Encyclopedia

Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is today generally limited to the green plants, which form an unranked clade Viridiplantae (Latin for “green plants”). This includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae, and excludes the red and brown algae. Historically, plants formed one of two kingdoms covering all living things that were not animals, and both algae and fungi were treated as plants; however all current definitions of “plant” exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria).

Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although asexual reproduction is also common. — Wikipedia

  • A photosynthetic organism's 'Water World'
    on November 17, 2017 at 7:17 pm

    Following the path of radicals and being able to identify many damaged residues because of incredibly accurate, expeditious and sensitive mass spectrometry, three scientists studied the great granddaddy of all photosynthetic organisms -- a strain of cyanobacteria -- to develop the first experimental map of that organism's water world. […]

  • Drones could help crop management take off,...
    on November 17, 2017 at 7:17 pm

    Initial results of an ongoing study show that aerial imagery produced by multi-spectral sensors as well as less-expensive digital cameras may improve accuracy and efficiency of plant stand assessment in cotton. […]

    on November 17, 2017 at 3:38 pm

    People living in polluted urban areas are far less likely to be admitted to hospital with asthma when there are lots of trees in their neighborhood, a new study has found. […]

    on November 17, 2017 at 3:38 pm

    New research suggests that plant respiration is a larger source of carbon emissions than previously thought, and warns that as the world warms, this may reduce the ability of Earth's land surface to absorb emissions due to fossil fuel burning. […]

  • European forests might not be realizing their...
    on November 17, 2017 at 1:58 pm

    European forest managers can have their cake and eat it, because according to a new study maximizing timber production in a forest does not necessarily have to come at a cost of reduced species diversity or the capacity to regulate climate change by the same forest. However most European forests fall well below their possible maximum levels of these three capacities. […]
