In this experiment, we got to personally witness and participate in the process of capillary action in plants, demonstrating both cohesion and adhesion. Solvency was demonstrated within the dye dissolving in water. 

Facilitated diffusion occurs with a channel protein facilitates the movement of large or charged molecules into/out of the cell. This is done so it does not disrupt the phospholipid bilayer, as it cannot pass through without this channel protein. As shown in the model, the phospholipid bilayer contains hydrophillic heads (the black plates) and hydrophobic fatty acid (bent is unsaturated) tails.

This was the section of the fluid mosiac model that me and my teammates constructed. Simple diffusion is the flow of small, uncharged molecules (oxygen shown by the blue diatomic spheres) through the phospholipid bilayer (as constructed here) of the cell membrane. Because it is natural and along the concentration gradient, it doesn't require energy, making it passive.

This part of the cell membrane focuses on the flow of molecules against the concentration gradient. This occurs by using energy (ATP) to facilitate diffusion from area of high concentration to low concentration. This is done to maintain homeostatsis within the cell while outside concentration gradients differ. The integral protein shown helps move the substances agsinst the concentration gradient.

This experiment details the process in which we placed the same egg in different hypotonic and hypertonic solutions and measured & compared its reactions. This demonstrates the principles of osmosis and how water moves across semi-permeable membranes.

Our subject for this test of osmolarity and tonicity was gummy bears. These bears were tested in two solutions per group, each with different solute concentrations. In one cup, we had our control group with 100mL of pure water. The other had the same, but with an addition of a certain  amount (in grams) of the organic compound NaCl (salt).

Within this experiment, our test subject was carrots. We aimed to measure the movement of water across membranes when placed in hypotonic vs hypertonic solutions. We wanted to see exactly how being placed in these solutions with different concentrations or water vs solute affects organic life.
