is the best characterised of the liverwort. It is a thalloid liverwort, growing as flat sheet-like tissues which possess distinct upper and lower surfaces. The lower surface of the plant has specialised root-like cells, or rhizoids. The body of the thallus contains oil bodies, present as scattered differentiated cells. This is characteristic of the liverwort group. The upper surface has a modular structure, with repeated formation of units that form primitive cell complexes adapted for photosynthesis and gas exchange. Each unit is marked by a single, permanently open central pore. The liverworts have less efficient systems for water transport and retention than higher plants, and can show marked tolerance to desiccation.
