Investigation: Comparing Plant and Animal Cells
This simple investigation asks students to view cells under the microscope and compare differences between plant and animal cells. Students are instructed in the procedure for removing the epithelial cells of an onion and staining with iodine. These cells are fairly easy to see and most beginning students will have no trouble locating the…
