Beet Cell Membrane Lab
Title: The effect on temperature on beet cell membranes.
Introduction
A cell membrane or plasma membrane is very important in protecting cells. A cell membrane is a thin layer that protects the cells. The membrane is filled with lipids and proteins. The cell membrane protects the cell from ions and molecules that enter and exit the cells. I hypothesize that at -5 degrees Celsius, the color intensity will be a 1. I hypothesize that at 5 degrees Celsius, the color intensity will be a 2. I hypothesize that at 22 degrees Celsius, the color intensity will be a 3. I hypothesize that at 40 degrees Celsius, the color intensity will be a 5. I hypothesize that at 55 degrees Celsius, the color intensity will be a 7. I hypothesize that at 70 degrees Celsius, the color intensity will be a 10. (Campbell et.al, 2006)
Method I really enjoyed doing this lab experiment and am excited for more experiments. The key part about having a successful experiment is to be well organized. Before I started I made sure I had everything out that I was going to need. Next, I wrote down my hypothesis for each piece of beet in the different temperatures. I cut up the beets into 6 exact pieces that would fit into test tube. Then, I labeled each test tube so I didn’t forget which one was which. I ran water over the beets in a beaker for 2 minutes to get the betacyanin off from the damaged cells. Next, I put one beet piece in each test tube. Now that I was set up it was time to start the experiment. I placed tube 5 in the refrigerator and tube 6 in the freezer for 30 minutes. While waiting for those to sit, I moved on to the hot treatments. I started off by using hot tap water to see if the temperature was 70 degrees Celsius. The temperature was a little low so I placed the beaker in the microwave foe a few seconds and checked the temperature again. Then, I placed the beet from tube 1 into the beaker of water for one minute. After one minute, I placed the beet
