Cycas has two cotyledons but not included in angiosperms because of
Naked ovules
Seems like monocot
Circinate ptyxis
Compound leaves
Correct answer: Naked ovules
Solution
Cycas is a gymnosperm, so it is not an angiosperm even though it has two cotyledons. The key difference is that its ovules are naked and not enclosed within an ovary, which is a defining feature of angiosperms.
