Small and non-polar molecules can readily pass through the cell membrane. They follow the concentration gradient, moving from the higher concentration area to the region of lower concentration.

What substance will diffuse through a membrane?
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.
What substances diffuse into and what diffusen out of cells?
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
What occurs when water molecules diffuse through a membrane?
osmosis
Occurs when water molecules diffuse through a membrane?
Osmosis
Is the Visking tubing a partailly permeable membrane and why?
Yes, it is a partially permeable membrane. It allows certain substances like glucose and water molecules to diffuse through but not large molecules like starch and sucrose. Selectively permeable.
Which substances did not diffuse the membrane?
starch doesnt diffuse through the dialysis membrane.
What substance will diffuse through a membrane?
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.
What type of epithelial tissue allows substances to readily diffuse through it?
simple squamous
What type of substances pass through the membrane by facilitated diffusion?
soluble materials which can diffuse passively .
Why is it important that a cell membrane does not allow all dissolved substances to diffuse freely through it?
magnets
What is the process of taking material into a cell?
There are a huge number of ways that this can occur. Water can simply diffuse through the cell membrane through osmosis, while other substances diffuse through special channels in the cell membrane. Some substances have to be brought into the cell through active transport, which requires the use of ATP.
What lets substances like food and oxygen diffuse into body cells?
The semi-permeable membrane in cells. Allows some substances to go through and not others.
What substances diffuse into and what diffusen out of cells?
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
How does osmosis and diffusion differ?
Osmosis is a type of diffusion but through a barrier (membrane) while "diffusion" is not specified if there is a physical barrier or not. Gases diffuse through each other readily.
What characteristics is more likely to make a substance diffuse through the cell membrane?
Size. Actually very few substances are able to diffuse across the menbrane, most must be transported ie facilitated diffusion, active transport, or receptor-mediated endocytosis. Carbon dioxide, oxygen, water, and some lipid substances are able to diffuse across the membrane
Why do sugar molecules not diffuse through a plant cell membrane?
The membrane is semi-permeable. Sugar molecules are too large to diffuse through.
Which substance did not diffused through the membrane?
starch doesnt diffuse through the dialysis membrane.
