Water Potential Osmosis Experiment

743 Words3 Pages

This experiment is an attempt to investigate the amount of water potential across root storage plant species. The root storage plant species that shall be used are the carrot and the potato and the method that shall be used is known as Chardakov’s method. Water potential is the tendency of water to enter or leave a cell. Water moves from an area or region of low water potential to an area of high water potential. It is important to note that the highest water potential is 0(the water potential of pure water) and the other water potential values are in negative numbers .
There are three major components of water potential and one of them is solute or osmotic potential (the amount by which water potential is reduced by the presence of solute …show more content…

This conveys that sucrose concentration shall affect water potential, therefore the higher the sucrose concentration, the lower the water potential.
This is how osmosis is linked to water potential and why experiments testing osmosis can be used to create methods to find and/or test water potential within plants. In addition to this, concentration of sucrose in a solution and in a plant cell or plant tissue shall have an effect on water potential.
The experiment shall use several concentrations of sucrose solution and a substance known as Methylene blue. A piece of potato/ carrot shall be placed in a boiling tube and the solution shall be poured into it. This tube shall have Methylene blue added into it. After incubation some of this solution shall be taken out with a pipette and inserted into a separate boiling tube containing the same sucrose solution however this solution shall be known as the pre-incubated solution. The drop shall be watched so as to see if the density of the water and concentration of sucrose has increased or not, displaying the water

The cell membrane is semi-permeable, meaning some substances can pass through but others cannot. Osmosis is the diffusion of solvent molecules (e.g. water) across the membrane from an area of high concentration to an area of low concentration (Lopez & Hall, 2022). When the fluid on the extracellular side of the cell has a higher concentration than the cytosolic side it is hypertonic. When it is lower than the cytosolic side it is hypotonic. When both sides of the membrane have equal concentrations, they are isotonic.

Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

The constant movement of solutes and water across cellular membranes is an overarching concept that helps to maintain cells’ growth and dynamic homeostasis. Water potential, the measure of the relative tendency of water to move from one area to another, takes into consideration the concentration of free water molecules. It is calculated using the following formula: water potential (Ψ) = pressure potential (Ψp) + solute potential (Ψs). The water in an organism moves down a concentration gradient, from an area of high water potential to low potential.

It is intriguing to think an inanimate plant has evolved to the point that it can quickly react to the stimulation of touch. The most common explanation among environmentalists and ecologists is that is a quick alteration in the turgidity of the plant cells. That means there is a change in the pressure of water located inside of the cells. These cells are located in the lower part of the midrib. Although it is not as simple as stated, it is true that the lower midrib cells consume more water.

The answer to our question in our introduction is that duckweed plants grow better in medium amounts of water. In this case, specifically 500 ml of water. Our hypothesis, however, was incorrect, for we believed the duckweed would grow better in the small amount of water. We had many errors in our experiment. For example, when we had the beakers on the window sill, the sun had evaporated some of the water.

The lab that I did was elodea leaf lab, where me and my partners have to gets a blank glass, take a little leaf out of the water, and put a drop of its water into the glass before putting the lid on. After carefully observed the leaf by using the x65 lens, we puts a drop of salt into the leaf and closed the lid to see how the chloroplasts changed under the microscope. We were basically analyzing the changing of the chloroplasts shape after we puts the salt solution into the elodea leaf. The purpose of our lab was to see how salt solution can affect the elodea leaf cell.

For this lab I will be using water and sucrose to demonstrate the rate of osmosis. In this lab I will be exploring how temperature impacts the rate of osmosis by placing pieces of potato of equal size in solutions of different temperatures and observing the change in mass of potato after a given period of time. The change in mass will indicate the rate of osmosis.

By using the same mass of potato slices and putting them in different concentration of solutions for a specific amount of time will tell us how the concentration changes the mass of the potato slice. Therefore changing the rate of osmosis. Hypothesis: I predict that, if the piece of potato was put into a solution that has a high concretion of sucrose then the potato slice would lose mass as it would lose water from its cells because the water is moving out of the cell from a high concentration to a low concentration of water through a semi- permeable membrane. The cell is hypotonic and the solution is hypertonic.

of water varying slightly from person to person. We consume water from drinking it and also from the food we eat such as watermelons. We also get a tiny percentage of water given out through the process of respiration. Water is a universal solvent. Water in our body acts as a solvent for solutes such as amino acid, glucose, urea, lipids (non electrolytes) and electrolytes (which break up into ions) such as Na+, K+ to be dissolved in.

 Two of the same types of plants were used, in order for the results to be reliable.  One of the plants was labelled DISTILLED whereas the other was ACIDIC, so the results don’t get mixed.  The DISTILLED plant was used as a controlled variable, where normal spring water was used (pH 7.3)  The ACIDIC plant was the one the experiment had taken place on, this was where lemon water was used (pH 2.0)  Throughout the experiment pictures were taken, so one will be able to notice the colour change on the acidic plants, as it had started to slowly die. With both plants you are able to notice that they had both started to grow flowers, but more the spring watered plant than that on the lemon juice watered one.  The results of the plant growth was recorded to we would be able to notice the amount it had grown, this would be the water compared to lemon juice.

Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
