Essay on Investigate the Water Potential of Potato Cells

Use Equal widths of potato core each time by using the same corer. This is important because if I used a different corer, the potato core might come out as a different width. This could be because of rust, or maybe even the thickness of the metal.

3. Explain your prediction for the effect Na+ Cl- might have on glucose transport. In other words, explain why you picked the choice that you did. How well did the results compare with your prediction?

5. Experiment: Click Reset. Check that the Solute outside is 10 and the Initial cell volume is 40%. To calculate the solvent concentration, divide the number of solvent particles by the total number of particles, and then multiply by 100. (Note: The Gizmo only displays the solute concentrations.)

Osmosis is the diffusion of water across a membrane to create an equilibrium between the levels of concentration of a solute both inside and outside the cell. In this case the solute will be sugar as the potato core will be immersed in sucrose solution.

After all results have been recorded, pour all of the solutions down the drain, rinse equipment and clean up the

The solution is stirred with a stirring rod and stopped as soon as the pink colour disappears.

The following hypothesis was made in regard to effect of the concentration gradient on the rate of diffusion: The higher the concentration gradient, the faster the rate of diffusion.

Water is essential for life as we know it on earth. It is used by plants

The Importance Of Water To Living Organisms Water is normally the most abundant component of any living organism. As most human cells are approximately 80% water and 60% of the human body is made up of it, it is extremely important in many different ways to both the survival and the well being of living organisms. Evolutionists believe that life probably originated in water and even today thousands of organisms make their home in it. Water also provides the medium in which all biochemical reactions take place. The importance of water to living organisms originates from its many properties including its solvent properties, its high specific heat capacity, its high latent heat of vaporization,

As I sat next to the loud river that was bursting out of the Sylvan Dam, I noticed the water was in an invariable battle with the rocks, crashing and thrashing against each other like medieval warriors scraping for land. I looked around the edges of the river to see the copiousness of colors from the trees contrasting the sinister blue water. The rapids put off a pleasant and dulcet sound that ultimately ended in me having to relieve some building pressure down the trail. After returning to my riverside view, I noticed that farther down the gleaming river, fish were jumping and flipping like delicious pancakes on a griddle. Making the split-second decision to fish, I sprinted to my 1999 black Chevy Silverado, unlatched the tailgate and snatched all of my waterproof fishing gear. Slipping on my Mossberg max 4 Camo Gander Mountain guided series waders is no easy chore. While looking like the most incapable human being ever I finally managed to slip on the foul scum smelling waders that I so dearly should have washed. Feeling like a professional mountain climber, I started scaling the steep inclement of the river bank. Stomping my insulated waders into the frigid dour murky water, I ventured my path out onto a construction of rocks forming a beautiful approach for spotting fish. I released my light green jointed shad Rapala from my St. Croix Legend Elite spinning rod and casted the shad into pooling backwater just off of my rocky approachment. Feeling the vibration of the shad through my rod, smacking against slime covered rocks and ripping through dense weedy areas. I felt aspirant to not get hung up on a rock resulting in a line break, I successfully retrieved my lure. After casting and reeling my line several times and just started zoning out, I was abruptly startled to hear a ruckus coming from the west side embankment. Glancing quickly back to the water to see where my lure was only to hear a loud splash coming from the same place where I first noticed the ruckus. Three deer, with golden brown fur coated enrolled into the water. Realizing that the leaders of the small herd were both doe’s and a younger buck eagerly followed. The buck had a nice six-point rack, with long tines and a wide spread. He kept his

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.

The hypothesis is that when cells are put in a solution with a different water potential than inside of them, cells will gain or lose water. If concentration of solution is the same, there will be no change in mass.

“Drinking water is like washing out your insides. The water will cleanse the system, fill you up, decrease your caloric load and improve the function of all your tissues.” – Kevin R. Stone --

First I gather all my materials needed for the experiment (see materials list). Second I peel and slice potatoes weigh each potato in grams. Get these slices to weigh the same in mass because if they vary to much in mass that could affect the results of the experiment. Third I place each potato in its own beaker. Fourth once the potatoes are placed in beakers I make sure to place enough solution to fully cover the potato. Each beaker should have a different amount of

This paper discovers the water budget for Berkeley, California in comparison to Terre Haute, Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters, where the majority of rain occurs and Terre Haute, Indiana where the rainfall is observed as consistently disseminated throughout the year evenly. This paper will also magnify geographic position, climate and elevation in contrast of the two cities that reflects the water budget outlined in Project 1: Water Balance defined in
