Planarian Lab Report Hanna Klein Bishop Fenwick High School Planarian Lab Report Introduction 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

2015 Stem Cell Biology and Regenerative Medicine Analyzing the Effects of PZQ on Planarian Head Regeneration Abstract This paper focuses on the question of whether or not the drug PZQ (Praziquantel) has an effect on the double-headed formation of planarians. As the rest of the report will describe in more detail‚ we used multiple concentrations of PZQ reconstituted in 95% ethanol to observe its effects on planarians cut in a shape that promoted double headed growth. We used concentrations that we

Chloe Lindbom Regeneration of a Planarian Over Time Erin Davis Biology Mrs. Werfelman 5th Hour 10/09/2014 10/20/2014 Background: The planarian‚ also known as the flatworm‚ is a creature that live all over land‚ oceans‚ and freshwater. (Biggs‚ A.‚ Gregg‚ K.‚ Hagins‚ W.‚ Kapicka‚ C.‚ Lundgren‚ L.‚ Rillero‚ P.‚ 2002) The planarian has a threebranched digestive cavity. (Alvarado‚ 2004) Planaria range from 1/8 to 1 inch. (Alvarado‚ 2004) The planarian can be cut into many pieces and each piece will grow

Observation of Planarian Abstract: The objective of this lab report is to report our findings on the planarian. We extracted the planarian from a beaker and observed them under a microscope. We observed its sensitivity to touch on different parts of its body‚ its sensitivity to talcum powder‚ its reaction to a small piece of liver‚ and its sensitivity to light. Introduction: The problem we are investigating is how sensitive it is to touch on different parts of its body‚ its sensitivity to

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

Abstract Planaria belong to the class Turbella of the phylum Platyhelminthes. This paper depicts the behavioral reaction of Planarians to a variety of settings and compounds to better understand this particular Platyhelminthes. With a plastic syringe‚ it is possible to extract a sample of planaria‚ place into a Petri dish with enough freshwater and observe under a laboratory provided microscope. While on the microscope platform‚ expose your sample to light and darkness to notice the patterns of

Planarian Behavior – Biology II Honor Overview Work in pairs for this lab. You will directly observe planarian movement. You will then formulate a hypothesis about planarian behavior‚ and propose an experiment to test this hypothesis. Your experiment should be focused on one of the various types of stimuli listed below. Your experiment must collect both qualitative and quantitative data. Think about how you can increase the sample size of your observations to minimize the effect of confounding

Clint Casey Planarians I. Diet: Planarians are carnivorous and eat other smaller animals. They also eat detritus‚ diatoms‚ dead animals‚ and decaying organic matter. (1) II. Predators: Larger carnivores eat planarians. Some fish such as the Crossocheilus siamensis (Siamese Algae Eater) have been studied to remove planarians from fish tanks. (3) III. Range: Most planarians live in fresh-water bodies. They also live in all oceans‚ and in moist terrestrial habitats. (5) IV. Microhabitat:

Planarians reproduce A-sexually so they can basically clone themselves ‚ Because they reproduce A-sexually planaria and their genomes can be created over and over again .

Planarians A planarian is a small free-living flatworm. These flat worms are usually found under rocks in fresh water. They are part of the phylum Platyhelminthes and in the class Turbellaria. Planarians are usually zoophagous‚ they feed on small living invertebrates and decaying organisms found in their community. Some planarians could eat segmented worms‚ leeches‚ snails‚ and other small herbivores. Planarians may also be organisms that gain their food energy with the help of decomposing
