Detailed explanation-3: -Gymnosperms have pollen but no flowers. Pollen is made by the male cones from microspores that come from microsporocytes created during meiosis. Using the wind, the pollen granules pollinate the female cones. Gymnosperms came into existence in the early Mesozoic era about 359 to 299 million years ago.
