    Notes: Abstract Generative and sperm cells were examined at four stages of development from generative cell formation to sperm cell maturation using serial transmission electron microscopy. The generative cell and vegetative nucleus are associated in a male germ unit association during pollen maturation and tube elongation, except for generative cell mitosis. At late stages of prophase, this association loosens; the generative cell separates from the vegetative nucleus at metaphase. Slender, unbranched, or occasionally branched projections may be found at one or both ends of the generative cell, or they may be single, blunt, and short. Slender projections are rare during anaphase and telophase. The vegetative nucleus moves back into apposition with one sperm cell at the end of mitosis. During the re-establishment of the association, the vegetative nucleus first touches the end of the leading sperm cell and then moves next to the middle of the sperm nucleus. As the sperm cells enter interphase, a conventional association is re-established between one cell and the vegetative nucleus through one or more long and slender cytoplasmic extensions; these associations are maintained throughout later passage in the pollen tube. During maturation, a significant increase occurs in the surface area of the sperm cells (particularly in the sperm cell in association with the vegetative nucleus), and a lesser increase in nuclear volume and surface area. Other sperm cell parameters, including those of heritable organelles, remain unchanged during sperm cell maturation.

    Notes: Summary The structure of sperm cells and their association with the vegetative nucleus in pollen tubes ofNicotiana tabacum grown in styles were observed with the electron microscope, demonstrating the existence of a male germ unit. The two sperm cells are arranged in tandem and are closely associated with the vegetative nucleus, which always takes the lead. The leading sperm cell (SC 1) has a long and narrow cytoplasmic projection which lies within the enclaves of the much lobed vegetative nucleus, thus forming a physical association. The trailing sperm cell (SC 2) and the SC 1 are not only joined by a common transverse cell wall but also are surrounded by a periplasm bounded by the plasma membrane of the sperm cells and that of the vegetative cell, thus forming a structural connection. The sperm cells are elongated, with cytoplasmic projections at the anterior end of the SC 1 and at both ends of the SC 2. The cytoplasm of both sperm cells includes mitochondria, endoplasmic reticulum, dictyosomes, ribosomes, small vacuoles and axially oriented microtubules. No plastids were observed.
