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.


Is the cell membrane selectively permeable?

There are different types of plastics and most of them are nor permeable or selectively permeable .Cellophane is a specific plastic used in biological experiments as it is selectively permeable .


Are the membranes in a dialysis machine premeable or selectively permeable?

The membranes in a dialysis machine are selectively permeable, meaning they allow certain substances to pass through while blocking others. This selectivity allows toxins and waste products to be removed from the blood while retaining essential substances.


Is cytoplasm partally permeable?

Yes, the cytoplasm is partially permeable, meaning that some substances can pass through it while others cannot. This allows for control over which molecules can enter and exit the cell, helping to regulate cell function.


Does the cell membrane let the good cells in a the bad cells out?

It depends. Cell membranes are selectively permeable. Meaning it will only let certain things in and out of the cell.


Is the cell-membrane permeable?

Yes, the cell membrane is selectively permeable, meaning it allows certain substances to pass through while restricting others. This allows the cell to control the movement of molecules in and out of the cell to maintain internal balance and regulate cellular processes.


Are cell membranes permeable or semi-permeable?

Cell membranes are semi-permeable, meaning they allow certain substances to pass through while blocking others. This selectivity is facilitated by proteins embedded in the membrane that regulate the passage of specific molecules based on size, charge, and other properties.


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.


True or false The cell membrane is selectively permeable?

True. The cell membrane is selectively permeable, meaning it allows certain substances to pass through while blocking others based on size, charge, and other criteria. This property is essential for controlling the movement of molecules in and out of the cell to maintain cellular homeostasis.


What does the term selectively permable mean?

"Selectively permeable" refers to a membrane that allows certain substances to pass through while blocking others. This selectivity is based on the size, charge, or other properties of the molecules trying to cross the membrane. An example is a cell membrane, which permits the passage of specific molecules necessary for the cell's function while blocking others.


How can a door greeter relate to a cell membrane?

a cell membrane is semi-permeable. meaning that it selectively chooses between what can go in and out of the cell. A door greeter is similar to this because a door greeter can tell who to allow in/out of the building they are in.


The cell membrane controls what goes in and out of the cell true or false?

True. The cell membrane is selectively permeable, meaning it regulates the movement of substances in and out of the cell to maintain internal balance and protect against harmful substances.
