Diffusion

Bahliawah Abstract Throughout the process of this experiment, chicken eggs were used to test how well certain solutions would be absorbed. The objective was to determine the rate and direction of osmosis into and out of cells according to their diffusion gradients. During this experiment eggs were rolled on paper towels to blot the excess liquid and then weighed. They were then placed into one of six solutions immediately afterwards. In 15-minute intervals, the eggs were blotted and weighed…

system. There is a constant movement of various molecules in and out of the cell that brings nutrients in and brings waste out. This movement of particles in and out of cells is based around osmosis. It is written in the Lab Manual (2014) “Osmosis is diffusion of water across a differentially permeable membrane” (p. 97). In this experiment, dialysis tubing, a type of differentially permeable membrane which only lets water molecules through, was used to create bags used to model cells. Four bags…

Eggsperiment Purpose Is an egg similar to a human cell? Hypothesis If the egg is put in milk, then the shell will grow back. According to Mama Natural, “High-quality eggshells contain 27 essential microelements but they’re mostly composed of calcium carbonate, a form and structure that’s very similar to our bones and teeth.” Also, according to My Plastic Free Life, “eggshell powder contains roughly 400 milligrams of calcium per gram.” Since the milk I use, 2% Fat, has 295 milligrams in one cup…

solution for example. The water inside the cell is hypotonic because it has less of the solute (alcohol). The solution in the cell's environment has a higher concentration than the inside of the cell which means that is hypertonic. This means that diffusion of water (osmosis) will occur. The water inside the cell would diffuse to the outside of the cell when there is a higher concentration of alcohol because there is a lower concentration of water outside the cell. The water would diffuse…

Buddhism is one of the most important Asian traditions. How could it be that Buddhism, a totally foreign religion, successfully established itself in China? There are a plethora of reasons why this type of diffusion occurred. I will be providing the historical overview of the introduction to Buddhism and how it was developed once it spread through China. It begins with one man Gautama Siddhartha, (563-483 B.C.E), the founder of Buddhism, even though he was contemporaneous Confucius. He was…

In this experiment I attempted to created and study the affects of a egg in a hypertonic and hypotonic solution. To conduct this experiment I used the following materials: cups, eggs, vinegar, corn syrup, spoons and food coloring. To begin the experiment I placed three eggs in vinegar to dissolve their shells, leaving behind a thin membrane that allowed water to pass in and out of the eggs. The water molecules enter inside the eggs and the eggs begins to swell. Once the eggs have sat in the…

to be selectively permeable which means that the cell allows only certain objects and substances in and out of the cell (McKinley, O’Loughlin, & Bidle, 2015). Substances are moved across the cell membrane through a process called diffusion. Osmosis is a type of diffusion that involves the movement of water across the cell membrane from an area of low concentration to an area of high concentration (McKinley, O’Loughlin, & Bidle, 2015). There are three types of concentrations of solutes: isotonic,…

Observing Osmosis INTRODUCTION Osmosis is the “diffusion of water across a selectively permeable membrane” (Raven et al. G-16). In this experiment, dialysis tubing was used to mimic the selectively permeable membrane to show what osmosis does when placed in different solutes. We filled dialysis tubes fill with different percentages of solute and placed them in beakers full of a different solute. Through this experiment, I saw what happens when the solution becomes hypertonic, hypotonic, and…

Active and passive transport move oxygen, water, and nutrients into cells and remove waste. Active transport requires a chemical energy because it moves from lower concentration to areas of higher concentration. It uses ATP to pump the molecules against the concentration, which requires cellular of solute. Passive transport moves from areas at a higher concentration to low concentrations, so it doesn’t require energy. Active transport takes place in the membranes of both the mitochondria and…

1959702695 Osmosis is a type of facilitated diffusion where water molecules move from high concentrations of water to low concentrations of water through a selectively permeable membrane. Osmosis is a way for water molecules to create equilibrium between a cell and its environment. For example, if the cell is a hypotonic solution and its environment is a hypertonic solution, then water will naturally diffuse to its environment to create equilibrium. The guiding question for this experiment was,…
