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). The Angiosperms division is composed of two classes, monocotyledons and dicotyledons.
(flowering plants) a class of vascular plants, all characteristically bearing seeds within enclosing carpellary systems (eg. oaks and eucalypts).
The flowering plants. Plants that produce flowers in which the egg cells (ovules) are covered by a tissue called the ovary. The ovules develop into seeds and the ovary into a covering called the fruit.
Flowering, fruit-producing plants. ~ See Also: Flower, Fruit, Gymnospenns.
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).
Flowering plants. First appearing at least 110 million years ago from an unknown gymnosperm ancestor, flowering planbts have risen to dominance in most of the world's floras. The male gametophyte is 2-3 cells contained within a pollen grain; the female gametophyte is usually eight cells contained within an ovule which is retaind on the sporophyte phase of the plant's life cycle.
Flowering plants (cf. Gymnosperms)
Angiosperms are flowering plants that produce seeds enclosed in fruit. They are the dominant type of plant today; there are over 250,000 species. Their flowers are used in reproduction. Angiosperms evolved 125 million years ago and became the dominant plants about 100 million years ago. Angiosperms are divided into the monocots (like corn) and dicots (like beans).
Another name for flowering plants, plants which make their seeds in flowers.
The collective name for flowering plants which evolved in the Late Jurassic period.
