Diffusion continues until it reaches equilibrium. Osmosis is similar to Diffusion but it’s the process in which water moves across a semi-permeable membrane and goes to the higher concentration of solute.1 2.2. Important factors to Osmosis and Diffusion include Temperature‚ Concentration and Surface area to volume ratio. Temperature can affect the rate in which a solute dissolves in a solution‚ higher temperature faster rate of Osmosis. This is caused by the molecules movements being faster

different sucrose concentrations (0.15‚ 0.20‚ 0.25‚ 0.30‚ 0.35 and 0.50). It was expected that the potatoes would lose weight as the potatoes would have lower water potential when placed in a solution ‚ and in this can be taken from the theory of osmosis which states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn‚ 2009)‚ moving water from a high to a low concentration‚ so in this case water would move from the

How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and

The effects of osmosis on potatoes placed in different salt concentration Introduction: Osmosis is a movement of water across a semi-permeable membrane. This may only happen when there is a difference in concentration between the two sides of the membrane. The water moves from low concentrations to high concentrations. That is because the low concentrated area tries to dilute the opposite via osmosis. The effects osmosis has on a cell are either that it becomes turgid and hard as water enters

movement of molecules from an area of higher concentration to an area of lower concentration. Diffusion is driven by molecules kinetic energy until equilibrium is reached. The random movement of the molecules continues even at the equilibrium. Osmosis: Is the diffusion of water across a membrane. Hypertonic: Water diffuses out of the cell‚ causing it shrink. Hypotonic: Water diffuses into the cell‚ causing it to swell. Isotonic: Water diffuses into and out of the cell at equal rate‚ causing

Osmosis Egg Lab I. Introduction The reason for doing this lab was to see the process of osmosis. Osmosis is diffusion from a high concretion to a low concentration across a cell membrane. The cell membrane was represented by an egg without a shell. II. Hypothesis The egg that will placed in the distilled water will swell like a balloon. This is because distilled water is a hypotonic solution which makes water go in a cell (the egg without a shell) and make it swell. The egg that will placed

Introduction The movement of molecules from an area of greater concentration to an area of less concentration is called Diffusion. Osmosis is the diffusion of water through a selectively permeable membrane from an area with greater concentration of water to an area with less concentration. A Hypertonic Solution is a solution of a higher concentration of solutes and a smaller concentration of water molecules than another solution. However‚ an Isotonic Solution is a solution that contains an equal
