Dispersed tubular microfossils that can be traced to the early Silurian (440 Ma; Pratt et al., 1978; Burgess and Edwards, 1991) are thought to derive from the same type of plants (Edwards et al., 1995), wherein they would have performed the same function.

Improved knowledge of the intimate structure and developmental regulation of transporting tissues across the entire taxonomic breadth of extant plant lineages, combined with more comprehensive documentation of the fossil record of transporting tissues, is required for a full understanding of the evolutionary trajectory of transporting tissues. (B) The presence of several known polymers and the abundance within different land plant taxa. The members of one of the chief living families, Lycopodiaceae, are homosporous (with just one kind of spore). 45c, 1318 (1989). Lycophylls arise from an intercalary meristem (a region of active division occurring in the stem at the base of a leaf), whereas euphylls grow from an apical meristem.

Stout, S. C., Clark, G. B., Archer-Evans, S. & Roux, S. J. Important for this consideration is to acknowledge both differences and evolutionary graduality between tracheophyte clades: from lycophytes and monocots to angiosperms, in terms of their transporting tissues (Spicer and Groover, 2010; Spencer et al., 2021). Many of the ancient lycophytes, such as Lepidodendron, were treelike plants that often exceeded 30 metres (100 feet) in height.

The importance of these WCCs that contain lignin is reflected by the naming of an entire clade after them, which contains 95% of all extant plant species: the tracheophytes or vascular plants. Conductive tissue is widely spread among different bryophytes, most of which are seen in liverwort and moss species (Figure2). It includes diverse true ferns. The genome-wide dynamics of purging during selfing in maize. Similar to sieve elements, leptoids have some form of sieve areas with enlarged plasmodesmatal openings (Scheirer, 1990).
