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.
Xylem (blue) transports water and minerals from the roots upwards. Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of the xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
Tracheophyta o Tracheobionta es un taxón que abarca a las plantas vasculares o traqueofitas. Son organismos formados por células vegetales, que poseen un ciclo de vida en el que se alternan las generaciones gametofítica y esporofítica, siendo esta última la fase dominante (sobre quién actúa más presión de selección natural ); cuya ...
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 ...
The Marchantiophyta ( / mɑːrˌkæntiˈɒfətə, - oʊˈfaɪtə / ⓘ) are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte -dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are ...
Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude the fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land ...
