Mayra Guadalupe October 29‚ 2012 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

could be overserved that their was no physical or chemical effect on the tonoplast membrane. The alternative hypothesis in this laboratory experiment‚ was that if the beets were exposed to acetone‚ the tonoplast membrane will be able to release betacyanin a red dark color.

The kind of proteins present in the membrane is important in controlling solute movement across the membranes. As an experimental model‚ red beet roots will be used to study membrane integrity. Red beet roots contain a large amount of a reddish betacyanin pigment‚ called betanin. This pigment is synthesized in the cytoplasm‚ and then transported across the tonoplast against its concentration gradient where it is accumulated and stored in the vacuole. In healthy cells the pigment remains in the vacuole

be controlled‚ especially the biological material (a confounding variable). Background information Fresh beetroot tissue is used in this experiment because it contains a dark red pigment within the vacuole of its cells. The dark red pigment is betacyanin. There is also a yellow pigment called betaxanthin in the vacuole. The pigments are retained in the vacuole by a selectively permeable membrane called the tonoplast. It has a similar fluid-mosaic structure to that of the plasma membrane with protein

plant vacuole of plant cells contains water and solutes‚ including water-soluble pigments. Its membrane‚ the tonoplast‚ is normally poorly permeable to water. The central plant vacuole of the root cells of beet contains a water-soluble red pigment‚ betacyanin‚ which gives the beet its characteristic color. Since the pigment is water-soluble and not lipid soluble‚ it remains in the vacuole when cells are healthy. If

number of molecules that are able to leave the cell and come into the solution will increase‚ however I think that there will be appoint at which the amount of molecules coming out will remain constant. Red beet tissue contains large amounts of betacyanin‚ a red pigment‚ located in the large internal membrane vacuoles. When the membrane is damaged‚ the pigment can cross the vacuole membrane and cell membrane. Since pigment is water soluble and not lipid soluble‚ it remains in the vacuole when the

membranes have a variety of specific functions. One type of membrane-bound vacuole found in plant cells‚ the tonoplast‚ is quite large and usually contains water. In beet plants‚ this membrane-bound vacuole also contains a watersoluble red pigment‚ betacyanin‚ that gives the beet its characteristic color. Since the pigment is water soluble and not lipid soluble‚ it remains in the vacuole when the cells are healthy. If the integrity of a membrane is disrupted‚ however‚

Natural Benefits of Drinking Beet Juice: Drinking beet juice can lower blood pressure levels in just a few hours. One study found that drinking one glass of beet juice lowered participants’ blood pressure by an average of 4-5 points. This can be attributed to the naturally occurring nitrates in beets‚ which are converted to nitric oxide in the body. This then relaxes and dilates the blood vessels to improve blood flow and lower blood pressure. Many illnesses and chronic diseases begin with inflammation

The effect of temperature on the permeability of cell membranes Introduction For my coursework‚ I intend to assess how temperature affects the plasma membrane of a cell. For this I will use the cell of a beetroot. Background What is a cell membrane? The cell membrane‚ also called the plasma membrane is a semipermeable lipid bilayer which is the surface of all cells that surrounds the cytoplasm. The membrane is called a bilayer as it has a double layer of phospholipids. Within the cell membrane
