AIIMS 2017 Botany Reproductive Structures MCQ Question
In Cycas
ovule and microsporangia are present in same sporophyll
micro and megasporophyllus are present in same cone
male cone and megasporophylls are borne on the same plant
male cone and megasporophylls are borne on separate individual plants
Correct Answer
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.
