Multiple Choice
In the context of cell structure and function, what is the primary purpose of the cell wall?
A
To generate most of the cell’s ATP through oxidative phosphorylation
B
To regulate the selective transport of molecules into and out of the cell
C
To provide structural support and protection, helping maintain cell shape and prevent osmotic lysis
D
To store genetic information and control gene expression
Verified step by step guidance1
Identify the main components of a cell and their functions, focusing on the cell wall, cell membrane, mitochondria, and nucleus.
Recall that the cell wall is a rigid layer found outside the cell membrane in plants, fungi, bacteria, and some protists, but not in animal cells.
Understand that the cell wall's primary role is to provide structural support and protection, which helps maintain the cell's shape and prevents it from bursting due to osmotic pressure (osmotic lysis).
Compare this function with other options: ATP generation occurs in mitochondria, selective transport is managed by the cell membrane, and genetic information storage and gene expression control happen in the nucleus.
Conclude that the correct purpose of the cell wall is to provide structural support and protection, maintaining cell shape and preventing osmotic lysis.
