| A major change in terrestrial vegetation took place in the Cretaceous with the evolution of the angiosperms, or flowering plants. |
| Populations of marine angiosperms, or seagrasses, are at the basis of productive ecosystems thriving in shallow coastal areas around the world. |
| Were the first angiosperms woody trees and shrubs, or were they small herbs? |
| These data suggest that the enzyme is well conserved in plants and could play similar physiological roles in angiosperms and gymnosperms. |
| Like other seed plants, angiosperms are heterosporangiate, producing pollen and ovules in different organs. |
| One copy of this gene occurs in angiosperms, but two copies occur in the other four seed plant groups. |
