The Angiosperms=Success story
Division Magnoliophyta
General information about the Angiosperms. . .
They are the most successful of all plants
They possess specialized water-conducting cells called vessel elements in the xylem tissue
They possess efficient sugar-conducting cells called sieve tube members in their phloem
They reproduce sexually - producing flowers, fruits, and seeds
The double fertilization that occurs during sexual reproduction is unique
They are used by humans extensively as a source for food, grains, vegetables, fruit,
hardwoods, fibers, medicines, etc.

Monocots (Class Liliopsida) & Dicots (Class Magnoliopsida) are the two classes of Angiosperms
· Monocots include palms, grasses, orchids, and lilies
· Dicots include oaks, roses, cacti, sunflowers, and strawberries


===============
The botanical term "Angiosperm", from the ancient Greek αγγειον (receptacle) and σπερμα (seed), was coined in the form Angiospermae by Paul Hermann in 1690, as the name of that one of his primary divisions of the plant kingdom, which included flowering plants possessing seeds enclosed in capsules, in contradistinction to his Gymnospermae, or flowering plants with achenial or schizo-carpic fruits, the whole fruit or each of its pieces being here regarded as a seed and naked. The term and its antonym were maintained by Carolus Linnaeus with the same sense, but with restricted application, in the names of the orders of his class Didynamia. Its use with any approach to its modern scope only became possible after Robert Brown had established in 1827 the existence of truly naked ovules in the Cycadeae and Coniferae, entitling them to be correctly called Gymnosperms. From that time onwards, so long as these Gymnosperms were, as was usual, reckoned as dicotyledonous flowering plants, the term Angiosperm was used antithetically by botanical writers, but with varying limitation, as a group-name for other dicotyledonous plants.
