1. “Comparing and Analyzing Cell Size Using ImageJ”
Summary: In this activity students will measure and analyze cells using ImageJ. Based on their findings they will classify each cell as either prokaryotic, eukaryotic, or neither. By observing the different cells, students should be able to compare and contrast the two types of cells.
“What do you need in an image to accurately measure an object using ImageJ?”
“What characteristics (besides size) could help classify these cells as either pro- or eukaryotic?”
“What are 3 defining characteristics between prokaryotic and eukaryotic cells?”
“From the group of images, which were prokaryotic? Eukaryotic?”
“Which cells evolved first – prokaryotic or eukaryotic? Why?”
