Bryophytes, Pteridophytes, and Gymnosperms Quiz

Differences between Gymnosperms and Angiosperms

• Gymnosperms have seeds that are naked, meaning they are exposed and not enclosed in ovaries like angiosperms
• Angiosperms, on the other hand, have seeds that are enclosed in ovaries

Characteristics of Gymnosperms

• One characteristic of gymnosperms is that they produce seeds that are exposed on the surface of scales or leaves

Evolutionary History of Gymnosperms

• In warmer areas, angiosperms eventually replaced gymnosperms as the dominant plant form
• Gymnosperms were once the dominant plant form, but they were outcompeted by angiosperms in warmer areas

Present-Day Distribution of Gymnosperms

• Today, gymnosperms are primarily found in cooler, temperate, and subarctic regions of the world

Evolutionary History of Gymnosperms compared to Angiosperms

• Gymnosperms evolved earlier than angiosperms, with fossil evidence showing that gymnosperms date back to the Paleozoic Era, around 380 million years ago
• Angiosperms, on the other hand, did not evolve until the Cretaceous Period, around 130 million years ago

Examples of Gymnosperms

• Examples of gymnosperms include pines, spruces, and firs
