Osmosis And Diffusion Lab Report

Osmosis and Diffusion are two important key concepts that helps the cell as a whole functional. Diffusion is simply the movement of a substance from an area that has higher concentration to an area that has a smaller amount of concentration. Osmosis is the total opposite of Diffusion; Osmosis consists of a solvent being able to pass freely through the membrane of a less concentrated solution to a higher concentrated solution.

Diffusion means to spread out, and in the process of diffusion it is actually spreading out the substances to make the molecule more proportionate. While in class the professor sprayed a can of Lysol and the students had to test the time it took for the smell to reach them, as one may know the people furthest away smelled

it later than the people that were closer to the vicinity of the can of spray when it was sprayed. Diffusion occurs throughout the human body significantly, with the absence of diffusion cells and tissues would become unhealthy and die off simply because they’re not gaining the proper nutrients that are essential for survival. One place where diffusion takes place is in the respiratory system, oxygen that human beings breathe in diffuses from the alveoli into the blood whereas the carbon dioxide that people exhale moves from the blood into the alveoli. In regards of the method the oxygen that is in alveoli level of concentration is held at a higher rate than the concentration of carbon dioxide.
In lab, the students did an experiment that was based on the moral understanding of osmosis.

In the experiment they had a cell and an environment (beaker). In the cell they placed “cytoplasm” in it and in the environment it was deionized water. They were testing to see if the water from the environment was able to move inside the cell, and make the cell enlarge, or if the water from the cell would leave to go into the environment. The students had to wait and watch the cell for an hour to see the result, the cell grew because of the process of osmosis. While doing this specific experiment the students discovered that the cell was permeable because it allowed the water to reside in it. Osmosis is constantly working in and out of the human body, for instance in the kidney. When a person has a bad kidney they have to go through kidney dialysis which helps the kidney get back on track with the original functioning. Osmosis plays a huge role in bringing the kidney organ to a more operational format because “Osmosis causes the metabolites to flow out of the blood, through the membrane, and into the dialysis solution…” Adam Cloe (2015) According to Cloe Osmosis is highly considered as a filter when it comes to the kidney because it does its best to cleanse the kidney and allow it to do its original job of receiving

blood.
In conclusion Osmosis differ from Diffusion in many way but in sorts they actually work together, “Osmosis is the diffusion of water across a semi- permeable membrane.” Vamsi Paluvadi (2014). The movement of molecules that occur in diffusion and osmosis are proven to be passive because they don’t require as much work to move around, the kinetic energy that are stored in the particles are what help them with the energy needed to be able to diffuse.
