Accepted Answer

A)  Male cones are composed of tightly sealed herbaceous scales that protect the pollen grains from insects. Female cones are composed of woody scales to protect the female gametophytes from animals. 
B)  Both male and female cones are designed to attract pollinators. Once fertilization occurs, female cones open to attract animals to aid in seed dispersal.
