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 ...
Wildlife of Australia. The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity ...
Plant - Vascular, Photosynthesis, Reproduction: Vascular plants (tracheophytes) possess supporting and water-conducting tissue called xylem and food-conducting tissue called phloem; they also have true stems, leaves, and roots. Lycophytes (class Lycopodiopsida) are nonseed plants represented by three living orders, the principal genera being club mosses, spike mosses, and quillworts.
Plantas vasculares, também designadas por traqueófitas e por plantas superiores, é um grande agrupamento de plantas constituído pelas plantas terrestres que apresentam tecidos especializados destinados ao transporte dos solutos que alimentam as suas células. Com excepção das plantas avasculares, estas estruturas estão presentes em todos os grupos extantes de plantas, nomeadamente nas ...
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 ...
Herbaceous plant. Lysimachia latifolia (broadleaf starflower) is a perennial herbaceous plant of the ground layer of forests in western North America. Herbaceous plants are vascular plants that have no persistent woody stems above ground. [1] [2] This broad category of plants includes many perennials, and nearly all annuals and biennials.
Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta,:251 Tracheobionta and Equisetopsida sensu lato. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used ...
