Write the title of the lab. What do you predict will be the relationship between a cell's size, its surface area:volume ratio, and the time it takes for the acid to diffuse to the center of the block? If a cell's size increases, then surface area:volume ratio will _____ and the time of diffusion into the cell will _____ because. cells, such as red blood cells, are about 10,000 nanometers across. Transitional epithelial cells from the renal pelvis, ureter, or bladder have more regular cell borders, larger nuclei, and smaller overall size than squamous epithelium. Data obtained by measuring the cell's volume and calculating its surface area is used to form conclusions about the size limitations imposed by diffusion. If a cell gets too large, it's SA:V gets smaller and there is not enough surface area to expel wastes or intake nutrients (the cell has bigger volume so needs more of them) fast enough and the cell shrinks or dies. The structure of cells leads specifically to it's function. 4) How does cell growth affect the cell’s surface-to-volume ratio? As cell growth increases the surface-to-volume ratio decreases.
