This
picture of leaves that belong to a pine tree is are examples of gymnosperm
leaves. These leaves are able to produce either seed cones or pollen
cones. These leaves are classified as gymnosperm leaves because they produce
gymnosperm seeds, which are seeds that don't have the ovules covered all the
way by sporophyte tissue while it's pollinating. The seeds that fall from this
leaf are considered to be "naked seeds" as a result of the incomplete
covering.
