Effect of stress on beet cells

Effects of temperature on cell membranes. quinn pj

Lowest and highest temperatures denatures the plasma membrane and destroys or damages the cells and more concentrated and strong solvents stress the cell membrane and high degree of color was seen split out into the surrounding solution, indicating cells damage. All cells are made of plasma membranes, often called fluid mosaics. The water was still warm enough to allow the dye molecules to pass through the membrane. I found that the least amount of dye was leaked from the beet. For the room temperature and hot treatments I put each piece of beet into its marked test tube. Another variable could also be the freshness of the beets. When moving the beets we were careful to try not to stab, crush, or otherwise damage the cubes. Then, the colored rinse water was discarded. Phospholipid molecules have two parts and form a sheet that has two layers, called a bi-layer. In tube 3, the water was at When working with patients you need to understand the symptoms they have in order to help them. Results: Table 9.

The cubes of beet tissue were placed in a beaker and rinsed with tap water for two imiutes to wash the betacyanin from the injured cells on the surface.

The structures need to have a stable environment in order to establish their structure. The water was still warm enough to allow the dye molecules to pass through the membrane. Likewise, the composition from one membrane type to another is highly diverse. The cubes of beet tissue were placed in a beaker and rinsed with tap water for two imiutes to wash the betacyanin from the injured cells on the surface. Together they form boundaries or barriers between the cell itself and its surroundings, like the membrane of an egg. More concentration of the solvent shows more stress to cell. We returned the beet from test tube 2 and added 10 mL of distilled water at room temperature. I put the piece of beat into the beaker of water and waited one minute, I took it out and put it in beaker one, covered it with room temperature water and waited 20 minutes. After 30 minutes, I covered each one with the same amount of tap water and let them soak for 20 minutes. Results: Table 9. I think while doing the experiment the beets could have dried out slightly from the air in the house being so warm. That way I keep the side effects, such as nausea, to a minimum without overdoing the amount of morphine I give him. To determine the damaging effects Acetone and Ethanol concentration on cell membrane damage. Beet 2, 3 and 4 were all conducted the same way. Method The first thing that I did was label each test tube with numbers and listed each corresponding temperature on the label.

The head of this molecule is hydrophobic, which mean it is attracted to water and their tail is hydrophobic which means they dislike water.

I put the piece of beat into the beaker of water and waited one minute, I took it out and put it in beaker one, covered it with room temperature water and waited 20 minutes. We used cold and hot treatments for different test tubes.

I then patted them with a paper towel to get off the excess water.

Afterwards we cooled down the hot water bath to 55 degrees Celsius and immersed the beet from the tube 2 for 1 minute. Beet 2, 3 and 4 were all conducted the same way.

Gently, we placed each of the beet cubes into different, dry test tubes. In my experiment, I tried to cut each beet with precision. I left them in there for 30 minutes. Version Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. We have come to learn that cell membranes organize the chemical activities of cells. Now, any pigments in the innermost compartment spill out. Sickle cell disease occurs in individuals who inherit the mutated hemoglobin gene, from one or both of their parents.

In tube 2 the color was at a 7.
