For gymnosperm reproduction to take place, the male gametes need to somehow get to the reproductive parts of a female cone. But unlike the sperm cells of mosses or ferns, the gymnosperm and angiosperm male gametes are NOT free-swimming: they're inside something that protects them and keeps them from drying out. Do you know what that something is? And when that something lands on a female cone, do you know how the sperm manages to get out and fertilise an egg?
