Cell anatomy

the intracellular fluid causes the cell to lyse and expand, destroying the cell and nucleus membrane of the cell. Strawberries are soft and easy to crush using a mortar and pestle. The purpose of pulverizing the strawberries is to destroy the plants cell wall. The cell wall is made up of cellulose, a hard insoluble material that is tough and rigid to protect cells. Physical force was required to break the cell wall and expose the nucleus of the cell. Animal cells are diploid organisms containing…

Describe the structure and function of a lysosome. Lysosomes are a cell organelle, translating as an independent structure within a cell, possessing a specific structure and function. For a lysosome its functions include; digestion of intracellular or extracellular material, nutrition from digested macromolecules and defence/protection from harmful substances. Lysosomes are variable from cell to cell in terms of shape and size but are conventionally spherical or oval shaped, 0.5µm in diameter…

There were five cells observed while conducting the experiment. The five cells consisted of cardiac muscle, elodea (a plant), paramecium (a protist), rhizopus stolonifer (bread mold, a fungus), and Bacterial cells (bacilli). Each cell was observed under high power lens (except for rhizopus stolonifer) with a total magnification of 400μm and a dFOV of 400μm. The estimated object size, scale bar, and drawing magnification of each cell was found except for cardiac muscle. Each cell appeared much…

include disagreements on how humans use animals in biological studies. Xenotransplantation, for example, furthers the use of animals for human benefit. Xenotransplantation, first discovered in the 1900’s, is a method of transplanting live animals cells, tissues, or organs from one species to another. It is becoming more common for animals such as pigs, goats, and monkeys to to be used as organ donors for humans, and it is possible it could save more lives in the future. Yet, Xenotransplantation…

Cells Research Assignment I. Define the following terms CELL NOUN The (usually) microscopic structure, known as a cell. Is the functional and biological unit of all organisms (life forms). INFERENCE NOUN Is a conclusion, idea and/or opinion that is reached on evidence, reasoning and the information that you have. It is simply, an educated guess. Synonyms implication, interpretation, deduction, reasoning, speculation, presumption, assumption. OBSERVATION NOUN 1. An act of viewing,…

In 2004, the National Health and Medical Research Council (‘NHMRC’) banned sex selection on moral and social grounds, except in the case of a serious genetic condition. However, recent debates in Australia have led the NHMRC to consider the prospect of lifting the life ban. It is inherent in such a culturally diverse society that the public cannot reach one consensus. While some believe that sex selection is unethical for ‘moral’ purposes, others believe that it is an ethical means of hindering…

Assignment 3.05 DNA DNA, deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and…

This means that to measure bacteria a person will have to count the cell numbers not measure the size of the cell. According to Frank O’Mahony, bacterial growth is affected mostly by temperature, nutrient, water supply, oxygen supply, and the acidity of the medium, which leads to the question of could vibrations from music affect the bacterial…

Summary/Response: “Human Reproductive Cloning: A Conflict of Liberties.” In this article “Human Reproductive Cloning: A Conflict of Liberties,” Joyce C. Havstad’s conflict is if cloning becomes safe and reliable, people should be able to have reproductive freedom. The author explained that promoters of human cloning know that it may lead to harmful characteristics. Instead of positively promoting human cloning they explain the causes and effects that could take place. They do strive to allow…

into the sample wells with a couple of sample wells left in between each of them in order to more easily compare the end results and avoid collision of substances. After making sure that each of the gels were transferred to the correct electrophoretic cell, the chamber was to be electrophoresed for 8 minutes before it was to be turned off. The location of each of the four proteins was to be recorded compared to the insertion point. Electrophoresis was to be continued if bromophenol blue (within…
