Effect Of Sucrose Concentration On C Melo

7. Explain how incubation plant tissues in a series of dilutions of sucrose can give an

As the Concentration of the Sucrose Solution decreases, the more the potato’s mass increases. This is due to the solution being hypertonic. So, as the solute concentration gets lower, the potato’s water concentration will get higher, therefore more water particles from the solution will absorbed by the potato. Some changed very little in mass because the concentrations of the H2O molecules in the potato and outside the potato were equal. This equality in concentration is called Isotonic.

We know that water will move through a membrane from more free water to less free water. The higher the solute concentration is, the less free water there is. All of the sucrose solutions are being put in pure water, but the ones with the most sucrose will need the most water to diffuse inside and bring the free water levels to equilibrium, and the ones with less will need less water to diffuse.

Determining the effect of varying sucrose concentration on the rate of anaerobic cell respiration in yeasts

Osmosis is defined as the tendency of water to flow through a semipermeable membrane to the side with a lower solute concentration. Water potential can be explained by solutes in a solution. The more positive a number is more likely it will lose water. Therefore should water potential be negative the cell the less likely it will lose water. In using potatoes the effects of the molarity of sucrose on the turgidity of plant cells. According to Clemson University, the average molarity of a White potato is between .24 M and .31 M when submerged in a sorbitol solution. This experiment was conducted with the purpose of explaining the relationship found between the mass in plants when put into varying concentrations of sucrose solutions. Should the potatoes be placed in a solution that contains 0.2M or .4M of sucrose solution it will be hypotonic and gain mass or if placed in .6M< it will be hypertonic and lose mass instead. Controlled Variables in this lab were: Composition of plastic cups, Brand of Russet Potatoes, Brand of Sweet Potatoes and the Temperature of the room. For independent variable that caused the results recorded it was the different Sucrose concentrations (0.0M, 0.2M, 0.4M, 0.6M, 0.8M, 1M). The dependent variable was the percentage change from the initial weighs to the final. The cup with .4 molarity was the closest to an isotonic solution and was used as the control group for the lab. Water potential is the free energy per mole of water. It is

Osmosis is a special type of diffusion where water molecules move down a concentration gradient across a cell membrane. The solute (dissolved substance) concentration affects the rate of osmosis causing it either to speed the process up or slow it down. Based on this, how does different concentrations of sucrose affect the rate of osmosis? If sucrose concentration increases in the selectivity-permeable baggies, then the rate of osmosis will increase.

Sucrose is a type of sugar found in many plants, and is often used as an energy source for a process known as cellular respiration. This process breaks down of sugars like sucrose in the presence of oxygen to release energy (Miller and Levine 222). It involves many different parts of which the main include breaking down food molecules, releasing chemical energy, and then converting this energy into usable energy for the body. Thus, making it an essential practice of all heterotrophs, as energy must be produced for survival A heterotroph is an organism that obtains energy from the foods it consumes (Miller and Levine 68). An example of a heterotroph is yeast, and it cannot survive without its food sources of sugars like fructose, glucose, and sucrose, as they are needed as products for cellular respiration. Yeast is seen and used in our everyday lives from baking bread to fermenting beer, but we rarely appreciate its intricacies and the processes that create and sustain it. Therefore to look deeper we must observe how it utilizes the environment around it and how the yeast is affected.

From the graph, R2 can be extrapolated from the y-axis and the corresponding value on the x-axis (the point of intersection on the curve) gives the concentration of the unknown solution.

In this study we constructed we researched whether different sucrose concentrations affect the rate of osmosis. In order to do this, we constructed artificial cells out of dialysis tubing filled with 20% sucrose and 40% sucrose and weighed them every 10 minutes for 90 minutes. In doing so, we concluded that the higher the sucrose concentration, the faster the rate of osmosis.

As we can see in Figure’s 1.2 and 1.3, when there was no sucrose solution, the potato increased in weight. This is due to the fact that the sucrose solution was hypertonic in comparison to the potato slice. Through osmosis, the solution moved along the concentration gradient and into the potato slice making it hypotonic. When there were higher concentrations of sucrose solution, the potato decreased in weight. This is due to the fact that the potato was hypertonic in comparison to the potato. Through osmosis, sucrose from the potato moved along the concentration gradient out and into

Once the hour was over, the potato slices were removed from the solution, dried off in a paper towel, and weighed once again. In the 0.0, 0.1, and 0.2 M of sucrose concentrations the final mass of the potato increased. Therefore H2O enters the potato cell because the solution is hypotonic. In the 0.3, 0.4, and 0.5 M of sucrose concentration the final mass of potato decreases. The solution is hypertonic which causes H2O to exit the potato cells through the semipermeable phospholipid bilayer. The results prove that the different molarities of concentration affect the mass of the potato in different ways; the mass of potato either increased or decreased depending on the molarity of sucrose concentration.

This lab investigates the effects of Sucrose concentration on cell respiration in yeast. Yeast produces ethyl alcohol and CO2 as a byproduct of anaerobic cellular respiration, so we measured the rate of cellular respiration by the amount of CO2

Concentration of sucrose is higher because every time we add up time there is a weight difference. As we can see, in the above graph that every sucrose is getting heavier every time we add up 15 mins but 1.0m source does not have that much weight difference like other sucrose. The weight difference from distilled water to 0.8 sucrose is rapidly changing but there is no weight difference between 15 mins-45 mins in 1.0 sucrose. My hypothesis does not support statement because the weight didn’t change in 1.0 sucrose like other did. The data lead the researcher accept. Yes, there was unexpected results because my hypothesis was that every sucrose supposed to change their weight concentration. There were not any things that happened during the experiment

If the amount of sucrose increases, then the rate of osmosis will also increase. When distilled water is placed in a dialysis bag acting as a semipermeable membrane and placed into distilled water there should be no weight change because the concentration is balanced both inside and outside the bag. When a solution if 15%, 30% sucrose in a dialysis bag and that bag is placed into distilled water it should gain weight because the water will diffuse from a high concertation to a low concertation. But when distilled water is placed in a solution of 30% sucrose it should lose weight because the sucrose solution will diffuse into the distilled water because there is more concertation inside than outside of the bag. Diffusion is where a substance

If the solution contains only sucrose then the osmotic pressure will increase substantially. This would represent a hypotonic solution because more water molecules are entering the cell meaning the solution contains no invertase. If the osmotic pressure has a slight increase than the solution contains sucrose and invertase due to the rate of the sucrose being broken down, however the cell will overtime begin to shrink. If the osmotic pressure remains close to the same than the solution contains no sucrose, containing only water and invertase. We predicted that because the height of the fluid in the osmometer tubing was increasing only a little bit our blue solution was hypertonic and contained invertase and sucrose. The invertase was able to break down sucrose into glucose and fructose which were small enough to be able to leave the cell membrane. This would reflect a hypertonic solution. We predicted this would cause the cell to shrink in size and the height of the fluid would never increase.
