What are you considering when you referring to how easily materials can pass through membrane?
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
What is a membrane that only allows certain materials to pass through?
A membrane that permits the passage of only certain molecules is called a semi-permeable membrane. In its simplest form, this separation process is based on molecular size. Smaller molecules pass through and larger ones are retained. In most biochemical processes, a concentration gradient drives the movement of molecules through the membrane.
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.
Why the line-with-gaps model is sufficient to explain the movement of materials in osmosis?
Because it is a differentially permeable membrane so water can fit through but no other large molecules can. it is a passive process. :)
Is water enters a cell through a cell wall by a process called osmosis true?
Yes. But only through a permeable or semi permeable membraneEDIT: The cell membrane is not itself permeable to water. However there does exist a type of protein pore called an aquaporin in the membrane that can allow water to pass through, driven by diffusion or osmosis.

What takes materials in and out of a cell?
The plasma member is a selectively permeable membrane which allows the entry and exit of substances in and out of the cell through the process of diffusion.

What substance can diffuse through a differentially permeable membrane?
Diffusion across a membrane in biology is referred to as 'osmosis' & osmosis is the process by which solvent molecules move from a region of high conc. to low concentration and this can therefore occur only in one direction at a time for a perticular solution. this is a really smart answer im surprised

How cell membrane are 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.
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.
Why the line-with-gaps model is sufficient to explain the movement of materials in osmosis?
Because it is a differentially permeable membrane so water can fit through but no other large molecules can. it is a passive process. :)
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
What phrase best describes osmosis A process by which A the cytoplasm divides B DNA synthesizes C molecules distribute balanced by movement D selectively permeable membrane allows exchange through it?
Osmosis is the process where a selectively permeable membrane allows the movement of water through it.
What type of molecules can easily go through your cell membrane or are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
