Pollination cones (female), but some species are monoecious and others dioecious. A pollen cone contains hundreds of microsporangia carried on (or borne on) reproductive structures called sporophylls. Spore mother cells in the microsporangia divide by meiosis to form haploid microspores that develop further by two mitotic divisions into immature male gametophytes (pollen grains). The four resulting cells consist of a large tube cell that forms the pollen tube, a generative cell that will produce two sperm by mitosis, and two prothallial cells that degenerate. These cells comprise a very reduced microgametophyte, that is contained within the resistant wall of the pollen
The Grain of Wheat than the original. The image of the grain of wheat dying in the earth in order to grow and bear a harvest can be seen also as a metaphor of Jesus' own death and burial in the tomb and his resurrection. The Rev. William D. Oldland in his sermon "Unless a Grain of Wheat Falls into the Earth and Dies" said: The Apostle Paul also says: "What is sown in the earth is subject to decay, what rises is incorruptible" (1 Cor. 15:42).
