Some substances but not others can cross the plasma membrane of a cell. This selective permeability is due to the membrane's lipid bilayer structure and embedded proteins, which regulate the movement of ions, nutrients, and waste. Small nonpolar molecules can typically diffuse freely, while larger or charged substances require specific transport proteins or channels to cross. This selective transport is crucial for maintaining the cell's internal environment and overall homeostasis.
What else can I help you with?
What property in the cell membrane that allows only some substances in?
Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.
The cell membrane forms a protective barrier between the external and internal environments. It is referred to as because it allows some substances to cross more easily than others and blocks other su?
The affirmation is correct.
What kind of protein helps some substances cross the cell membrane?
Carrier proteins help facilitate the movement of certain substances across the cell membrane by binding to specific molecules and carrying them across. These proteins undergo conformational changes to transport the substances across the membrane.
What Lets things in and out of the cell wall?
The cell membrane regulates the passage of substances in and out of the cell. It does so through various mechanisms such as diffusion, facilitated diffusion, and active transport. Additionally, some substances may require specific channels or transport proteins to cross the membrane.
How is the membrane permeability?
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
Is an ability of a plasma membrane to allow some substance to cross across the membrane more easily than others?
Yes, the ability of a plasma membrane to allow some substances to cross more easily than others is called selective permeability. This is due to the presence of specific transport proteins and channels that facilitate the movement of certain molecules while restricting others. The lipid bilayer of the membrane also plays a role in regulating which substances can pass through.
What does a selectively permeable membrane do?
A selectively permeable membrane allows some substances through it and does not allow others.Allows certain substances to pass but not others
What is a membrane called when only certain things can cross a membrane?
A membrane that only allows certain substances to cross is called a selectively permeable or semi-permeable membrane. It allows some molecules or ions to pass through while blocking others based on characteristics like size, charge, or solubility.
What characteristics of cell membrane allows for some substances to pass through but not others?

Why is a cell membrane called semi-permeable or selectively permeable?
As the cell membrane only allows certain substances to enter or leave the cell, meaning that while it IS permeable (as some substances can cross it), it is only selectively as not all substances are able to cross it, only some.
When some molecules go through a membrane faster than others the membrane is what?
The membrane is said to be selectively permeable or semipermeable when some molecules can pass through it faster than others. This property allows the membrane to regulate the passage of specific substances.
What is selectively permeable?
The property of a membrane or other material that allows some substances to pass through it more easily than others.Selective permeability refers to the control that a cell membrane has in terms of what it allows to cross it. This gives the cell membrane the ability to choose which molecules enter or leave.
What property in the cell membrane that allows only some substances in?
Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.

Carrier proteins help facilitate the movement of certain substances across the cell membrane by binding to specific molecules and carrying them across. These proteins undergo conformational changes to transport the substances across the membrane.
What is a membrane that allows some substances to pass through but excludes others?
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
A membrane that allows some substances to pass through while excluding others would be called?
selectively permeable
