This is a time-lapse movie of microtubules (visualized using a GFP-Tubulin reporter) in a living plant cell. Shown is a cotyledon epidermal cell from an Arabidopsis thaliana plant. Note the microtubules display dynamic instability---stochastic switching between periods of growth and shortening as tubulin subunits are added or removed from the microtubule. The movie is played at 10 frames per second, or 50x real time. The bar represents 10 microns (1/100th of a mm). For more, visit http://www.botany.ubc.ca/wasteneys/.
very nice to see a scale bar in a movie, but it's got no label!
