Answer 1

Angiosperms have dominated the land flora primarily because of their power of adaptability in diverse habitats.

Explanation:

Angiosperms are land plants that have evolved to be highly evolved and well adapted. They have both vessels and tracheids in their xylem for better water conduction. To adapt to the climate, roots are transformed into tap roots, adventitious roots, pneumatophores, and so on.

Sex organs are well developed, sporophylls are organised into flowers, and the flowers are brightly coloured or attract pollinators at various times and locations. Insect pollination is more common than wind pollination because it is more efficient and results in less pollen grain waste. As a result, the flowers are designed to be appealing to a variety of insects. Seeds are better protected because they are enclosed within a fruit. All of these adaptations have made angiosperms more adaptable in a variety of environments.
