germination is the uptake of water by the seed. This is the part where osmosis takes place. Osmosis is the diffusion of water across a selectively permeable membrane in which the water moves from a high concentration to an area where there are water molecules with a low concentration. Osmosis is similar to diffusion in the way mentioned earlier with the molecules moving from high to low concentration. Another similarity that osmosis shares with diffusion is that both processes work as passive transports

within a cell are called Diffusion. When molecules move across a cell membrane it is known as Osmosis. Diffusion is the process by which molecules of a substance move from areas of higher concentration of that substance to areas of lower concentration. Diffusion can be the transfer of anything anywhere. However‚ that is not true for osmosis. Osmosis is diffusion‚ but a specific type of diffusion. Osmosis is only the diffusion of water molecules through a selectively permeable membrane and a concentration

Title: Osmosis in quails’ egg Aim: To observe the effect of different concentrations of sodium chloride on a de-shelled quail’s egg To explain the effects in terms of osmosis Research Questions: Does the different concentrations of sodium chloride on a de-shelled quail’s egg effect the final mass of quail’s eggs that is measured by using electronic weighing balance? Introduction: “If a cell is to perform its functions‚ it must maintain a steady state in the midst of an ever-changing

because the lower the concentration of sugar the greater its water potential and consequently the faster the rate of osmosis. The results show that in each of the five sugar solutions‚ the rate of osmosis decreased with time. This happened because the difference in water potential between the inside and the outside of the beetroot time decreased as the experiment proceeded. Osmosis occurred most in distilled water because this contained the highest water potential when compared with the other beakers

9/17/2013‚ Lois Andersen & Claire Ma “The Power of Osmosis” The purpose of the lab was to discover‚ through osmosis‚ the concentration of sugar water in a potato. First‚ potatoes were cut into strips about 3 centimetres in length and six strips were individually massed. Next‚ the six strips were placed in 6 different Dixie cups‚ labelled A‚ B‚ Q‚ X‚ Y‚ and Z. Each of the Dixie cups were then filled just enough to cover the potato strips‚ with substances that matched the letters of the cups

concentration of the reactants and products does not change with time. Before this experiment‚ we were educated on how osmosis functions. Osmosis is a process which molecules and water take to usually get through a selectively permeable membrane in order to reach equilibrium. It is a passive transport which requires no ATF and water moves from high to low water concentration. When osmosis is completed‚ there should be an equal concentration o water on both sides of the experiment. We have also learned

Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

transport are endocytosis‚ exocytosis‚ and phagocytosis. Passive transport does not require energy it is powered by the concentration gradient of the molecule. Examples of passive transport are diffusion‚ facilitated diffusion‚ filtration‚ and osmosis. In our Osmosis Lab I used a Grade a large egg from the grocery store. Its circumference is 5 ½ inches it is smooth with no cracks. I carefully place the egg in a clear plastic cup and fill the cup with vinegar. I immediately notice bubbles covering the

Diffusion and Osmosis Diffusion -the process by which molecules spread from areas of high concentratiion‚ to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM DIFFUSION Concentration gradient - a difference between concentrations in a space. Molecules will always move down the concentration gradient‚ toward areas of lesser concentration. Think of food coloring that spreads out in a glass of water‚ or air freshener sprayed in a room

the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations 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
