Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane

Diffusion in Cells Isabel Zak Question: How does the size of a cell affect the distribution of chemicals throughout the cell? Hypothesis: The larger the cell is‚ the more difficult it will be for the chemicals to reach the centre of the cell‚ and diffuse throughout it. This is because there will be a higher surface-area to volume ratio in the larger cells‚ making the centre of the cells further away from the surface. Therefore‚ when dipped in sodium hydroxide‚ the larger cells will not

1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1

The philosophy of continuous improvement is captured in the plan-do-check-act (PDCA) cycle proposed by W. Edwards Deming (Fitzsimmons et. Al.‚ 2013).

he mass and length of the potato piece must be kept the same in each experiment primarily because they affect the surface area of the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length

Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements of
