Domesticus Egg Osmosis Lab Report

The data in Figure 1 supported both our hypothesis and our predictions. The solute concentrations affected our model organism the Gallus gallus domesticus. The weight of the G. gallus domesticus egg has a greater decrease in mass when added to a higher concentrated solution than a lower concentrated solution. The data also supported the prediction that the mass of the G. gallus domesticus egg in 10% NaCl will weigh less than the G. gallus domesticus egg in the 1% solution. Diffusion and osmosis play an important role in moving solutes and water from high concentrations to low concentrations until equilibrium is reached. In both the 5% and 10% solutions the mass of the G. gallus domesticus egg decreases in mass and then slowly starts to increase in weight until inside the cell and the outside solution are in equilibrium. The decrease in mass is characterized by being placed in a hypertonic solution since the solutes of NaCl are greater on the outside of the cell therefore the water from the inside of the G. gallus domesticus egg will flow through the semi-permeable membrane to the outside in order to attain equilibrium.
The results of this experiment were expected with the help of having background knowledge that diffusion and osmosis will always flows from high concentrations to low concentrations until equilibrium is reached and without the assistance of any energy. …show more content…
gallus domesticus egg be if the experiment lasted a couple days. How the masses of the G. gallus domesticus would be affected when placed a 15% NaCl solution? In order for a more reliable evidence this experiment would need to be tested with more G. gallus domesticus egg in order to have more comparison. In an idea experiment there would need to be around 10 G. gallus domesticus eggs in each group over the course of a week. This will produce a variety of data which will lead to more accurate
