Answer 2

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)
