The oospore that is formed by the union of the sperm and the egg grows and becomes the em- bryo of a new pine plant. The tissues that surround this developing embryo are partly absorbed by it and used in nourishing it. By the time the embryo has developed root tip, stem tip, and young leaves, the walls of the ovule have begun to harden, and the whole structure is recognized as the seed (fig. 226). When the pine cone opens, usually two years or more from the time when pollination occurred, the seeds fall to the g
