u003CResult
- The larger the piece, the less substance was absorbed in the center
- The larger the cells, the less efficient the exchange of substances is
- As the agar piece grows larger: the rate of increase in volume is greater than the rate of increase in surface area, reducing the efficiency of mass exchange
