Unformatted text preview: early germination. Angiosperms that develop two cotyledons. The mature female gametophyte. The fertilized central cell, which is triploid (3n) and will form tissue that feeds the developing embryo and then dies. Axillary meristems that arise from the axil junctions of the bract and stem. The haploid (n) stage of the plant life cycle that makes the male (sperm) and female (egg) gametes. The pollen grain absorbing water and extending a pollen tube for fertilization. The uppermost cell of the suspensor, which in some species will become the root apical meristem. A shoot apical meristem that has shifted from making leaves (vegetative development) to making flowers (reproduction). Female spores. The end of the embryo sac nearest the egg. Male spores. Angiosperms that develop a single cotyledon. The base of the pistil, which contains the ovules. An outgrowth of the ovary of a seed plant that houses the embryo sac, and will eventually encase the fertilized zygote and become the seed. Reference Often colorful parts of a flower that attract pollinators and originate from whorl 2. The female reproductive organ. A compact and sturdy cell designed to bring the male gamete to the appropriate female gamete. A tube which is extended by the germinating pollen grain through the stigma and into the style of the pistil and which will allow the male gamete to get to the egg for fertilization to occur. Pollen grains of the same species landing on the stigma and germinating. A fertilized zygote that has become encased by the seed coat. Photosynthetic leaf- like structures at the base of a flower, w...
