Question

Which plant structures are common to all angiosperms?

spores
flowers
cones
endoskeleton

Answer 1

The plant structures that are common to all angiosperms are **flowers**. Angiosperms, also known as flowering plants, are characterized by the presence of flowers, which are their reproductive structures. The other options listed—spores (which are associated with non-flowering plants like ferns and mosses), cones (typical of gymnosperms), and endoskeleton (not applicable to plants)—do not apply to all angiosperms.
