Essay

tissue layer structure and how it relates to its function using living common beet cells.

Introduction
Membrane holds content in place and acts as a selective barrier, regulating movement of material into and out of the cell. Membrane structure and function is important to biology because it helps investigate the essences of stressful experimental treatments such as the effects of frost and low temperatures on living organisms. It also helps to investigate the excogitation about membrane structure using a ``sandwich`` model, and gain experience using a spectrophotometer. Membrane has a phospholipid bilayer which has hydrophobic (non polar) tails and hydrophilic (polar) head. The cell has a vacuole contact by a membrane called the tonoplast. It`s also encircled by another membrane, the plasma membrane. When these cells are equipment casualtyd the betacyanin which is a red pigment in the beet cells will let on out and produce a red color in the water surrounding the beet.
We are going to subject discs of beet root to temperature and lipid dissolving solvents and assess the amount of damage to the cells via measuring the amount of betacyanin leaked from the cells. Hypothesis (null): there will be no effect of temperature (independent variable) on membrane damage (dependent variable) in beta vulgaris i.e.



cell type.
Alternative: the will be an effect of temperature on membrane damage in beta vulgaris.
Materials & vitamin A; Methods
Spectrophotometer is used to measure the amount of betacyanin leaked from the cell. Using a shave blade and a ruler measure and cut 9 discs each 5 mm long. Rinse all discs in a larger beaker with a cool running tip off water for 5 minutes. Fill 7 large with 10 ml of distilled water and label each test tube-shaped structure with the number for the different temperature treatments. Using forceps harbour a pre-cut flash-frozen beet root provided by your instructor and place in the appropriate labelled test tube.
For the next treatment, gently take another beet disc and place...If you want to get a full essay, order it on our website: Ordercustompaper.com
