How Does Chemical Stress Affect Beet Cells

338 Words2 Pages

Chemical stress affected the cell membrane of a beet cell, because of the higher amount of ethanol added to the beet. For example, we added 1% ethanol, 25% ethanol, and 50% ethanol to 3 test tubes with 15 mm of beets inside. We left it with no air inside for 30 minutes then tested the absorbance of the ethanol without the beet. The class got roughly 0.273 for the 1% ethanol, 1.205 for the 25% ethanol, and 1.882 for the 50% ethanol concentration. In each solution, the ethanol was a bit redder than the last. In the pre-lab, we read a few paragraphs on the process of the cell membrane and what happens with a beet cell membrane. We now know that beets contain a red pigment called betacyanin, which is located in the vacuoles of the cells. We learned that as long as the cell and the membranes are intact, then the betacyanin will stay in the cells. …show more content…

This proves that chemical stress affecting the cell membrane of the beet was caused by the adding of ethanol in higher concentrations because the alcohol affects the cell membrane by attaching the cell membrane like water does cause it the changing shape and create a hole big enough for more alcohol to get in. This also causes alcohol to damage the vacuole causing the betacyanin to get released and the red pigment to get transferred into the ethanol around the beet. In conclusion, the chemical stress affected the cell membrane of a beet cell, because of the higher amount of ethanol added to the beet caused the cell membrane to change shape which resulted in the betacyanin being released from the cells. These results affect me because I have always wanted to understand why anything that the beets get mixed with, food, water, bowls, etc, will turn

How Do Honey Bees Affect The Environment

370 Words | 2 Pages

Land organisms have the ability to regulate their body temperatures in order to survive in the environment and scientists are digging deep in research and observation in order to figure out how the honey bees function in different temperatures of their surroundings. Different variations in temperature of the environment are a facing threat to most land animals and more specifically flying organisms. Because there is a zone in which contains the most compatible temperature for them to have maximum ability to function properly, they will not most likely cannot survive in extreme temperatures. However, the structures and their bodily system such as the proteins and enzymes that provide a solution. It has little effect on the drastically changing

Previous experiments on the subject carried out this procedure once or twice a day. We conducted this process once a day at 9 a.m. to observe how the smallest amount of stress altered the plant’s development. Nitrile gloves were worn during the encounters to reduce any chemical exchange between the hands and the plant surfaces. After measurements were recorded, each plant was watered at the base of the shoot with 0.5 oz. of distilled water. None of the leaves came in contact with the water to ensure that the plant’s responses would only be affected by touch.

Mitochondrial Activity Lab Report

First, it was hypothesized that test tube "A", the control, would not show any red concentration, test tube "B" which contains supernatant II would show the most red concentration and test tube "C" which contains sediment II would only show a little red concentration. The second hypothesis states that the raw corn kernels would have mitochondrial activity while the boiled corn kernels would not. The last hypothesis interprets that the "gunk" and sediment I will both contain starch granules. It was only expected to find mitochondrial activity in Supernatant II. Unfortunately, after performing this experiment, we were not able to support this hypothesis and come up with a conclusion.

Catechol oxidase is found in cell cytoplasm, their function in plants are to "help protect damaged plants bacterial and fungal disease." The objective of this experiment is to test the presences of catechol oxidase in various fruits and vegetables. Our group hypothesis states that, If catechol oxidase is present in the selected extracts, the null hypothesis is that catechol oxidase is not present in the selected extracts. Next, the prediction would be, if catechol oxidase doesn't differ with other enzyme sources, then the rates will

Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

1% glucose, 1% maltose and 1% lactose all progressively get positive results by changing colours to reddish brown at the end of this experiment. In this case the aldehyde functional group that is present in the products (monosaccharides and some disaccharides) in this reaction is able to reduce copper in the presence of alkali and this produces colour changes while converting to an aldose sugar. Honey is made of fructose and glucose which instantly turned brown after the test-tube was placed in the boiling water because of its active aldehyde and carbonyl group. The copper (II) sulphate present in the Benedict’s solution reacts with electrons from the aldehyde group which results in a redox reaction to from cuprous oxide, a red brown precipitate that seen in all of the above mentioned solutions (Hill, 1982). Beer also gave positive results because it contains aldehydes and ketones (i.e. acetone, trans-2-butenal, furfual) during its beer production process where the sugars are converted through fermentation (Hill, 1982).

I predicted that the control would have a higher alcohol content than the experimental since beta and alpha amylase are working together. Since only Alpha-Amylase worked in the experimental, there was probably bigger carbohydrates present in the flask, therefore, there was a lower alcohol percentage since yeast can’t digest bigger sugars. b. My results also matched my prediction regarding mean reducing carbohydrate levels during the mashing process between the control and the experimental. My prediction stated that there would be less reducing carbohydrate ends in the experimental, which was proven in the data table.

UNHEALTHY CELLS = SICKNESS The cellular environment is affected by stress in general, physical, chemical and emotional stress suffered by the individual. At the cell level, it is always a chemical stress, and a harmful chemical environment is produced. It is the stress molecules such as catecholamines (adrenalin and noradrenalin) and steroids (e.g. cortisol) that are presented to cells following neuroendocrine responses as a result of all kinds of stress experienced by the individual.

Joshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.

Biology Design Practical Joshua Edwards What are effects of the volume of a potato and the amount of weight it loses when placed in salt solution? Introduction This design practical uses a potato’s surface area to volume ratio to see what affects it has on osmosis in different concentrations. Osmosis is the movement of water molecules through a cell membrane into an area of a higher solute concentration. The movement goes the way of the solvent with more solute because the lower solute concentration is drifting through balancing the ratio of solute per solvent (En.wikipedia.org, 2018).
