...Cell Structure and Function AbstractThis report is about cell structure and function. The cell is the basic unit of life. All living things are madeof cells. By doing this lab, I hoped to learn how a cell looked and how it functioned. I also wanted toknow the differences between prokaryotic cells and eukaryotic cells Introduction The concept of this lab is producing a replica of an animal cell, and a plant cell. Producing the models of the cells helps to provide a better understanding of each cell and its contents also, to explore thedifferences between prokaryotes and eukaryotes. Cell theory states that all cells reproduce new cells,while passing their genetic information. In addition, cells make up all living things, metabolize energyand that the chemical make-up of cells is similar. The objectives for this lab are to gather the materials,which include gelatin packs, plastic bags, water, Tupperware, bowls, and some small various householditems. The other objectives are preparing the gelatin as directed, gathering the household items that willserve as cell organelles, pouring the gelatin in the bag and placing the items in the plastic bags. Thenplace the cell replicas in the refrigerator for 24 hours. Results After twenty-four hours, I removed the cell replicas from the refrigerator and observed them. They didnot look exactly like I planed but they were understandable. Discussion Replicating the cell structures provides better understand the structure and...

...Chemistry of Life – Lab Report The purpose of this lab exercise is to perform chemical tests on a variety of foods to identify the presence of any major molecules essential to life. After acquiring the results we will analyze them and we will be able to describe the general chemical content of those foods. In order to determine which specific major molecules were present in certain foods we conducted four different tests. The iodine test tested for starch by putting a few drops of iodine on a food substance. If the food turned a blue-black color then it was positive for starch. The Benedict’s test tested for the presence of sugar. In order to test you put 1 ml of solution to be tested and add an equal volume of Benedict’s reagent in a test tube and heat in a water bath for two minutes. If the solution goes from blue, to green-yellow, then to a red-brown color it means it is positive for sugar. The next test is the Biuret test and its tests for peptide bonds in proteins. To test you add a few drops of Biuret reagent to a food substance. If it turns a violet-purple color then it is positive for protein. The final test is the Grease Spot test for lipids. If there is a “grease spot” present after conducting this test, then the food tested positive for lipids. The first group of foods that were tested was the fruits and they consisted of apples, bananas, plantains, and avocados. The apple, banana, and plantain contained starch and sugar and this is correct because these two...

...It is like something out of a sci-fi movie; Scientists injecting genes from an animal into the genes of a plant in order to create one super crop. As weird as this may sound, it is exactly what’s going on now, and these super crops are known as Genetically Modified Organisms, or GMOs. These crops are becoming more and more accepted in today’s agriculture business. This type of bioengineering is being used to yield more crops and curb the effects of herbicides. But the risks in using GMOs may far outweigh the benefits. GMO foods are becoming increasingly available and are a threat to our health and our agricultural system. Basically GMOs are organisms that have had their genes altered through bio-engineering. These plants and/or animals have their genetic makeup changed, usually in a lab, in order to add or remove certain characteristics. Genes from other animals, viruses, or bacteria are artificially inserted into organisms in order to create new organisms that would not occur naturally. Corn, for example, has been genetically modified to produce its own pesticide and resist herbicides. Nearly 70% of all the corn grown in the United States was modified in this way. (Smith) And if you look at the ingredient list of almost any packaged food, you’ll see that there is corn in almost all of it. Corn is also the main ingredient in much of the feed given to farm animals, such as pigs and cows. So no matter what you eat, it is almost certain to contain some amount GM (Genetically...

...Human cloning occurs naturally with phenomena like twins and triplets, but the same outcome of a genetically identical individual created in a lab is not as well received. Over the years, cloning has transformed from a thing of fantasy to one of reality. Current research is bringing us closer than ever to cloning humans, but what will happen if we succeed? The word clone is defined as being an exact genetic replica of a molecule, cell, plant, animal or human being. The term cloning refers to the technological process of creating a clone. The use of cloning technologies has been in place for the past 50 years, though it wasn’t until 1996 that the first mammal was cloned from a somatic cell. Dolly, the world’s first cloned lamb, brought cloning and its ethical implications into the spotlight after she was successfully cloned from an udder cell of a six-year-old sheep. Dolly was put to sleep in 2003 after suffering from lung disease, as well as premature arthritis. Having lived only six and a half years instead of the expected 11 – 12, Dolly’s passing also brought to light questions regarding the health and life expectancy of cloned animals. Though her life was short, she left a long lasting imprint in the field of modern biological research. The successful cloning of Dolly led to many other advances in the biological community, however, as of 2014 no human has ever been successfully cloned. Human cloning is a hotly debated topic in the science and religious communities...

This process grows an organ made of similar cells to humans and then transplant it in the patient.

...LEON VASQUEZ 3020 "LAB REPORT" #5 CELL TYPES AND STRUCTURES OBJECTIVE To observe the two main types of cells and their typical structure. INTRUDUCTION * PROKARYOTE:Any cellular organism that has no nuclear membrane, no organelles inthe cytoplasm except ribosomes, and has its genetic material in theform of single continuous strands forming coils or loops, characteristics of all organisms is the kingdom Monera, as the bacteria and blue-green algae. a cell lacking a true membrane-bound nucleus; * EUKARYOTE: is an organism with a complex cell or cells, in which the genetic material is organized into a membrane-bound nucleus or nuclei. * PROKARYOTIC CELL PROKARYOTIC CELL CHLOROPLAST: Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. * AMYLOPLAST: A nonpigmented organelle, or plastid, occurring in the cytoplasm of plant cells. Amyloplasts transform glucose, a simple sugar, into starch through the process of polymerization, and store starch grains within their stretched membranes. * CHROMOPLAST: Are plastids, other than chloroplasts, that produce and store pigments. Found in flowers, leaves, roots and ripe fruits, they contain carotenoids (lipid-soluble pigments ranging from yellow to red in color), which lend color to the plant tissues containing them...

...flowers on passive smoking (PS) induced hyperlipidemia in rats had been evaluated. Hyperlipidemia was induced by passive smoking in a closed chamber having 1 burning ciggrette inside it. The hypolipidemic activity was analysed by reading the blood serum level in UV at 505 nm after treated with reagent present in auto span diagnostic kit. Dose of Methanolic extracts of QI had been prepared by using distilled water i.e. 200 mg/kg p.o. Methanolic extracts of QI significantly reduce the harmful lipid layer in blood serum at varying concentration and dose dependent manner which shows that the plant carries the hypolipidemic properties. It reduces the LDL, VLDL, cholesterol, triglyceride and raise HDL level in blood serum upto certain extent which was may be due to the inhibition of lipid peroxidation as the plants contain some active ingredients acting as antioxidants. Our result shows that the plants extracts recover the disorders in lipid metabolism noted in hyperlipidemic state.
