Planning AIM Beetroot cells contain a red pigment‚ which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell surrounds it. The outer of the cell is also surrounded by a membrane‚ which again helps contain the pigment inside the cell. In this experiment I aim to find out the relationship between the leakage of red pigment from a beetroot cell and the surface area. To do this successfully I will need to alter the surface area of the beetroot cells accurately and then

Embryonic vs. Adult Stem Cells - Why Jean Swenson Doesn’t Support Embryonic Research and Why An Audience Would Listen As science becomes more and more advanced‚ there are many more ways to combat illnesses. Some of these are more successful and widely known‚ but one of the more controversial is stem cell research. In the article "Embryonic Stem Cell Fairy Tales"‚ Jean Swenson attempts to educate the public on why she believes many are prone to believing that embryonic stem cells (which have not been

TEMPERATURE AND SDS CONCENTRATION ON THE STRUCTURE OF BEETROOT CELL MEMBRANES. Introduction Cellular Membranes or cell membranes are biological membranes that separate the interior of a cell from the outside environment. Cell membranes are selectively permeable to ions and some molecules and control the movement of substances in and out of the cell. (Danyk‚ 2013/14) Cell membranes separate and organize chemicals and reactions within cells by allowing selective passage of materials across their

Purpose: Examine the role of the cell membrane in the cell by disrupting its function using temperature (Biology 107 Laboratory Manual 2014). This will improve the general understanding of optimal growing temperatures and the breakdown of the cell membrane Procedure: Betacyanin solution of a known concentration was diluted to create a dilution series‚ then placed in a spectrophotometer set to 525 nm. The absorbance of the dilution was used to create a standard curve for betacyanin. Discs of living

Embryonic stem cells The term "stem cell" in Websters dictionary defines it as "An unspecialized cell that gives rise to differentiated cells"‚ which is a fancy way of saying "stem cells can be used to copy and turn into any other type of cell". To understand Embryonic stem cells‚ we must go back to the Discovery of stem cells in general. Stem cell research first dates back to the late 1800’s‚ when scientist first observed evidence of cells able to produce other cell types. There was a gap in

Embryonic stem cells (ES cells) which are stem cells that are derived from the embryo and are capable of creating other cell types in the human body can assist the affected individuals maintain homeostasis in their bodies. Parents have the right to agree to the use embryonic stem cells as it will ensure wellbeing of the new born baby. However there are moral‚ ethical and religious matters which lead to people being against the use of ES cells. The state of “homeostasis” is the

The capability to revert blindness‚ cure diabetes‚ let paralyzed people walk again‚ replace deficient organs with newly grown ones and cure blood diseases are a few of the many potential functions of stem cells. A stem cell is an unspecialized cell that can develop into many different cell types in the body during early life and growth it also has the ability to divide essentially without limit. Unlike mature cells‚ which permanently have the same function‚ stem cells can both
