Q.
Cycas has two cotyledons but not included in angiosperms because of
AIPMTAIPMT 2001Plant Kingdom
Solution:
Cycas belongs to order cycadales of gymnosperms because it has naked seed. It is not enclosed inside a fruit. It does not have double fertilization and so the endosperm formed is haploid in nature and not triploid. So it is not included in angiosperms as they have ovules (or seeds) produced 46 inside fruit. This is the main difference between gymnosperms and angiosperms.
