Angiosperms are a clade of seed plants. They produce seeds for sexual reproduction; however, unlike their sister clade gymnosperms, angiosperm seeds are enclosed in a structure known as a fruit for protection. In addition, they often produce and utilize flowers for protection and attraction in pollination. As such, angiosperms are commonly known as flowering plants and are some of the most prominent and most successful plants found in modern day.

Angiosperms can be divided into two clades based on a variety of characteristics; they are particularly named for the number of cotyledons present during development. This list also includes the arrangement of the veins produced by their vascular tissue, the arrangement of their vascular bundles, the categorization of their root systems, and the pattern number of organs developed in the plant flower. These clades are the monocot and eudicot (formerly dicot) clades.

Angiosperms include both herbs and woody plants. More popular angiosperms include fruits, vegetables, and common β€œflowers”.
