· Most conifers, or cone-bearing trees, have and male pine cones on the same tree. A pine cone, also called a megasporangiate strobilus, consists of cone or seed scales that hold two ovules, the unfertilized seeds. It takes about two years for pine cones to become mature. When the seed matures, the cone opens up, exposing the ...
Gymnosperms or coniferous trees produce both male and cones. The male cones release pollen which is carried by the wind to a cone. A pollen tube is formed and pollen is transferred to fertilize the cone''s egg. This fertilization develops into a seed. Each scale of a pine cone encases a seed.
Pine Life Cycle. Stage 1: Male cones (pollen cones) and cones (ovuliferous cones) are formed on the adult tree or the spore-bearing plant (sporophyte).
