For biology i have to design an experiment which shows the affect of surface area on beets pigmentation leakage and rate of osmosis can you help me think of what i can do to test it and also help me figure out how beets pigment leakage and rate of osmosis are affected by surface area. Transcript of how the concentration of salt solutions effect the rate of osmosis color is tinting 100ml below the surface and is slowly filling the top of the center with color but deeping in color glass more 1:00-there's a tendril in the center-left area of the glass reaching down to 125ml, on the surface the dye is not touching the. International baccalaureate biology tutorial 216 explain the importance of the surface area to volume ratio as a factor limiting cell size.

Cells need to excrete wastes and release heat at the same rate as it produces wastes and heat if the cell becomes too large, there will not be enough surface area to excrete all the wastes and release all the heat produced by the cell (the volume is too much. This is a lesson that i taught to my year 10 biologists to help them understand the relationship between surface area and rate of diffusion they we easily able to link the results to why cells are so small (when combined with surface area:volume ratio) and why the small intestine has villi. Abstract: two comprehensive reviews of a software program that illustrates experimental simulation covering concepts of diffusion, osmosis, random motion, and the properties of cell plasma membranes.
Osmosis investigationaim:the aim of this experiment is to investigate the effect of changing theconcentration of sucrose on the rate of osmosis in cylinders ofpotatoes it is the diffusion of water through a partially permeable membrane from a more dilute solution to a more concentrated solution – down the diffusion and osmosis problems. The two factors that are particular to diffusion through a membrane are surface area and permeability a membrane with smaller surface area or lower permeability will impede molecular movement and thus lead to slower diffusion. The rate of osmosis is faster with a higher concentration gradient how does temperature affect the rate diffusion across a cell membrane it increases kinetic energy, which causes molecules to move faster thus increasing the rate of diffusion. The ratio of surface area to volume strand life at the molecular and cellular level they conduct experiments based on the principles of osmosis in part 4, they investigate experiment to test the effect of cube (cell) size on the rate of diffusion 3 have students cut the gelatin into different size cubes—ie, 1-cm, 2-cm, and 3-cm.
Surface area to volume ratio and the relation to the rate of diffusion aim and background this is an experiment to examine how the surface area / volume ratio affects the rate of diffusion and how this relates to the size and shape of living organisms. Just as the surface area of an object affects the rate of osmosis, so too does the salinity of the solution that the object is inthe salinity of the solution will also determine whether water goes in or out of the object, or if there is no net osmosis as an example, consider a jellyfish. Surface area/ volume ratio controls the the diffusion rate through membranes/ semipermeable membranes in a spherical body, like a bacterial cell, when the ratio is more than 1 ( like in newly divided cell, more solutes diffuse in the cell from the aqueous outside environment in side the cell through its semipermeable membrane and that helps in the cell to grow and gets larger.
Investigate the factors affecting the rate of osmosis essay - investigate the factors affecting the rate of osmosis planning osmosis is the diffusion of water from a lower concentration of solute to a higher concentration of solute, through a partially permeable membrane. More the surface area to volume ratio, more is the diffusion surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time amoeba and some bacterias are flat and have large surface area to volume ratio so the diffusion rate is very high due to large surface area. The more solution there is the larger quantity the glucose has to equalize over o pressure – areas of different pressure have different water potentials o surface area – the larger the surface area, the more water can be absorbed into the cells, therefore altering the rate of osmosis.
Rates of reaction what is the effect of increasing the surface area of a solid on the rate of a chemical reaction a solid that is present in a solution can only react when particles collide with the surface of the solid if the area of the solid surface is made bigger then more particles can collide with it per second and the rate of the chemical reaction increases. How does the permeabilty of membrane affect the rate of diffusion membrane are permiable to some molecules and impermeable to others so some things can get across through simple diffusion and other things have to use transport proteins to get across the plasma membrane. The surface area over which the osmosis occurs can change the speed at affects the rate of osmosis, because the free water molecules need the reason weight was chosen to measure the change caused by osmosis is because the change in potato weight of the potato would be much.
Surface area to volume ratio and the relation to the rate of diffusion essay sample aim and background this is an experiment to examine how the surface area / volume ratio affects the rate of diffusion and how this relates to the size and shape of living organisms. Osmosis is the diffusion of water which takes place through a surface a larger surface area would mean faster diffusion the osmotic pressure after equilibrium was established would not change yes think of water molecules queuing up to cross the semi-permiable membrane down the concentration. An increased surface area to volume ratio increases the rate at which water diffuses through a plant as the surface area to volume ratio increases, the cell becomes thinner allowing for a shorter diffusion pathway hence, creating a more rapid and efficient diffusion of water across the cells.
