pict Experimental Planaria #1 Cut in half into front (anterior) and rear (posterior) Day 1 Measuring the Planaria This operation is best performed by removing some of the water from the dish into the lid with a clean pipette and waiting for the worm to stretch out. Measure the length of the worm in millimeters. (Always replace the water right away, you can use the dish lid to transfer water to and from the planarian environment.) A. Record the length of the front (anterior) section just AFTER you cut. This is your INITIAL front length: 5 m m B. Record the length of the rear (posterior) section just AFTER you cut. This is your INITIAL rear length: 3mm C. Observe and record any behavioral responses just after your cut Day 2 Spend time under the microscope observing the cut Planaria. Answer the following questions based on your observations. NO measurements will be taken on this day. a) Are the cut fragments showing signs of regeneration? b) How did you identify the regenerating portion? What color does it look like? Investigation
