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.
Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
Do chemicals pass in and out of a cell through openings of the nucleus?
No they pass through the cell membrane. The cell membrane is selectively permeable to ions and organic molecules
What are the roles of an egg shell and membrane and how do particles pass through?
They're both there for protection. Gasses pass through the shell because it has microscopic holes - too small to pass even water. Gasses pass through the membrane by diffusion (after they devolve).
Why the waste can pass through the membrane?
Waste can pass through a membrane due to its size and composition. Membranes have small pores or channels that allow smaller molecules or ions to pass through, while larger molecules or particles are blocked. Additionally, the chemical properties of the waste may also play a role in its ability to pass through a membrane.
What is the semipermeable membrane?
The cytoplasm of a cell is surrounded by a cell membrane or plasma membrane. The membrane is said to be 'semi-permeable', in that it can either let a substance pass through freely, pass through to a limited extent or not pass through at all.the membrane is somewhat effective at letting fluids through

What is the part of the cell that materials pass through?
The membrane

No they pass through the cell membrane. The cell membrane is selectively permeable to ions and organic molecules
A membrane that allows only certain substances to pass through is a?
A permeable membrane
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
Does the cell membrane let things pass through it?
Yes the cell membrane lets things past through it. The cell wall does not allow things to pass through.
Which nutrient can pass through a dialysis membrane?
Molecules that are small enough to fit through the membrane pores. Water molecules, sodium, potassium, and chloride can pass through dialysis membrane because they are small in size. Proteins have a bigger size than the pores of the dialysis membrane so they don't pass through it, they stay in the blood plasma.
What is meant by membrane is membrane?
a partially permeable membrane allows some molecules or ions to pass through it
What are the roles of an egg shell and membrane and how do particles pass through?
They're both there for protection. Gasses pass through the shell because it has microscopic holes - too small to pass even water. Gasses pass through the membrane by diffusion (after they devolve).
What single characteristic of the semipermeable membrane used in the laboratory determines the substances that can pass through them?
The size of the membrane pores determines which molecules can pass through.
