Question 8

The function of a cell is determined the amount of surface area it has.Is this statement true or false and why?

Accepted Answer

A) False.Fewer cells with equal mass will have greater surface area and therefore greater transport efficiency. 
B) True.A cell with the same mass can increase surface area with structures like microvilli that enhance absorption functions. 
C) False.Cells of equal mass cannot change their surface area;therefore cell mass determines cell function. 
D) True.Greater cell mass always increases cell surface area leading to greater efficiency of transport. 
A) False.Fewer cells with equal mass will have greater surface area and therefore greater transport efficiency. 
B) True.A cell with the same mass can increase surface area with structures like microvilli that enhance absorption functions. 
C) False.Cells of equal mass cannot change their surface area;therefore cell mass determines cell function. 
D) True.Greater cell mass always increases cell surface area leading to greater efficiency of transport.

E) primary cell walls 
A) middle lamella 
B) hemidesmosomes 
C) plasmodesmata
