Lilium longiflorum
Biological Process
meiosis
Cellular Component
nucleus
Post meiotic formation of a tetrad. Each of the four cells produced by meiosis are now separated from each other by cell walls. Each of the four nuclei contain the haploid number of chromosomes.Once...

Lilium longiflorum
Biological Process
meiosis
Cellular Component
nucleus
Prophase I of meiosis, diakinesis substage in a diploid lily pollen mother cell. One bivalent is shown. It has 6-8 crossovers (also called chiasmata). The long arrows point at definite chiasmata; ...

Lilium longiflorum
Biological Process
meiosis
Cellular Component
nucleus
Metaphase I of meiosis, polar view, in a diploid lily pollen mother cell. Because of the polar viewpoint, the metaphase plate is not apparent but the 12 bivalents are very clear as are the regions o...

Lilium longiflorum
Biological Process
meiosis
Cellular Component
nucleus
Telophase II in a diploid lily. The segregated chromomosomes on the left side of the micrograph are a little in advance of the ones on the right side . The nuclei on the left are reforming their nucl...
