What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
How is osmosis different from simple diffusion?
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.
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.
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?
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.
Why aren't simple diffusion osmosis and filtration sufficient to supply the needs of the cell?
nothing
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 are 2 ways that substances across the cell membrane without using energy?
simple diffusion, facilitated diffusion, and osmosis (water)
