Over the course of evolutionary time animal body sizes have

Over the course of evolutionary time, animal body sizes have gotten larger, yet cell sizes have not. Cells have stayed proportionally the same size to remain efficient, because

A) if cells got larger, the demand for energy and raw materials would greatly decrease.

B) larger cells would become limited by the ability to move materials across the plasma membrane.

C) of limitations of the composition of the plasma membrane.

D) of the inability of the nucleus to produce sufficient DNA for larger cells.

E) the Golgi apparatus would not be able to meet the demands of cell transport of larger cells.

Solution

Answer.).option B. larger cells would become limited by the ability to move materials across the plasma membrane.

In the course of evolution cells develop into tissues then tissues to organs,organs to organsysytems and then the complete organism formation occurs.This was possible with the cells which are the building blocks of an organism. They remain in thier size in the entire course of evolution..
