A division of the plant kingdom that includes all flowering plants, i.e. vascular plants in which double fertilization occurs resulting in development of fruit containing seeds. Divided into two major groups, monocotyledons and dicotyledons
Any plant that is a member of the class Angiospermae, in which the seeds are enclosed in an ovary. Each member of the class is either a monocotyledon (grasses, tulips) or a dicotyledon (apple, primrose).
Belonging to the class of plants having seeds enclosed in an overlay. Within this class, the subclass dicotyledons includes all hardwood trees. A.W.I. - Architectural Woodwork Institute 1952 Isaac Newton Square Reston, VA 20190
(pronounced AN-jee-oh-sperm) Angiosperms (meaning "covered seed") are flowering plants. They produce seeds enclosed in fruit (an ovary). They are the dominant type of plant today; there are over 250,000 species. Their flowers are used in reproduction. Angiosperms evolved about 145 million years ago, during the late Jurassic period, and were eaten by dinosaurs. They became the dominant land plants about 100 million years ago (edging out conifers, a type of gymnosperm). Angiosperms are divided into the monocots (like corn) and dicots (like beans).
A plant that has true flowers and bears its seeds in fruits. In temperate zones, many angiosperms are deciduous trees, while in tropical zones, many are evergreen trees. Examples include oaks, willows, maples and birches.
The 'flowering plants', the most recent group of plants to evolve. These plants have reduced their alternation of generations to the production of pollen (male gametophyte) and ovules (female gametophyte retained by the parent plant). Pollen is released and is carried to the female either by the wind or a pollinator such as an insect. Flowers have evolved to aid in wind dispersal or to attract pollinators to collect and distribute pollen. Most of the plants we see around are angiosperms; their reproduction and adaptability have made them a huge success.
A plant whose ovules are enclosed in an ovary; a flowering plant. cf. Gymnosperm nhydrous Without water, especially water of crystallization. nhydrous Ammonia A nitrogen fertiliser that is applied as a pressurised liquid into the soil where it combines with water to release the nitrogen. It needs special equipment and care in handling. See http://www.extension.umn.edu/distribution/cropsystems/DC2326.html
