Bryophytes

While grasses and flowers resolve this problem with the help of the plant hormone gibberellin, bryophytes lack the genes to do this.

It is the only site of such high altitude with bryophytes preserved over thousands of years.

Bryophytes are present in most of the major vegetation communities including several soil and moss-inhabiting species.

Bryophytes Bryophyte is a traditional name used to refer to all embryophytes (land plants) that do not have true vascular tissue and are therefore called "non-vascular plants".

It is characterised by Azorella selago cushions interspersed with bryophytes, small vascular species and bare ground with 20–75% cover, and found mainly at altitudes between 30–70m asl.

Some bryophytes do have specialised tissues for the transport of water; however, since these do not contain lignin, they are not considered true vascular tissue.

The bryophytes lack phloem, but moss sporophytes have a simpler tissue with analogous function known as the leptome.

The bryophytes lack true xylem cells, but their sporophytes have a water-conducting tissue known as the hydrome that is composed of elongated cells of simpler construction.
