Type: MCQ-conceptual-Medium-Class 11

In Cycas

A

ovule and microsporangia are present in same sporophyll

B

micro and megasporophyllus are present in same cone

C

male cone and megasporophylls are borne on the same plant

D

male cone and megasporophylls are borne on separate individual plants

Correct Answer

Option C

Detailed Explanation

In Cycas, a dioecious plant, male cones (microsporangiate strobili) and megasporophylls (female reproductive structures) are borne on separate individual plants, making option C accurate. Option A is incorrect because in Cycas, ovules are found on separate megasporophylls, not in the same sporophyll as microsporangia. Option B is also incorrect as microsporophylls and megasporophylls are not present in the same cone; they are located in different cones. Lastly, option D misrepresents the arrangement, as it correctly states that male and female structures are on separate plants, but does not specify the correct terminology for the cones involved.
