This is a picture of a common daylily which shows the anther and filament of a stamen. This is where the pollen of a flower is stored and produced. The anther holds the pollen while the filament, a long stem-like structure, holds the anther up so pollinators can reach it. The anther can either be placed at the end of the filament (as pictured) or towards the center.

These eggs are composed of a hard or leathery shell, an amnion, and a fluid-filled amniotic sac. Amniotic eggs are produced by birds, reptiles, and egg-laying mammals.  

This is a picture of pine needles which are an example of a gymnosperm leaf.

This is opposed to angiosperms which protect their seeds with flowers and/or fruits. Other examples of gymnosperm leaves are spruce, fir, and hemlock needles.
