objective of this experiment was to test the effect of a specialized type of diffusion called osmosis‚ “which involves in selective transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal

How Does Salinity Effect Osmosis in Plant Cells? Introduction Osmosis is a type of diffusion but is the movement of water molecules in and out of the cells from a high concentration to low concentration through a semi permeable membrane. The aim of the experiment is to investigate the effect the salinity of solutions has on the process of osmosis and net weight gain/ loss by potato cells. This would be done by using similar size potato cubes and covering them with different concentrations of saline

Background Information Osmosis is the procedure where water or different types of liquids move through a semipermeable membrane. This type of passage is considered as simple diffusion where no energy is required. This means that the liquid will have

In the article‚ " The Egg and the Sperm" by Emily Martin‚ the author attempts to shed light on the gender stereotypes hidden within the scientific language of our biology textbooks. I found this article to be very intriguing because‚ as a nursing student‚ I’ve been exposed to many medical and biology textbooks and it has never occurred to me that cultural beliefs could influence how a biologist described their discoveries. I had no idea that within the scientific accounts of reproductive biology
