Development of the<br />
Microspore Mother Cells<br />
of Lilium candidum<br />
12 Microscope Slides<br />
With depictured accompanying brochure<br />
Leptotene, the chromosomes appear as fine<br />
threads<br />
Zygotene, the homologous chromosomes associate<br />
in pairs. The chromosomes appear as strings<br />
of beads<br />
Pachytene, complete pairing of the chromosomes<br />
Diplotene, shortening of the chromosomes by<br />
contraction. Interchange of chromatin between the<br />
maternal and paternal chromosomes (crossing<br />
over)<br />
Diakinesis, further contraction of the bivalents, the<br />
nuclear membrane disappears<br />
Metaphase and anaphase of the first (heterotypic)<br />
division, showing spindle threads. Two haploid<br />
sets of chromosomes are separated<br />
Telophase of the first and prophase of the second<br />
division<br />
Metaphase and anaphase of the second (homeotypic)<br />
division, two mitotic figures are present<br />
Pollen tetrads, four nuclei are formed after the<br />
second division, each bearing the haploid number<br />
of chromosomes. Formation of cell walls<br />
Uninucleate microspores after separation of<br />
daughter cells<br />
Mature two-nucleate pollen grains at the time of<br />
shedding. Each pollen grain possesses a tube cell<br />
and a generative cell<br />
Mature pollen grains, w.m. to show structure of<br />
the cell walls<br />
NEW! Microscope Slides on CD-ROM.<br />
The new amazing CD-Program for interactive<br />
learning and teaching in school and education<br />
comprise all necessary photomicrographs<br />
of microscopic slides, which can<br />
be observed by using a „Virtual Microscope“.<br />
Beautiful color drawings matching<br />
the slides, with detailed explanations<br />
(please see pages 129 – 136).<br />
