The surface area of a cell is a measure of the part of the cell that comes into contact with its surroundings. it is through the surface that a cell exchanges materials with the surroundings. for a particular amount of cell volume, the cell must have access to at least some minimum amount of surface in order to effectively excrete wastes and take in needed materials. the larger a cell gets, the smaller the cells' surface-area-to-volume ratio becomes. given this information, which of the following is true? a. the size of a cell is limited by its surface-area-to-volume ratio. b. cells must stay exactly the same size once they are formed. c. small cells are inefficient due to their lack of surface area. d. all of these

1. to get the materials it needs that move across its surface? assignment: cell size exploration cell length of one side area of one side of the cube (l × w) surface area (area of one side × 6 sides) volume (l × w × h) surface area / volume ratio of surface area to volume (for example, 5: 1) a 1 cm b 2 cm c 3 cm refer to your data table to answer these questions. 1. what happens to the ratio of surface area to volume as the cell size increases without the cell changing shape? what does a surface area/volume ratio of 6: 1 mean for the cell’s ability 2. what does a surface area/volume ratio of 3: 1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6: 1?
