Answer 2

Gymnosperms refers to the group of naked seed bearing vascular  plants. Their seeds are naked as these are not enclosed in an ovary, like that of the angiosperms. This group includes large trees, like the pines, conifers, cycads and Ginkgo.  

The reproductive structure of gymnosperms is the strobili (cone), which consists of an ovoid, cylindrical, or spherical cluster of sporophylls (cone scales) arranged around a central axis and differ largely in size from the small pollens and ovules of angiosperms.
