From thread-like chromosomes to mature pollen grains, get an in-depth look at the Madonna lily with the 12-slide set focusing on the development of the microspore mother cells of Lilium candidum. Slide set includes a full-color brochure with corresponding pictures. • Diakinesis, further contraction of the bivalents, the nuclear membrane disappears • Diplotene, shortening of the chromosomes by contraction. Interchange of chromatin between the maternal and paternal chromosomes (crossing over) • Leptotene, the chromosomes appear as fine threads • Mature two-nucleate pollen grains at the time of shedding. Each pollen grain possesses a tube cell and a generative cell • Mature pollen grains, w.m. to show structure of the cell walls • Metaphase and anaphase of the first (heterotypic) division, showing spindle threads. Two haploid sets of chromosomes are separated • Metaphase and anaphase of the second (homeotypic) division, two mitotic figures are present • Pachytene, complete pairing of the chromosomes • Pollen tetrads, four nuclei are formed after the second division, each bearing the haploid number of chromosomes. Formation of cell walls • Telophase of the first and prophase of the second division • Uninucleate microspores after separation of daughter cells • Zygotene, the homologous chromosomes associate in pairs. The chromosomes appear as strings of beads
