Regenerating Planarian
This report will present the regenerating planarian. Planarians are tiny flatworms that live in freshwater. Planum means flat, which is how they got their name planarians. These teeny worms are generally hard to find considering how small they are. In fact, these creatures range from the size of 3 to 12 millimeters. Planarians are categorized as scavengers, they eat the decaying parts of dead animals. They have a tub where they are able to capture food and eat, which is called a pharynx. The Planarians are crossed eyed, these eyes are able to detect light in which planarians dislike. Planarians love to glide on their cilia. Cilia are little hairs that mostly surrounded on the bottom of the planarian. These animals have been able to regenerate because they are mostly made of stem cells. Planarians are examples of asexual reproduction. This means that planarians are able to reproduce without sex. This is why planarians are best to be used as examples for this lab. 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 …show more content…
Through the lab, the results went as expected. The data could have been more descriptive. Most of the planarians were mostly active, but by the end, the planarians had recovered. It was interesting to see how they would grow back. The hypothesis was correct, but the things went as

    Stem cells are characterized by their lack of specialization, self regeneration, and ability to produce a significant quantity of differentiated cells. These cells can be categorized into either embryonic stem cells or adult stem cells (Scadden, 2006). While embryonic stem are specifically pluripotent and arise from the inner walls of blastocysts, adult stem cells can be further segregated into germ line stem cells and somatic stem cells. Both divisions within the adult stem cells may have properties of either pluripotency or unipotency (Li, L. & Xie, T., 2005). The rate at which proliferation occurs and the maintenance of the adult stem cell’s identity is…

    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.…

    Cells specialize through birth when the embryonic stem cells take in different proteins that make them either be epithelial, muscle, connective, or nervous tissue. For example, stem cells can take in specific proteins to become epithelial tissue which protects the body’s surface, lines the internal organs, and composes the glands. The Eritrean man needed a new wind pipe that was constructed by cells that specialize in creating connective tissue that is meant to support the throat for the digestive system.…

    Our observations how planarian regenerate itself after cutting it in half led to this questions is this applicable to human in terms of regeneration and what is the role of stem cells in regeneration in comparison with planarians. As we observed how planarian regenerate itself. We followed how planaria regrow after cutting it in half along the transverse plane. During the experiment, we assumed that all parts of the planarian including the tail would regenerate due to cells that have the ability to specialize even in the adult form. Our experiment showed that it was possible from any part of the planarian to regenerate as well as a decrease in size during regeneration to allow growth of an entirely new section of its body.…

    This experiment was on Mendelian Inheritance; which is the inheritance of biological features that are based on the rules proposed my Mendel. The purpose of this experiment was to show how to predict patterns of inheritance by using Punnett Squares to perform monohybrid and dihybrid crosses. Two crosses were performed. Cross one consisted of heterozygous alleles crossed with another set of heterozygous alleles. Cross number two consisted of a set of homozygous dominant and homozygous recessive alleles. Completing the monohybrid and dihybrid crosses using Mendel’s Punnett Square system allows the results for the possible gametes to be viewed by the different alleles being crossed.…

    Genetics is a topic that has been studied for hundreds of years. One of the most notable geneticists was Gregor Mendel. Mendel studied basic inheritance patterns and gene expression using pea plants. Mendel determined that the offspring of two parents contains one gene from each parent (McKusick 1983). However, since Mendels discoveries in genetics, other scientists have found exceptions to Mendels rules, and have termed these exceptions Non-Mendelian Genetics. One type of Non-Mendelian genetic inheritance pattern is X-Linked traits (Brooker 1999).…
