Paper type: ReportSubject: Science. Kinetic energy, a root of energy stored in cells, causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration.

Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water likely. Water potential is the measure of free energy of water in a solution. A living system also contains an active transport to make movement of particles like ions that move against their concentration gradient.

The energy source ATOP is used during this process to move the particles across the cell membrane. This experiment takes place to measure the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane, allowing larger molecules to pass through, but slowly. Dialysis is the movement of a solute through a selectively permeable membrane. When the two solutions on either sides of the membrane re equal and no net movement is detected, the solutions are isotonic.

This means that the solutions have the same concentration of solutes. If two solutions differ in the concentration of solutes that each has, the one with more solute is hypersonic. The solution that has less solute is hypotonic Apparatus: Experiment 1: Diffusion 1. Elodea plant 2. Zipper plant 3. Hypotonic solution 4. Hypersonic solution 5.

Don't use plagiarized sources. Potassium Africanized 3. Slides 4.In this study, we tested the validity of osmosis in artificial animal cells. Osmosis is the diffusion of free water across a membrane. The purpose of the study was to calculate the rate of osmosis in artificial cells containing different concentrations of sucrose and water.

We studied the rate of osmosis in artificial cells by creating five different dialysis bags with different concentrations of both sucrose and water and calculating the cumulative change in weight ever 10 minutes for 90 minutes.

Our results for the artificial cells showed different concentrations moved from high to low concentrations- through hypotonic movement or hypertonic movement. Introduction The main purpose of this paper is to assess the rate of change with osmosis for different concentrations of sucrose in artificial cells. The forces that affect osmosis are the concentrations of solutes surrounding the cell or inside of the cell. Water will then move across the cell membrane and create a balance of water between the cell and its environment.

In order to calculate the average rate of change for our artificial cells, we must understand tonicity as the ability of a nearby solution to cause a cell to lose or gain water, depending on its concentration of non-penetrating solutes relative to solutes inside the cell.

The dialysis bags used in this experiment have membranes that are selectively permeable, which only allows particles specifically small enough to pass through. Hire a subject expert to help you with Lab Report Osmosis.

In a hypotonic solution, water goes into the cell because the solute is more concentrated inside the cell, while in a hypertonic solution, water moves out of the seller because the solute is more concentrated outside of the cell. We are testing the effect of osmosis on different concentrations of artificial cells by calculating the cumulative change in weight and the corrected cumulative changes in weight and by determining whether a solution is hypertonic, hypotonic, or isotonic.

We predicted that a dialysis bag holding tap water in a beaker also containing tap water is in an isotonic solution. This will result in isotonic solutions remaining at the same weight, hypotonic solutions gaining weight, and hypertonic solutions losing weight.

We tested this by creating the five different dialysis bags with different concentrations of sucrose in order to measure the weight change in grams of the bag after nine 10 minute increments. Methods and Materials. This experiment took place on Monday, February 6th, During this time, we tested the effects of different sucrose concentrations on the rate of osmosis in artificial cells we made with dialysis tubing.

We studied five different dialysis bags containing 10mL of different concentrations of tap water and sucrose. We began the experiment by soaking the dialysis tubes to prepare them for the sucrose concentrations they would be filled with. Each bag was clamped closed.

All the bags were weighed before being placed in their corresponding beakers in order to record their initial weight in grams. In the same manner in which the bags were placed in the beakers simultaneously, remove the bags every 10 minutes, and record the weight of each bag. This process should be repeated for at least 90 minutes in total. This data was analyzed by calculating the cumulative change in weight for each dialysis bag. This was done from subtracting the weight of each bag from the initial weight of the bag.

Doing so, allows the weight of each bag to be initially zero. For that, we must calculate the corrected cumulative change in weight. For each time interval of 10 minutes, we subtracted the change in weigh of bag 1 tap water from the weight of each bag at the specific time measure- this corrected any oscillations.

Results in The corrected cumulative change in weight due to osmosis from different concentrations of sucrose and tap water are shown in Figure One. This figure shows the weight change in grams for every interval of 10 minutes. Using the corrected cumulative change in weight eliminates bag 1 because its average rate of change will always be zero.

The purpose of this experiment was to determine the relationship between concentration gradients and the rates of osmosis. Using the corrected cumulative change, we can monitor the rate of change for each bag, and correlate the rate of change to the rate of osmosis.

These results prove that the direction of osmosis does directly affect the rate of osmosis. If the slope begins with a negative x value, the solution is indeed a hypertonic solution, that when surrounding a cell will cause the cell to lose water, moving from a high concentration to a lower concentration.

The slopes which begin with a positive x value demonstrate a hypotonic solution, which causes a cell to take in water.Abstract- Provides a clear and concise 1-paragraph abstract which summarizes the purpose, methods, results, and key findings. Introduction- Clearly states the purpose of the lab.

This is because psychologists and more generally most scientists write accounts of their studies using a standard format, which makes explicit certain aspects of the study. There are two main reasons for doing this: 1 Ease of communication: it is easier to find what you want from a study if it is written in the standard format. This information must be provided in detail.

It should be added that many professions now include the skills of technical report writing, which requires clear, direct and concise expression, the ability to summarize and present data, and the ability to form hypotheses and draw valid inferences. Learning to write laboratory reports will provide you with a valuable and transferable skill. This guide tells you about the structure and style that is required for a psychology laboratory Both diffusion and osmosis are forms of movement that are part of passive transport dealing with cell membranes.

Diffusion is where the solutes move from an area of high concentration to a low concentration.

Lab Report Osmosis

Water goes through the cell membranes by diffusion. Osmosis is specifically the movement of water through membranes.

Since osmosis and diffusion are both part of passive transport, this means that they do not require energy or pumps. There are different environments created due to diffusion. There are hypotonic, hypertonic, and isotonic environments. Hypotonic is when the solution has a lower solute concentration compared to the water potential.

The hypertonic solution has a higher solute concentration and lower water potential. In an isotonic solution, there is no net movement and there is an equal concentration of solutes and water. In our labwe modeled diffusion and osmosis with a hospital scenario.

It is important for an IV solution to have salts in it so the water and solute can be equal to create an isotonic environment. Introduction The reason of this experiment was to identify the properties and effects of osmosis. Osmosis can be defined as the diffusion of water through a selectively permeable membrane.

Osmosis is a type of diffusion. Diffusion is when molecules move from an area of higher concentration to an area of higher concentration.

The three types of concentrations are hypotonic, hypertonic, and isotonic. When in comparison to another solution, a hypertonic solution has a lower concentration, a hypertonic solution has a higher concentration, and an isotonic is when the two solutions have an equal concentration. The experiment tested the relationship between the concentration of an egg and solutions of different concentrations.

The hypothesis is that an egg placed in distilled water will gain mass while an egg placed in syrup would lose mass. Methods To perform the experiment gloves and safety goggles were obtained.

Two decalcified eggs were also obtained from the teacher. Using an electronic scale, the initial mass was measured and recorded of each egg.We use cookies to give you the best experience possible. Words:Paragraphs: 4, Pages: 2. If the solution has a higher water potential than he potato cores, there will be net movement of water into the potato pieces.

Therefore, potato cores in less concentrated solutions will gain more weight than the potato cores in more concentrated solutions. Null hypothesis: Different sodium chloride concentrations in solutions have no effects on the mass of the potato cores.

Type of potato All the potato pieces come from potatoes bought at a store, packaged together. Initial sizes of potato pieces Measured before putting the pieces into the solutions with a ruler in mm and an electronic balance in gram. Temperature of the solutions All the beakers were kept in the same place, so the solutions experienced the same conditions. Size and material of the beakers The ml beakers were made of glass. Duration of time the potato is left in the solutions The potato pieces were left in the solutions overnight, approximately 10 hours.

Background Information Osmosis can be defined as the movement of water across a semi-permeable membrane from a region of high water concentration to a region of low water incineration. The semi-permeable membrane allows small particles through it but does not allow large particles such as sodium chloride.
