Phloem Tissue and Sieve Elements in Algae, Mosses and Ferns

摘要: During the phylogenetic development of plants from unicellular aquatic algae to highly specialized seed plants, acquisition a particular vascular tissue has become one major bases for life on land. Parallel organs like stem, leaves, and roots, differentiation specific tissues epidermis, rhizodermis, sclerenchyma, phloem xylem adjust plant altered surroundings. As we will see, most tissues, tissue, were subject changes during evolution primitive more advanced land plants. Although there was need cells in long-distance transport larger brown algae, e.g. giant kelps, organized food translocation, closely associated those facilitating distribution water, initiated only bryophytes. In three parts follow review structure respective and/or mosses, ferns.
