During the spring of the female cone's second year, the male and female gametes are ready. The pollen grows a pollen tube, which enters a little hole in the ovule's skin near its basal end, called the micropyle. The tube enters the ovule, and the sperm goes down the tube and into the ovule. When the sperm and egg fuse, fertilization occurs and ...

The cones have horizontal step-like fractures on their broken surfaces. You can simulate this kind of structure by firing a BB or small rock at thick glass, which produces a conical fracture and perpendicular steps.No less than 19 confirmed impact structures, and one shatter cone occurrence without related impact crater are now known from Africa.
