c) Sketch your regenerating part for each fragment.d) What is the regenerating portion called?e) What are the stem cells in Planaria called? What is their function?f) Discuss behavioral response (movement, response to touch, light) observed for the tailfragment which is regenerating a new head.g) Discuss behavioral response (movement, response to touch, light) observed for the headfragment which is regenerating a new tail.h) How do you think Planaria actually DO the regeneration? What might behappening to their cells? How might regeneration be possible? Experimental Planaria #1Cut in half inte front (anterior) and rear (posterior)Day tMeasuring the PlanariaThis operation is best performed by removing some of the water from the dish into the lid with a cleanpipette and waiting for the worm to stretch out. Measure the length of the worm in millimeters. (Awaysreplace the water right away, you can use the dish lid to transfer water to and from the pianaranenvironment.)A. Record the length of the front (anterior) section jusAFTED you cut. This is yourINITIAL front length: 5m 6)B. Record the length of the rear (posterior) section just AF TERGU cut. This is yourINITIAL rear length: mroC. Observe and record any behavioral responses just after your cutDay 2Spend time under the microscope observing the cut Planaria. Answer the followingquestions based on your observations. NO measurements will be taken on this daL.a) Are the cut fragments showing signs of regeneration?b) How did you identify the regenerating portion? What color does it look like?

Since you have posted multiple questions of observational type, we will answer the few questions for…

Answered: d) What is the regenerating portion…
