Choose the correct statement about ovule arrangement in cycads.
(A)In all cycads, including Cycas, the ovules are borne on compact megastrobili with no primitive exceptions
(B)In all cycads except the genus Cycas, the ovules are borne on megasporophylls in megastrobili; in Cycas the ovules develop on individual leaf-like megasporophylls in what is regarded as a primitive arrangementCorrect
(C)In all cycads, ovules develop directly on the stem surface without any megasporophyll
(D)In all cycads, the microspores (not ovules) are borne on individual leaf-like megasporophylls
Answer: (B)
Solution
Most cycads bear their ovules on megasporophylls aggregated into compact megastrobili (cones), but Cycas is distinctive in retaining ovules on individual,
