What type of reproduction does Cycas have?
Sexual Reproduction
Cycas is heterosporous. It produces two kinds of spores. It is dioecious, i.e. male and female reproductive parts are borne on different plants. The sexual reproduction is oogamous, i.e. the egg is quite large in size and non-motile compared to male gametes.
