Angiosperm is a term that is commonly used in the field of botany. It is a term that refers to a particular type of flowering plant. These plants are characterized by their ability to produce flowers and fruits. The term angiosperm is derived from the Greek words “angeion” which means vessel and “sperma” which means seed.
Definitions
Angiosperms are a group of plants that produce flowers and fruits. They are characterized by the presence of a protective covering around the seed, which is known as the ovary. This ovary develops into a fruit after fertilization.
Origin
