1. what happens to the ratio of surface area to volume as the cell size increases without the cell changing shape? 2. what does a surface area/volume ratio of 6: 1 (cm) mean for the cell’s ability to get the materials it needs that move across its surface? 3. what does a surface area/volume ratio of 3: 1 (cm) mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6: 1 (cm) ?

1. the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. 2. It depends on the unit of the ratio 6:1. If it is in cm1, then it means that it is similar to a cell of size 1 cm^3, which is normally too big to get materials from the surface. 3. a smaller cell has a better surface area to volume ratio, which means it is more efficient.

Yes he thought they should be left to chance why, because he thought that was the best thing to do
