Use the links below to open the photo and gravitropism movies that were made from the plants that were supposed to be available for the tropism lab.

There are 2 phototropism movies and one gravitropism movie that are the same ones from which the still images you received in class were obtained.

These are Quicktime movies so you will need to have the Quicktime plug-in for your browser.

The images were captured at 5 min intervals for all movies and are played back at 6 frames per second. So, 2 secs (12 frames) represents one hour of real time. By advancing the movies one frame at a time, you can see how much (or little) movement occurs in 5 min.

The movies will open in separate windows.
