means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
What else can I help you with?
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
How does oxygen cross a selectively permeable membrane?
diffusion
What membrane that allows only some materials to move in and out of the cell is?
Such a membrane is said to be selectively permeable or semi-permeable.
If a substance is able to diffuse across a membrane then the membrane is said to be what?
selectively permeable
Why would cell membrane be destroyed if if it were permeable instead of selectively permeable?
Unwanted substances could get in, potentially destroying the cell and membrane.
A membrane that allows some substances to pass through while excluding others would be called a?
semipermeable or selectively permeable.
How is dialysis membrane selectively permeable?
a dialysis membrane is selectively permeable, it is used in experiments to simulate cellular membranes, and it is permeable to water but not to sucrose.
What is the basic strcture of a cell membrane?
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
Does the membrane of a cell is selectively permeable?
no
What is the relationship between cell membrane and selectively permeable?
Cell membranes are indeed selectively permeable.
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 definition of selectively permeable?
The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through).
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
Are cell membranes selectively permeable?
The membrane is selectively permeable because it has specific instructions on what the membrane can allow through based on the How_is_the_cell_membrane_semi_or_selectively_permeable, size, and ionization of the particle.
How cell membranes selectively permeable?
The membrane is selectively permeable because it has specific instructions on what the membrane can allow through based on the How_is_the_cell_membrane_semi_or_selectively_permeable, size, and ionization of the particle.
Do all cells have a membrane?
Cells have impermeable, permeable and selectively permeable membranes.
What is selectively permeable membrane made from?
Membranes that are permeable (loose) tend to have lots of what?
