Planarian Regeneration

November 14, 2014

Zoology Lab 7:00

Introduction
The planarians ability to regenerate their body parts have been known for over 230 years by observing how a small piece of a planarian head is dissected and capable of regenerating a complete organism. This is a similar research paper activity consisting of proving and observing the regeneration of the remarkable abilities that Planarians posse to replace body parts removed via amputation by dissecting a body section of the planarians’ body.
According to Phillip A Newmark and Alejandro Sanchez Alvarado’s from the article of Regeneration of Planaria, Peter Simon Pallas first described the regenerative ability of planarians in

5) Measure and record the length of the front (anterior) and the rear (posterior) pieces.
6) Gently place the separated or cut planarian back in the Petri dish using the pipet.
7) Measure the length of your control planarian without making any cuts. Gently place it back in the Petri dish.
8) Use the scalpel to make your cut for experimental planarian. Cut the planarian and record the chosen part:

9) Label your petri dish with your name and group.
10) Store the planarian: Light or Dark and the temperature it was kept.
11) Make sure there is water in the Petri dish. Cover the Petri dish and place it in a shady area at room temperature.
12) Clean up your lab area and return all materials The project consists of observing a non-parasitic flatworm commonly known as a planarian. Each group of students will observe and take care of their own specimen; these flatworms require clean water to survive. If not, the flatworm will dry out and die, so make sure your container has water at all times. Usually, each container will need to be refilled with water every three days, so plan and schedule accordingly. There are three planarian line cut categories and temperature and light may affect metabolism and regeneration

    Introduction: Dugesia tigrina, most commonly known as the Brown Planarian, are simple, small yet fascinating organisms. D. tigrina are “non-parasitic flatworms that have bilateral symmetry” which means their bodies can be divided into two symmetrical halves (Lobo et al 2012).…

    Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living, as well as dead, invertebrates, detritus or decaying organic matter. Planarians do not realize that are eating a lot, and can over eat resulting in death. Most planarians are freshwater forms that can be found underneath dead leaves, rocks or logs. Planarians belong to the order Tricladida. Most species range from about 1/8 inch to 1 inch. There are different species which come in white, gray, black, brown and sometimes transparent. Planarians are hermaphrodites, meaning they have both female and male organs. They reproduce sexually but they cannot reproduce by fertilizing their own eggs with their sperm. Planarians can also reproduce asexually by regeneration. Planarians have become a vital model system for studying tissue regeneration and stem cell characteristics because of their quick ability to regenerate. Studying planarians will build on our current knowledge in the fields of regenerative medicine and stem cell biology. Flatworms themselves are preyed upon by a variety of predators and are intermediate levels of the food chain, so they are important because they feed other animals.…

    Out of all 12 worms that we tested with PZQ and with ethanol, not one grew two heads, even after the second cutting 48 hours after their original dissection. Discussion The results did not provide an accurate answer to our hypothesis as it shows that the PZQ had no effect on the planarians two headed growth. We know this to be inaccurate because it is known that the PZQ does have an effect on double headedness when used correctly in certain concentrations according to reputable sources.…

    The ability to regenerate body parts is a more challenging process but is shared by Planarians, Annelids, some amphibians, most lizards, and many arthropods. This characteristic has evolved in such a variety of species mainly through convergent evolution. It is difficult to establish clear rules for regeneration ability among a larger diversity of organisms (Agata & Inoue 2012). In each phylum from sponges to mammals, there are regenerative species present (Agata & Inuoe 2012). A more challenging aspect of studying regeneration is the different levels at which it can occur. Many organisms regenerate entire bodies, limbs, organs, skin, hair and nails. Others have little or no regenerative properties. Regeneration is mostly found at higher rates in organisms at immature life stages. In crayfish, the anterior claws and legs can regenerate over time because they are not weight-carrying…

    In this report, it is shown how planarians are able to regenerate. This study was performed in views of how the stem cells worked. Thomas Hunt Morgan did a report just like this one using planarians. He was never able to figure out the experiment. All he was able to see was the growth of the planarians but was never able to see how the stem cells worked. Morgan used this experiment to begin his studies of inheritance. The lab shows that three planarians will be used, they will also be split in half . The partners will examine the planarians and see how they are able to regenerate. The hypothesis that was shown was that the planarians will grow into…

    Refugee, a novel by Alan Sunderland conveys the horrific qualities of Australia by showing us the view of a 12-year-old boy, a refugee who has to live in a detention centre for 12 months in the Australian outback. Sunderland condemns the fact that Australia has closed doors and is not letting refugees into its world. Sunderland encourages the reader to feel empathy for the plight of those seeking refuge from other countries and exhorts us to embrace an Australian Identity of acceptance. I define the concept of Australian identity as being loving, welcoming, and caring as well as the bonding of mateship and friendship. However, Alan Sunderland portrays the Australian Identity as racist, untrustworthy, and unaccepting towards refugees.…

    Raymond Carver’s “Cathedral” explores the evolving interaction between a disparaging narrator and his wife’s blind friend, Robert. The relationship Robert upholds over the years with the narrator’s wife, as well as Robert’s inability to see, breeds discomfort within the narrator’s already prejudiced mind. Judgement towards disability and race appear at the forefront of the interactions and internal monologue of the narrator. When confronted with Robert’s disability, the narrator expresses discomfort and scoffs at the ordinary nature of his manner. The misguided assumptions he makes before meeting Robert partially stem from the narrator’s values and the resentment he has built up.…
