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.
s 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 gametophytes are the most reduced of all plants, consisting of only a few cells.
In angiosperms, the sporophyte produces a unique reproductive structure, the flower.

Angiosperm: The most recently evolved and the largest group of plants whose reproductive organs are in their flowers (flowering plants).

s 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.
(an-jee-o-sperms) [Gk. angeion, vessel + sperma, seed]
A flowering plant, which forms seeds inside a protective chamber called an ovary.
angiosperms /ANJ-ee-Å¨-sperms/ Flowering plants; one of the major categories of the Plant Kingdom. Unlike gymnosperms, angiosperms form their seeds within protective capsules called ovaries. COMPARISON OF GYMNOSPERM WITH ANGIOSPERM ...
The seeds of s are somewhat different from those of gymnosperms (see Plant Classification, s.
It is thought that flowering plants evolved from a common hermaphrodite ancestor, and that dioecy evolved from hermaphroditism.
- s 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 plants evolve flowers, structures that attract insects and other animals to spread pollen. The evolution of the angiosperms cause a major burst of animal evolution.

Angiospermophyta the plant phylum which contains the flowering plants.
Animalia the kingdom containing animals.
Annelida the animal phylum containing earthworms and leeches.
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 s are the flowering plants. The flowers are the organs of sexual reproduction where the seeds are produced.

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, ...
As an aid in identifying other conserved regions of CENP-Cs, we developed gene models for full-length Cenpc cDNAs by aligning them with available genomic sequences (Additional data file 1).
Now flowers is something developed by the kind of plant called the angiosperms or simply flowering plants. What flowers do, is they set one of the challenges that plants have when they're engaging in sexual reproduction.
Xylem tissue is a feature of higher vascular plants (Filicinophyta, Coniferophyta, and aphyta). It developed as plants became less dependent on water and lived in drier environments.
endosperm the female tissue that encloses the seed within the angiosperms.
entropy the degree of disorder or randomness of a system.
environmental fitness an individual's ability to adapt to an environment and reproduce.
Transfer of pollen from the anther to the stigma in s or from the microsporangium to the micropyle in gymnosperms.
Transfer of pollen from the anther to the stigma in angiosperms or from the microsporangium to the micropyle in gymnosperms.
Tertiary: The first period of the Cenozoic Era which began about 65 million years and lasted to 1.6 million years before the present, marked by formation of high mountains, the dominance of mammals on land, and s superseding gymnosperms ...
