Do Plants Grow at Night?

Challenge using AnalyzingDigitalImages Software

Do plants grow at night? If so, how does the rate of growth compare to what is observed during the day? Calculate the growth rate of this Wisconsin FastPlant during the day and night.

Download the images of the leaves below and use in the AnalyzingDigitalImages software. Use the "Spatial" window and select the "Line" tool to measure the growth rates of the plant.

To download the image, either right-click or click and hold on the image. A pop-up menu will have the option to 'Save Image As...', which allows you to save the image on your computer.

You may do this to download most images available on the Internet.

See the Manual and Help Files on AnalyzingDigitalImages for guidance. AnalyzingDigitalImages is available in the DEW software bundle.
