Effects of Temperature on Beetroot Cell Membranes

Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water, it is on the outside of the cell, the hydrophobic region is the inside of the cell where its protected from H2O. The cell membrane’s outer surface lets larger molecules into the cell. The inner surface deals with proteins that are important for development and cellular function. The cell membrane contains specific proteins and lipid components that enable it to perform its roles for the cell or organelle. A cell membrane can perform many different

After 90 seconds the test tube was removed and the water in the test tube was tipped out. 10ml of tap water was then added to it and then left to stand in the test tube rack.

The beaker was then heated to 65c. The burner was then turned off and the water’s temperature was left to rise to 70c. 5 beetroot slices where then added to the test tube labelled 70c, then water was added to the slices just to cover them. The 70c test tube was then placed into the beaker with the water’s temperature at 70c for 90 seconds. After 90 seconds the test tube was removed and the water in the test tube was tipped out. 10ml of tap water was then added to it and then left to stand in the test tube rack.

The beaker was then heated to 75c. The burner was then turned off and the water’s temperature was left to rise to 80c. 5 beetroot slices where then added to the test tube labelled 80c, then water was added to the slices just to cover them. The 80c test tube was then placed into the beaker with the water’s temperature at 80c for 90 seconds. After 90 seconds the test tube was removed and the water in the test tube was tipped out. 10ml of tap water was then added to it and then left to stand in the test tube rack.

After 30 minutes the test tubes were shook and then held against a white background in a well lit room. The colour of each solution was recorded.
