Examples of organelle size control. (A) Cell specialization-The ER expands greatly from an undifferentiated cell (left) to a professional secretory cell (right). (Image from (43)) (B) Cell specialization-The outer segment in cone (COS label) and rod (ROS label) cells differ in shape and size. (C) Functional demand-Mitochondria ramify in a yeast cell grown in respiratory (right) vs. fermentative (left) media. (D) Organelle/cell size scaling-The nucleus in the larger cell (right) is larger than in the smaller cell (left).
