Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta ( / braɪˈɒfətə /, [3] / ˌbraɪ.əˈfaɪtə /) sensu stricto. Bryophyta ( sensu lato, Schimp. 1879 [4]) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. [5] Mosses typically form dense green clumps or mats ...
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees , shrubs and vines , and most aquatic plants .

Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers ), and angiosperms ( flowering plants ). Scientific names for the group include Tracheophyta, [8] [4] : 251 Tracheobionta [9] and Equisetopsida sensu lato. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term ...
Plant stem. This above-ground stem of Polygonum has lost its leaves, but is producing adventitious roots from the nodes. A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and ...
Pteridopsida Ritgen 1828. The ferns ( Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the ...
Vascular plants transport sucrose in a special tissue called the phloem. The phloem and xylem are parallel to each other, but the transport of materials is usually in opposite directions. Within the leaf these vascular systems branch (ramify) to form veins which supply as much of the leaf as possible, ensuring that cells carrying out photosynthesis are close to the transportation system.
