ANGIOSPERMS - FIRST PLANTS WITH FLOWERS
We asked it before. What would give you an advantage if you were a plant? You have a vascular system to transport nutrients. You have seeds for reproduction that allow your babies to spread out in new areas.
Angiosperms are the flowering plants (today the most abundant and diverse plants on earth).
Most are terrestrial and all lack locomotion. This poses several problems.
angiosperm -- n. A group of plants that produce seeds enclosed within an ovary, which may mature into a fruit; flowering plants.
anther -- The pollen producing tip of a stamen; part of a flower. More info?
Angiosperm: The most recently evolved and the largest group of plants whose reproductive organs are in their flowers (flowering plants).

angiosperms 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.
Angiosperm Life Cycle
Flowering plants also exhibit the typical plant alternation of generations, shown in Figure 11.

[edit] Angiosperms
It is thought that flowering plants evolved from a common hermaphrodite ancestor, and that dioecy evolved from hermaphroditism.
Angiosperms
- 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.

angiosperm The group of plants characterized by having flowers as their sexual reproductive structures.
Angiosperms evolved from gymnosperms, their closest relatives are Gnetae. Two key adaptations allowed them to displace gymnosperms as the dominant fauna -- fruits and flowers.
The angiosperms are the flowering plants. The flowers are the organs of sexual reproduction where the seeds are produced.
Most exam boards only require knowledge about reproduction in Angiosperms - the flowering plants.

As an aid in identifying other conserved regions of angiosperm CENP-Cs, we developed gene models for full-length Cenpc cDNAs by aligning them with available genomic sequences (Additional data file 1).
Xylem tissue is a feature of higher vascular plants (Filicinophyta, Coniferophyta, and Angiospermaphyta). It developed as plants became less dependent on water and lived in drier environments.
Pollination
Transfer of pollen from the anther to the stigma in angiosperms or from the microsporangium to the micropyle in gymnosperms.
Cf. autogamy.

Xylan is a complex plant polymer that represents the most abundant noncellulosic polysaccharide in angiosperms, where it accounts for 20 to 30% of the dry weight of wood tissues.
By the Carboniferous Period, about 355 million years ago, most of the Earth was covered by forests of primitive vascular plants, such as lycopods (scale trees) and gymnosperms (pine trees, ginkgos). Angiosperms, the flowering plants, ...
