concentrations on the two sides. Tonicity is a measure of the osmotic pressure of two solutions separated by a semipermeable membrane. There are three types of tonicity that one solution can have relative to another. Those are hypertonic‚ hypotonic‚ and isotonic. Hypertonic solutions(more dissolved solute)-the solution with a higher concentration of a solute. Water leaves the cell and the cell shrinks. Hypotonoic solution(less dissolved solute)-the solution with the lower solute concentration

Part 1 Questions 1) What sort of environment (hypotonic‚ hypertonic‚ isotonic) did the extra fertilizer create around the roots of the corn? The extra fertilizer created hypertonic environment. 2) Keeping in mind your answer to the previous question‚ what do you believe caused the corn plants to wilt and eventually die? - I believe that the extra fertilizer having a higher concentration than the first round of fertilizer was not a good environment for the corn to try and survive in. 3)

Experiment 1. For each of the bags‚ identify whether the solution inside was hypertonic‚ hypotonic or isotonic in comparison to the beaker solution it was placed in. Bag #1’s solution was hypotonic compared to the solution of beaker #2. Bag #2’s solution was also hypotonic compared to the solution of beaker #2. Bag #3’s solution was isotonic compared to the solution of beaker #2 and Bag #4’s solution was hypertonic compared to the solution of beaker #1. 2. Which bag increased the most in volume

of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose water due to osmosis‚ results in an environment that is isotonic‚ hypertonic‚ or hypotonic. A hypotonic solution has a lower solute concentration than the cell so water moves into the cell causing the cell to swell. A hypertonic solution has a higher solute concentration than the cell so water moves out of the cell and into the solution causing the cell to shrink. In an isotonic solution‚ concentration

Introduction: During this laboratory exercise will identify by the graph given which is isotonic‚ hypotonic‚ or hypertonic. The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs. The process of urine formation and adjustment of blood composition involves three

concentration to an area of low solvent concentration. The water was diffused from a hypotonic solution to a hypertonic solution. Because of the amount of water in the vacuoles‚ the cell became turgid. The observation under the microscope of a cell of an onion skin soaked for 15 minutes in 1 molar sucrose solution showed that the cell membrane shrunk away from the cell wall in response of the hypertonic environment. The rigidity of the cell wall protects it from collapsing and therefore the onion cell

molecules to live. If blood cells‚ for example‚ are placed in contact with an isotonic solution‚ they will neither shrink nor swell. However‚ if the solution is hypertonic‚ the cells will lose water and shrink (plasmolyze). A real life example of such an event occurring is the consumption of saltwater. Saltwater from the ocean is hypertonic to the cells of the human body; the drinking of ocean water dehydrates body tissues instead of quenching ones thirst. If the solution is hypotonic‚ for example
