The effect of temperature on beet cell membranes
Introduction:
Cell membrane is the plasma like substance that separates different organelles and molecules within an organism. The cell membranes vital function is to permit passage of protein and enzymes through their wall. Red beets, also known as Beta Vulgaris has a red pigment that is located in its large central vacuoles. It is my hypothesis that if the cell membrane is to experience extreme temperatures, then it’s most likely it will affect the membrane. * I hypothesized that at 70 degrees Celsius, the tonoplast will damage and the color intensity will be a 10.   * I hypothesize that at 55 degrees Celsius, the tonoplast will also damage but that the color intensity will be a 4.   * I hypothesize that at 40 degrees Celsius, the tonoplast will suffer a slight damage and the color intensity will be a 2.   * I hypothesize that at 22 degrees Celsius, the tonoplast will not experience any damage sue to the fact that it isn’t experiencing any stress or extreme weathering and the color intensity will be a 0.   * I hypothesize that at 5 degrees Celsius, the tonoplast will suffer a slight damage and the color intensity will be a 2.   * I hypothesize that at -55 degrees Celsius, the tonoplast will not experience any damage sue to the fact that it isn’t experiencing any stress or extreme weathering and the color intensity will be a 0.

Method:
The experiment was conducted by first reading the directions for my experiment and then gathering all the equipment and materials that was needed. The next thing to be done was to write down the hypotheses for each temperature that was going to be use. The beets were all cut per the directions on the lab. The beets were then rinsed for two minutes in order to rinse away any dead cells. The beets were then laid on a paper towel to dry a little and the beakers were all labeled while the beets dried. All the beet...
