Aquatic plants are plants that have adapted to living in aquatic environments ( saltwater or freshwater ). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating.
Plant morphology treats both the vegetative structures of plants, as well as the reproductive structures. The vegetative (somatic) structures of vascular plants include two major organ systems: (1) a shoot system, composed of stems and leaves, and (2) a root system. These two systems are common to nearly all vascular plants, and provide a ...
The lycopods, or club mosses, are the main plants in the Carboniferous rain forests. They were only partly eaten by insects and other life-forms. Mostly they formed swamplands which in the course of time became coal measures. In fact most of the coal from the Carboniferous period comes from these swamplands. [9]
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 ...
Equisetum fluviatile – a broken stem with the central hollow exposed. The stems readily pull apart at the joints, and both fertile and sterile stems look alike. [citation needed] The water horsetail is most often confused with the marsh horsetail E. palustre, which has rougher stems with fewer (4–8) stem ridges with a smaller hollow in the ...
The earliest land plants did not have vascular systems for transport of water and nutrients either. Aglaophyton, a rootless vascular plant known from Devonian fossils in the Rhynie chert was the first land plant discovered to have had a symbiotic relationship with fungi which formed arbuscular mycorrhizas, literally "tree-like fungal roots", in ...
