Question

Which of the following traits are unique to angiosperms and absent in the other plant groups?

Answer 1

Answer options:

• fruit
• pollen
• flower
• seed
• spore

Answer:

flower

fruit

Explanation:

Angiosperms include all flowering plants. Therefore, all plants in this group have flowers, whereas other groups do not.

Both angiosperms and gymnosperms have seeds, but angiosperms are defined by the fact that their seeds develop within a surrounding layer of usually the flower. Both angiosperms and gymnosperms also have pollen - likely an adaptation to living on dry land. Many plants produce spores, not just angiosperms.

Angiosperms produce fruit, unlike other plant groups. This fruit is the protective layer that encases their seeds, unlike gymnosperms, where the seeds are 'naked'
