Teacher Answer Key Concept Covered: The Size of Cells 1. How does the size of a prokaryotic cell compare to the size of a eukaryotic cell? _______________________________________ ____________________________________________________ 2. What single factor limits the size of most cells? _____________ ____________________________________________________ 3. As a cell grows, its _______________ increases more rapidly than its _________________________. 4. Referring to question #3, why is this a problem for a growing cell? ________________________________________________ 1. Although there are exceptions, prokaryotes are generally smaller and less complex than eukaryotes. 2. The factor that limits the size of cells is the ratio between the volume and the surface area of the cell. 3. As a cell grows, its volume increases more rapidly than its surface area. 4. This is important because the nutrients, water, and oxygen that a cell needs must enter through its surface. Therefore, as a cell grows larger, the surface area becomes too small to allow these materials to enter the cell quickly enough to meet the needs of the cell. 5. ____________________________________________________ 5. Lets assume that the two cubes seen below represents cells of two different sizes. Lets further assume that materials can diffuse only 5 mm into the cells. Use a ruler to draw the area of the cell that can be supplied with materials from the outside of the cell. Do this for both cells. Which of the above cells will be more efficient at obtaining needed materials from the environment? Explain. __________ The smaller cell will be more efficient at moving in needed materials because it has a high surface area to volume ratio.
