What is an angiosperm

It is a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.

Angiosperms (a plant whose ovules are enclosed in an ovary) are commonly referred to as "flowering plants", as opposed to gymnosperms, or "cone bearing plants."

Angiosperms form a phylum, the phylum Anthophyta. Angiosperms are also called anthophytes or magnoliophytes. The sporophyte is dominant and the gametophyte is the most reduced of all plants. There are so far more than 300,000 far named angiosperms. Angiosperms evolved in the Cretaceous. Many have close-bound mutualisms with pollinating insects.

Angiosperms are divided into monocotyledons and eudicotyledons (dicotyledons)

Why are vestigial structures not removed by natural selection

Vestigial structures do not harm the organism. Nature selects against only harmful traits.

Why are archaea in a different domain from bacteria

They are thought to have separate paths of evolutionary development.

They developed along different evolutionary paths.

They had independent evolutionary development.
