Ques. 1AIPMT 2001
Cycas has two cotyledons but not included in angiosperms because of
- naked ovules
- seems like monocot
- circinate ptyxis
- compound leaves
Answer
(1) naked ovules
Solution
As per NCERT, gymnosperms (gymnos: naked, sperma: seeds) are plants in which the ovules are not enclosed by any ovary wall and remain exposed, both before and after fertilisation.
In angiosperms the ovules are enclosed in an ovary.
∵ Cycas bears naked ovules (on megasporophylls), it is a gymnosperm, even though its embryo has two cotyledons.
