female gametophytes. Gametaphytes of gymnosperms are microscopic and completely dependent on the large, free-living sporophyte. Pollination is the transfer of pollen from male cones to female cones, which house the eggs. Pollen is carried from the male cones to the female cones by the wind. Sperm of cycadophyta are flagellated. Phylum Ginkgophyta consists of one species, Ginko biloba, a large dioecious tree that does not bear cones. Phylum Coniferophyta are the large group of cone- bearing plant that includes

begin? Scientists identify the first moment of human life as that instant when a sperm cell unites with an ovum or egg cell.
