The events of meiosis I in a living insect spermatocyte beginning at metaphase with meiotic bivalents at the spindle equator followed by anaphase , segregation of bivalents to the spindle poles and t...

Movie of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis that have been experimentally flattened. Time-lapse polarization microscopy using a Nikon Microphot SA, equipped for...

This is a live image of the bdelloid rotifer Philodina roseola under 20x magnification. Bdelloid rotifers are microscopic freshwater invertebrates best known for their capacity to undergo frequent cyc...

Movie showing showing the dynamics of kinetchore microtubules during meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis that were experimentally flattened. Time-lapse polarizatio...

Desmid Micrasterias, a chlorophyceae alga of extraordinary beauty, beginning to divide. Micrasterias have bilateral symmetry, with two mirror image semi-cells joined by a narrow isthmus containing th...

The events of meiosis I in a living insect spermatocyte beginning at metaphase with bivalents at the spindle equator, followed by anaphase onset, chromosome segregation and the start of cytokinesis. T...

The movie shows several sequences showing changes in birefringence in oocytes of the marine annelid Chaetopteris that had formed meiotic spindles before exposure to centrifugal force in the Centrifuge...

Time lapse movie showing several sequences of mitosis in pollen mother cells of the Easter Lily recorded in 1951 on 16 mm film with an early polarizing microscope developed by Shinya Inoue. The work w...
