Multiple Choice
In eukaryotic organisms that possess a cell wall (e.g., plants and fungi), what is the primary function of the cell wall?
A
To synthesize proteins by translating mRNA into polypeptides
B
To provide structural support and protection, helping maintain cell shape and prevent osmotic lysis
C
To generate most of the cell's ATP through oxidative phosphorylation
D
To regulate which molecules enter and leave the cell via selective permeability
Verified step by step guidance1
Identify the main components and functions of the cell wall in eukaryotic organisms such as plants and fungi.
Recall that the cell wall is a rigid layer located outside the plasma membrane, composed mainly of polysaccharides like cellulose in plants and chitin in fungi.
Understand that the cell wall's rigidity provides mechanical strength, which helps maintain the cell's shape and protects it from physical damage.
Recognize that the cell wall also prevents osmotic lysis by resisting excessive water intake, thus maintaining cellular integrity in hypotonic environments.
Differentiate the cell wall's function from other cellular processes such as protein synthesis, ATP generation, and selective permeability, which are roles of other organelles or structures.
