Planarian Reaction Lab Report

If the result of a positive response was true, then the planarian would make a certain type of reaction to the light, such as wiggle, swim faster, or scrunch up in a ball. However if the response was negative, then the planarian would make any noticeable reaction to the light. The results of each planarian reaction differed because the experiment was not exactly performed the same on every organism. After slicing the planaria in half and testing the head and tail section, the head had the most positive reactions throughout all the planarian that were tested. 75% of the responses were positive and only 25% of them were negative or had no response. That means 3 out of every 4 planarian that was tested, came out to be a positive response to the
