Angiosperms - Metabolism
Research News and Information
Definition of 'Angiosperms'Any member of the more than 250,000 species of flowering plants. Angiosperms are often differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida). Common names: Angiosperms; Magnoliophyta |

Identification of Carboniferous (320 million years old) class Ic amber.
30 Sep 2009 
The presence of amber, the fossil form of the resins produced by many types of higher plants, has been reported from many localities in Mesozoic and Cenozoic rocks. We have found Class I (polylabdanoid) amber in Carboniferous sediments dating to ... Read more...
30 Jul 2009 Biological nitrogen fixation (BNF) is the major nitrogen (N) input in many terrestrial ecosystems, yet we know little about the mechanisms and feedbacks that control this process in natural ecosystems. We here examine BNF in four taxonomically and ... Read more...
Field note: irrigation of tree stands with groundwater containing 1,4-dioxane.
29 Jun 2009 Coniferous and deciduous tree stands totaling 14 ha were recently planted on a closed landfill, and when mature, the stands are expected to be part of a natural treatment system for recovered groundwater. The trees would be irrigated at the rate of ... Read more...
