The step by step process was used by the software so that we could see the different kinds of reactions. According to the data found, we found that with high molecular weight compounds are too large to penetrate the molecular weight cut off pores and no simple diffusion can occur.

Osmosis is the dispersion of water. Our cells are capable of absorbing nutrients because, the cell membrane is selectively permeable (some molecules can effuse freely through the membrane while others cannot). In this experiment we used dialysis bag as a model of the cell membrane. Our hypothesis was that the glucose will diffuse out of the membrane into the beaker filled with iodine solution. To demonstrate dialysis tubing we used water, starch and iodine. When starch and iodine react together…...

Kinetic energy, a root of energy stored in cells, causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water likely. Water potential…...

A spectrophotometer will be used to measure this variable by measuring the absorbency value of the beautician in solution after each treatment. The results of this study will show the necessary temperature to keep the vacuole intact. It would influence common agriculture practices by indicating a more ideal environment setting and techniques. At the same time, it would allow scientists to have a better understanding of cell structure and functions. We hypothesize that beet cells in a high temperature environment…...

I think that the increase of the temperature on the beetroot will affect the diffusion of the colour dye in the beetroot. The colour dye is held together by the membrane structure and this maintains the red rich colour in the beetroot. I believe that with the increase of temperature applied onto the plasma membrane, the structure of the membrane will become damaged and the membranes of the protein will eventually denature. Scientists know that cell membrane have the following…...
