Question
Chapter 3, Problem 4SQ
Summary Introduction
Size of a cell increases gradually until they reach a certain point beyond which they do not grow. This fence to the cell growth happens due to a limitation imposed by the plasma membrane surface area. As the cells increase in size, its relative surface area is decreased.
