An investigation to find the water potential of potato and carrot tubers in a sucrose solution‚ of concentration 0.00 – 0.50Mol‚ over a 24 hour period Interpretation Written Communication C1 From our graph it can be seen that the concentration of sucrose solution is 0.18 M at 0% change in mass for the potato and 0.355 M at 0% change in mass for the carrot. I will use these values to find the solute potential by using the calibration graph. I will work out the water potential by using the

Chickens farmed for meat are called broilers‚ whilst these farmed for eggs are called egg-laying hens. In total‚ UK alone consumes over 29 million eggs per day. Some hens can produce over 300 eggs a year. The majority of poultry are raised using intensive

I. Research Question What are the effects of different sucrose concentrations on potato stripes which have been submerged in a range of solute sucrose concentrations. II. Background Information Osmosis is one of the four methods of moving particles across membranes along with simple diffusion‚ facilitated diffusion‚ and active transport. Water is able to move in and out of most cells freely. Sometimes the number of water molecules moving in and out is the same and there is no net movement‚ but at

concentrations of solute is isotonic. A solution with a higher concentration of solutes is hypertonic and one with less concentration of solutes is hypotonic. “The term osmolarity is used to describe the number of solute particles in a volume of Gluid. Osmoles are used to describe the concentration in terms of number of particles.” It

Osmosis and Water Potential in Potato Tissue Melanie Shadish‚ Rob Harris‚ Patricia Tellekamp Water appears to cross the differentially permeable membrane of potato cells by a process called osmosis. The measure of the energy involved in osmosis is called water potential. Since water must lose energy as it moves by osmosis‚ water must move from

Potato Core Experiment In this experiment we estimated the osmolarity of potato tuber tissue by submersing different potato cores into sucrose solutions of 0.0-0.6M‚ and weighing the potato. We concluded that the osmolarity of the potato was about 0.4M since the weight of the potato did not change after it was incubated in the solution with 0.4M. We also found that the potato was hypertonic to sucrose solutions of 0.0-0.3M and hypotonic
