The primary difference between gymnosperms and angiosperms is that angiosperms reproduce through flowers.
Flowers are modified shoots that have a series of modified attachments such as leaves and have ovaries surrounded and protected by a female reproductive formation, carpel, or pistil.
Among other features, the closed position of seeds give flowering plants a competitive advantage and enable them to dominate existing vegetation.
2. Gymnosperms:
Cone gymnosperms are one of the largest and oldest living organisms in the world.
Today gymnosperms are of great economic value as the main source of wood products, pulpwood, turpentine, and resin.
3. Pteridophyte:
Pteridophyte is a vascular plant that disperses spores.
Because Pteridophytes produce neither flowers nor seeds, they are sometimes referred to as cryptogamous, meaning that their means of reproduction are hidden.
