Question

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

Answer 1

The correct option is D Male cone and megasporophylls are borne on separate individual plants

Cycas is dioecious i.e. male cone and female cone (lax) are borne on separate sporophytes. Each microsporophyll of male cone bears many microsporangia in its adaxial surface. The female cone has loosely arranged megasporophylls, each of which bears ovule in the middle part.

So, the correct option is D.
