Diffusion‚ Osmosis‚ Active Transport There are two ways in which substances can enter or leave a cell: 1) Passive a) Simple Diffusion b) Facilitated Diffusion c) Osmosis (water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms‚ ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout. Some major examples of diffusion

Microbiology Osmosis Lab Report Lab Experiment 9 Osmosis Introduction Kinetic energy is present in cells and its this energy that causes the cells to move. Diffusion causes cells to move from a higher concentration to a lower concentration. Osmosis is a diffusion that allows movement of water through a selectively permeable membrane. Osmosis occurs until it reaches equilibrium‚ or when the concentration on each side is the same. This is called an isotonic solution. A solution with differing

the calorimeter was filled with 100 mL of water using a graduated cylinder‚ and the temperature of the water was found and recorded. Next‚ the beaker was filled 3/4 full with water and placed on the stand of the ringstand above a gently burning flame from the Bunsen Burner. Then‚ the mass of the test tube and wax was found and recorded‚ and the tube was placed in the beaker. After the wax in the tube melted‚ the tube was placed in the calorimeter‚ using a wire gauze. Lastly‚ once the wax in the tube

Osmosis is the movement of water across a membrane. It always navigates to the area of the membrane with a higher solute concentration. We take a closer look at the effects of osmosis in this lab through the examination of red blood cells (sheep)‚ plant cells (elodea)‚ and active transport in yeast. Under the microscope‚ we can determine the effects on plant and animal cells exposed to hypotonic‚ hypertonic‚ and isotonic sodium chloride solutions. Plant cells have a cell wall; however‚ animal cells

How Do Different Factors Affect Osmosis Aim: To discover The Different factors that affect osmosis. Factors that affects the rate of osmosis in a potato: * Time * Temperature * Molar * Sucrose solution * NaCl solution * Concentration of liquid * Age of the potato * Variety of the potato * Potassium‚ K(AQ) Factor Chosen: Different Molar of Sucrose Solution In this investigation I will change the molar of sucrose solution to find the increase or decrease
