Lycopodiopsida is a class of vascular plants also known as lycopods or lycophytes. Members of the class are also called clubmosses, firmosses, spikemosses and quillworts. They have dichotomously branching stems bearing simple leaves called microphylls and reproduce by means of spores borne in sporangia on the sides of the stems at the bases of ...
Non-vascular plants is a general term for those plants without a vascular system ( xylem and phloem ). Although non-vascular plants do not have these tissues, some of them have other tissues for internal transport of water . Nonvascular plants have no roots, stems, or leaves. These structures always have some vascular tissue.
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 ...
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.
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 ...
