Flowering plants are also known as angiosperms. Angiosperms are the largest group and most species-rich phylum of plants on Earth.

Our most familiar plants like pea, mango, coconut, wheat and rice come under the group called Angiosperms. Their seeds are always enclosed in the fruit. A fruit is a mature ovary.

Angiosperms have flowers and bear seeds enclosed in a protective covering called a fruit. The angiosperms are divided into two groups; Dicotyledons and Monocotyledons. Monocot plants seeds have single cotyledon while dicot plants seeds have two cotyledons.

Gymnosperms

Angiosperms

Seeds naked as not enclosed in ovary.

Seeds enclosed in fruit (a mature ovary)

Bears cones where spores (gametes) develop.

Bears flowers where reproductive spores (gametes) develop.

Xylem vessels usually absent.

Xylem has both vessels as well as tracheids.

Has haploid tissue (endosperm produced before fertilization)

Has triploid tissue (endosperm produced during triple fusion).

Leaves are flat in shape.

Leaves are scale like and needle-like in shape.

Examples are Pinus, Cycas and Cedrus trees.
