Turgor pressure is created by the pressure of the water inside the cell, created by water flowing in from the comparatively hypotonic solution environment. When this occurs, the water begins to build up a pressure inside the cell as the water flowing in causes the cell walls to be pressed out. Conversely, osmosis in plant cells can also cause plasmolysis. Plasmolysis is caused when a plant cell is placed in a comparatively hypertonic environment, causing water to flow out of the cell and into the environment. Because plant cells have cell walls though, the cell does not completely collapse as the cell walls keep the cell’s structure, while only pulling a little away from the cell membrane (because there is no incoming water causing pressure to push the walls out). When plasmolysis occurs, all the organelles in the plant cell begin to become concentrated in the center of the cell, as the cell wall moves, in further from the cell

The relationship between rate of diffusion/ osmosis, volume, and surface area can be easily seen and analyzed through the data that was collected from procedure one: Surface Area and Cell Size. Phenolphthalein is a dye-material in this lab that was used to determine whether a substance was an acid or base. This could be told as the phenolphthalein changed into a murky. Muddled and clouded color when mixed with acids. When the chemical aid was mixed in with a base, the color evolved into a vivacious purple, almost Barney purple. The use of this dye in the lab was to act as a visual aid to measure the rate of diffusion in different sized blocks of gelatin, consisting of agar. The first and smallest gelatin block had a surface area of 1.92 cm squared and a volume of 0.18 cm cubed. Our midsized/ medium gelatin specimen had a surface area of 12.612 cm squared and a volume of 2.96 cm cubed. The largest gelatin cube possessed the volume of 5.3 cm cubed and a surface area of 18.4 cm squared. It took 8:04 minutes for the hydrochloric acid to diffuse completely through the smallest gelatin block. This was regulated and measure visually, as the pink color from the gelatin block had began to diffuse out, due to the acid. The midsized gelatin block had a diffusion time of 40 minutes. It took approximately and hour for the largest gelatin block to diffuse completely. The smallest gelatin block’s surface area to volume ratio was 10.67 cm. The medium block had the ratio of 4.3 cm, and the lowest ratio belonged to the largest gelatin block, whose time was 3.5 cm. This data goes to prove the fact that the higher the surface area to volume ratio, the faster the diffusion rate. This lab’s data and facts revealed from it explain the phenomenon as to why most cells generally have a relatively high surface area to volume ratio. The reasoning behind this is that cells need a specific amount of diffusion to take place for cells to gain and loose specific material. This is in order to
