All the imports and exports of cell moves through plasma membrane by diffusion. Which includes proteins, water, nutrients and the products of the cell.
The material in excess amount in or out of the call moves in or out of the by diffusion.

How does diffusion differ from osmosis?
Diffusion is simply the migration of a substance through a medium.eg. If you put a drop of Iodine in a Becker of water it will slowly diffuse through the whole solution. This is an example of the second law of thermodynamics.Osmosis requires a semi-permeable barrier that creates or allows a disparity in concentration on either side.Osmosis and Diffusion:Remember that molecules tend to move from an area of higher concentration to an area of lower conventration. In osmosis, water molecules move by diffusion from an area where they are highly concentrated through tue cell membrane tp an area where they are highly concetranted through the cell membrane to an area where they are less concetrated.
How do substances like co2 and water move in and out of the cell?
By the process of diffusion and osmosis.
Explain how osmosis differs from diffusion?
Osmosis differs from Diffusion because in osmosis only water moves, and during diffusion, small molecules move across the cell membrane.
How do gas molecules move around a room?
Through the diffusion process.
Three ways that substances can move into and out of a cell?
One way is diffusion, another is osmosis and Active transport.
Diffusion allow materials allows material?
actually diffusion allows materials to move in and out of the cell
How does sodium ion molecule move into the cell through cell membrane?
Through diffusion.
What is the process in which molecules move in and out of cell?
The movement of things through the cell would be called diffusion. If it is water we are talking about then it is called osmosis. diffusion and osmosis are examples of inactive transport. Active transport involves specific proteins in the cell that pull material in the cell though the cell membrane.
What are the process in which materials move through a cell membrane?
diffusion and osmosis
How do proteins and polysaccharides that are too large to move onto a cell through diffusion or active transport move into the cell by?
Endocytosis.
How do the small molecules of oxygen and carbon dioxide move through the cell membrane?
They move via diffusion across a gradient.
What is is called when vesicles are used to move substances out of the cell?
The process that requires transport vesicles to transfer material out of a cell is called exocytosis.
When particles move out of a cell through diffusion the cell?
If the diffusion is moving particles from higher to lower concentration, it uses no energy from the cell; this is passive diffusion. However, if it is active diffusion, the cell is pumping out specific molecules into a higher concentration, therefore using energy.
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
What does active transport and facilitated diffusion have in common?
Active transport is when proteins move substances into the cell while expending energy. Facilitated diffusion is the movement of chemicals through a protein into a cell.
What substances would be moved across the cell membrane by diffusion?
Smaller particles are more likely to move by diffusion. Fat soluble substances are also more likely to move through diffusion also.
What are the functions of facilitated diffusion?
the point of facilitated diffusion is to help move sugars and amino acids through the cell membrane the ready set <3
