Osmosis is very similar to normal diffusion, but osmosis is only the movement of water through a "partially permeable membrane" where as simple diffusion is the movement of anything from an area of high concetrations to low, such as gas in a room.

The cell does not need to expand energy ATP in order to perform what?
simple diffusion and osmosis
The movement of particles from a high concentration to a low concentration?
diffusion
What is the diffusion of water through the cell membrane is called?
Facilitated Diffusion
Give 2 examples of passive transport?
Passive transport is when molecules pass freely through the membrane moving from the higher concentration area to the region of lower concentration. Three examples of this are diffusion, osmosis, and active transport.
What facilitates the diffusion of water across the cell membrane?
Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable. Simple diffusion and facilitated diffusionare similar in that both involve.
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
Three types of passive transport?
There are three forms of passive transport, or the movement of biochemical and other atomic or molecular substances across the cell membranes. They are: osmosis, simple diffusion or facilitated diffusion, and filtration.
What is the diffusion of water across a semipermeable memberane?
Diffusion of water across a semipermeable membrane is a type of simple diffusion given the special name of osmosis.
Compare and contrast simple diffusion and osmosis?
osmosis moves through a membrane diffusion moves from higher concentration to lower concentration
What are the examples of simple diffusion?
Osmosis is one of the easiest-to-understand examples of diffusion. Past that, you will need to define 'simple'.
How is osmosis similar to simple diffusion?
Both affected by Concentrations?
How are osmosis and diffusion different?
Diffusion is the net movement of a substance through a membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
What is one specific form of simple diffusion?
There's facilitated diffusion, where proteins channel in molcules; then there's active transport where the cell uses energy to bring in molecules that are to large or a different chemical configuration.
What are 3 different passive transports?
Diffusion, osmosis, Facilitated Diffusion
How is osmosis different than diffusion?
Osmosis is the same thing as diffusion, but occuring only with liquids in a selectively permeable membrane. An example of this is that water entering your cells is osmosis, but oxygen entering is diffusion.
What is the diffusion of water across the semipermeable?
Diffusion of water across a semipermeable membrane is a type of simple diffusion given the special name of osmosis.
Why aren't osmosis and simple diffusion sufficient for the transport of all substances?
Osmosis and simple diffusion are not sufficient for the transport of all substances due to their nature. They only have the ability to transport substances which can pass through the cell membrane.
