turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable to starch. 4B- The hypothesis was supported because the diffusion rate was faster shown from the agar blocks. The materials passed through the membrane easily and quickly in the small cells than the large‚ making them more efficient. The smaller the cell is‚ the faster it can transport signals. The bigger cell

1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer

influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that can affect the rate of this diffusion. Our intent was to measure

Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change

Lab Report #1 Facilitated diffusion By: Kelsey Clark Biology 2401 C1L Dr. Fanini October 2‚ 2017 Facilitated Diffusion Facilitated Diffusion is a type of passive transport that allows for lipid insoluble molecules or molecules that are too large to pass through a membrane. The molecules are able to pass through by binding with protein carrier molecules and moving down the concentration gradient. The rate of diffusion will continue to increase until the carrier proteins are saturated

Activity 1: Simple diffusion Introduction: Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient‚ simple diffusion does not require energy therefore it is ’passive’‚ substances are diffused across the membrane between the phospholipids.
