Worm Regeneration Experiment

Improved Essays
Worm Regeneration Experiment Analysis In class, an experiment was conducted involving planarian worms and their method of using regeneration to regrow parts of their bodies when severed and separated from the other half. In order to conduct this experiment, a small planarian worm was obtained from a glass of spring water using a pipette, and then placed into a petri dish filled with enough spring water to keep the worm alive (But not enough that could allow the worms to escape). Then, using a razor blade, the planarian worm was cut in half to produce two worms (in my case specifically, separating it into two equal halves), and was then observed over the course of two weeks to witness the regeneration process. Microscopes were provided if needed …show more content…
For a week, the head segment didn’t change in size at all, and remained 1 mm long (the length it was when I first cut the worm). However, after 1 week, the body segment had grown one millimeter, from 3 mm (original length) to 4 mm. After 2 weeks, the head segment had grown to 2 mm, and the body segment had remained the same at around 4 mm. The slight changes in the two halves go along with my predictions, and show that while the halves did regenerate, it was in very small amounts. This experiment went along with what I had initially expected, and proved my overall hypothesis and predictions. Overall, this experiment was a success regarding observing worm regeneration and proving a hypothesis. I predicted that my worm’s small size would impact the amount of regrowth it would experience, and my results prove that both segments only grew a maximum of 1 millimeter over the course of 2 weeks. After severing my planarian worm in half and recording the results of it’s regeneration, it’s safe to say that these worms definitely regenerate, but because they come in different sizes it’s harder to observe large changes over extended periods of

    A digestive tract, reproductive organs, and blood vessels could be seen inside the earthworm. The mouth led to a pharynx, esophagus (which was covered by the reproductive organs), a soft crop, hard gizzard, and an intestine that continued on to the rest of the body. The earthworm’s brain was barely visible. A pair of small, white, ball-shaped seminal receptacles lay on each side of the earthworm, along with two pairs of larger, whitish seminal vesicles below them. Beneath the reproductive organs, a dark aortic arch was visible.…

    We discovered that the sow bugs had an overall negative reaction towards this environment. We inferred this as we watched and studied the behavior of sow bugs. We knew they had a negative reaction towards the damp environment when they went towards the piece of paper towel and rearing back and going back towards the control or to the dry side. The trend that we saw in the bugs with no reaction was that they were smaller in size. All they wanted to do was remain in the middle of the container, vs. the larger worms who were more active.…

    Introduction This experiment was conducted to measure the change in the Planarian’s speed according to different light frequencies. This experiment is relevant to a Planarian’s natural life as Planaria live in many different environments, and under several light variations. Planaria are found in both salt and fresh water, as well as amidst logs, soil, and a variety of plants (Conservation Commission of Missouri, 2015). This immense variety of environments corresponds with a variety of light sources, colors, frequencies and intensities.…

    This experiment was conducted to determine the effects of environmental factors on the regeneration of planarian tail length. Regeneration is the process of regrowth and repair of body parts. This process can occur in many organisms, especially in planaria. The effect of light exposure (full light, shade, dark) on the regeneration of tail lengths of planaria, Dugesia tigrina, was used to test the hypothesis that planarian will regenerate more when placed in complete darkness. 12 planaria were used total in this experiment, 4 in each exposure of light.…

    Evaluation: The graph that was produced shows that Whitefish Blastula cells spend the most amount of time in interphase followed by prophase, metaphase, anaphase and finally telophase. Relative time was found by finding the total number of cells in each phase and then dividing it by the total number of all cells counted and finally multiplying by 100. Doing this showed that the cell that takes up the most amount of time is interphase at 71.35%. Although I was unable to confirm the accuracy of the relative times found in the experiment because there was no information available the time taken in interphase compared to the other cells is probably correct.…

    Project Name: The effect of sugar and salt solution on the chemotaxis of planarians Introduction Questions: The research question is, “What is the effect of sugar and salt solution on the chemotaxis of planaria?” This research question is worth asking to see if planarians have an affinity toward salt or sugar solutions. By studying different types of organisms, we are better able to see the type of environment that organisms like to live in. This allows us to have a better understanding of organisms today especially the Platyhelminthes or other flatworms. What this question teaches us about biology is that it shows us the effects that the systems of Platyhelminthes have while being in different types of solutions.…

    This hypothesis is tested by excising only one-eye and examining the behavioral pattern of Planarians under light conditions. We would expect Planarian to move in circles if using Tropotaxis as a mechanism for reacting to light. In addition, my study will explore Planarians’ behavioral pattern when right-eye is excised as compared to left-eye only. My hypothesis is that both patterns (left eye excised vs. right eye excised) will be a mirror image of one another. The other possibility would be that worms do not use photo Tropotaxis, therefore they will process rays of light…
