WebJun 6, 2024 · Setaphytes – a bryophyte lineage consisting of mosses and liverworts. Sporophyte – the diploid multicellular generation of land plants. Tracheophytes – vascular plants including lycophytes, ferns, gymnosperms and angiosperms.
WebPlants as we understand them today fall into two major groups: the Bryophyta, which lack a lignified cell wall and hence are unable to grow upwards more than a few centimetres; and the Tracheophyta, which have a lignified cell wall and may become tall trees (e.g. Sequoia sempervirens) over 100 m in height ( Table 1.2 ). WebAll bryophytes have two things in common – they are terrestrial and nonvascular. But what does this mean? To put bryophytes in perspective, they constitute one of three groups that all plants fall into including tracheophytes, thallophytes, and bryophytes. Tracheophytes include vascular plants that have lignin and vascular tissue.
