Here's a breakdown:

Angiosperms

* Definition: Flowering plants, the most diverse group of plants. They produce flowers, which contain the reproductive organs (stamens and pistils).

* Seeds: Enclosed within a fruit.

* Examples: Apples, oranges, roses, tulips, sunflowers, corn, wheat, rice.

Gymnosperms

* Definition: Non-flowering plants with seeds exposed on the surface of cones.

* Seeds: Typically found in cones, not enclosed within a fruit.

* Examples: Conifers (pines, spruces, firs, cedars), cycads, ginkgoes.

Other plants that don't produce seeds:

* Ferns: Reproduce through spores.

* Mosses: Reproduce through spores.

* Liverworts: Reproduce through spores.

* Algae: Reproduce through spores or by dividing into two identical halves.
