Why is the cell membrane said to be selectively permeable?
Understand the Problem
The question is asking for an explanation of the concept of selective permeability of the cell membrane, which involves understanding how the cell membrane controls what enters and leaves the cell and why this property is important for cell function.
Answer
The cell membrane is selectively permeable because it only allows specific molecules to pass through.
The cell membrane is said to be selectively permeable because it only allows specific molecules to enter or exit the cell, controlling the flow of substances. This feature is due to the structure of the phospholipid bilayer and the specific proteins that act as gateways.
Answer for screen readers
The cell membrane is said to be selectively permeable because it only allows specific molecules to enter or exit the cell, controlling the flow of substances. This feature is due to the structure of the phospholipid bilayer and the specific proteins that act as gateways.
More Information
The selective permeability is critical for maintaining the cell's internal environment and allows for communication and transport of necessary substances.
Tips
A common mistake is thinking the cell membrane allows all substances through; it actually selectively permits specific molecules.
