data (attached) gathered from this lab‚ the approximate concentration at which the solution and potato cytoplasm is isotonic is 0.4 mol/L. I can therefore conclude that the approximate solute concentration of potato cytoplasm is also 0.4 mol/L. This is because the concentration of potato cytoplasm never changed throughout the experiment‚ but the sucrose solution did. Seeing as isotonic means both concentrations are equal‚ I can conclude that the potato cytoplasm was always around 0.4 mol/L. 3.

that in a hypertonic solution the cells fluid rushes out of the cell and causes it to shrivel. In a hypotonic solution water rushes into the cell and causes the cell to expand and eventually pop. In a isotonic solution water rushes in and out of the cell and causes the cell to stay the same. HYPOTHESIS: On the carrot lab the carrot that will be placed in the salt water will be hypertonic and will shrink because the cells will shrivel. The carrot that is placed in just water will be hypotonic and will

concentrations between a cell and its environment. The terms hypotonic‚ hypertonic‚ and isotonic are used in referring to the identification of the possible relative concentrations. The first term‚ hypotonic‚ is the solution that contains lower concentrations of solute particles‚ which means that the concentration inside the cell is greater than the concentration outside. A hypotonic solution causes the cell to swell in size. The second term‚ hypertonic‚ is the solution that contains higher concentration

concentration. Both refer to movement in/out of a cell‚ but osmosis refers specifically to water. 2. Isotonic‚ hypertonic‚ and hypotonic all refer to the comparison of concentrations of solutes in verses out of the cell. Isotonic is when the concentration in the cell is the same as the concentration outside of the cell. Hypertonic is when the concentration outside of the cell is greater than inside. And hypotonic is the opposite; the concentration outside of the cell is less than inside of the cell.

this is showing that our first 2 test tubes were hypotonic‚ which means water is sucked out. Thus in a less concentrated environment. Whereas test tube C was less isotonic‚ and the test tubes E and F were hypertonic‚ stating that it is situated in a more concentrated environment. Some of the potatoes gained mass because the water is going in the potato‚ showing that the potato is more concentrated than the environment. Thus the environment is hypotonic which equals to a higher concentration. In the

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle‚ and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass

physical environment. The cells may be isotonic‚ hypotonic‚ and hypertonic. Isotonic is when the cell and is environment have equal concentrations of solutes. Therefore cells in an isotonic solution do not experience osmosis. When the cell is hypotonic it has a lower concentration of solutes so water will move out of the cell. When the cell is hypertonic‚ it will have a higher concentration of solutes and water will move into the cell to attempt to reach an isotonic state. The primary purpose of this
Premium Osmosis Concentration Diffusion
little on osmosis. Osmosis takes place when two solutions of different concentrations are separated by a semi-permeable membrane in which the solvent can pass through but not the solute. In our experiment‚ we used a sucrose solution that will be a hypotonic concentration of solute. This tells us that the solution has a lower concentration of water than does the cells. Therefore‚ due to osmosis‚ the cells will gain water weight also proven in the experiment given. If osmosis isn’t taking place usually

Introduction When plant and animal cells are placed in a hypotonic environment‚ osmosis will occur. The structure of these cells determines the response to the difference in gradient‚ whether this be lysis (the explosion of cells due to the sudden increase in water pressure within the cell) in animal cells or turgor pressure (the pressure created by the increase in water pressure within the cell) in plant cells. Turgor pressure prevents further osmosis‚ which causes the water potential outside the

temperatures has a mass of very nearly one kilogram. Osmolarity and tonicity are related‚ but different concepts. Thus‚ the terms ending in -osmotic (isosmotic‚ hyperosmotic‚ hyposmotic) are not synonymous with the terms ending in -tonic (isotonic‚ hypertonic‚ hypotonic). The terms are related in that they both compare the solute concentrations of two solutions separated by a membrane. The terms are different because osmolarity takes into account the total concentration of penetrating solutes and non-penetrating
