Q

More than 67% of angiosperms are

A

eudicots

17
Q

eudicots (Eudi)

A

because they have two cotyledons as a seedling

18
Q

monocots (Mono)

A

because they have one cotyledon as a seedling

Q

Eudicots Fact

A

More pollen openings may have led to evolutionary success compared to other angiosperms.
