Name____________________________ Period_____________ Lab #_______ Mini-Lab Could a cell grow large enough to engulf your school? What would happen if the size of an elephant were doubled? At the organism level, an elephant cannot grow significantly larger, because its legs would not support the increase in mass. Do the same principles and limitations apply at the cellular level? Do the math! Procedure: 1. Prepare a data table for surface area and volume data calculated for five hypothetical cells. Assume the cell is a cube. (Dimensions given are for one face of the cube.) Cell 1: 0.00002 m (the average size of most eukaryotic cells) Cell 2: 0.001 m (the diameter of a squid’s nerve cell) Cell 3: 1.5 cm (the length of a human’s nerve cell) Cell 4: 15 cm (the size of an ostrich egg) Cell 5: 12 m (the length of a giant squid’s nerve cell) 2. Calculate the surface area for each cell using the formula: length x width x number of sides. 3.
