- Expansion Diffusion.
- Contagious Diffusion.

What are the types of diffusion?
Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion.
What are the 3 types of diffusion?
The three types of diffusion are – simple diffusion, osmosis and facilitated diffusion.
- (i) Simple diffusion is when ions or molecules diffuse from an area of high concentration to an area of low concentration.
- (ii) In osmosis, the particles moving are water molecules.
What are the types of diffusion in AP Human Geography?
Stimulus, contagious, and hierarchical diffusion are all kinds of expansion diffusion. Expansion diffusion is when innovations spread to new places while staying strong in their original locations.
What is spatial diffusion in geography?
Spatial diffusion is the process by which behavior or characteristics of the landscape change as a result of what happens elsewhere earlier. Spatial diffusion is the spread of the phenomenon, over space and timed, from limited origins. Diffusion processes are common in nature.
What are the three diffusion?
1 Answer. Simple diffusion, osmosis and facilitated diffusion.
What are the 3 characteristics of diffusion?
Factors that Affect Diffusion. Diffusion is affected by temperature, area of interaction, steepness of the concentration gradient and particle size.
What are 3 types of cultural diffusion?
There are five different types of cultural diffusion. They are expansion, contagious, hierarchical, stimulus, and relocation diffusion.
What is hierarchical diffusion example?
Hierarchical diffusion is when a cultural trend is spread from one segment of society to another in a pattern, such as hip hop spreading from cities to less populated areas. Stimulus diffusion is when a cultural trend spreads but is changed by those adopting the idea, such as American practitioners of yoga poses.
What are 3 examples of simple diffusion?
In the cell, examples of molecules that can use simple diffusion to travel in and out of the cell membrane are water, oxygen, carbon dioxide, ethanol and urea. They pass directly through the cell membrane without energy along the concentration gradient.
What are the 3 types of osmosis?
What are the three types of osmotic conditions that affect living cells? The three types of osmotic conditions include- hypertonic, isotonic, and hypotonic.
What is spatial diffusion example?
Recall that expansion diffusion is defined as that group of spreading phenomenon that has a source and diffuses outwards from the source. The spread of a fire, or pollution being emitted from a point source are examples of this type of spatial diffusion.
What is spatial diffusion?
Spatial diffusion is the process by which behavior or characteristics of the landscape change as a result of what happens elsewhere earlier. Spatial diffusion is the spread of the phenomenon, over space and timed, from limited origins. Diffusion processes are common in nature.
What is diffusion in geography?
In geography, the term diffusion refers to the spread of people, things, ideas, cultural practices, disease, technology, weather, and other factors from place to place.
What is facilitated diffusion simple?
In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
What is osmosis and diffusion?
Osmosis is the movement of solvent particles from a solution that is diluted to a more concentrated one. In contrast, diffusion is the movement of particles from a higher concentration region to a region of lower concentration.
What are the three types of expansion diffusion?
Stimulus, contagious, and hierarchical diffusion are all kinds of expansion diffusion. Expansion diffusion is when innovations spread to new places while staying strong in their original locations.
What is passive diffusion and facilitated diffusion?
Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins. Some molecules and ions such as glucose, sodium ions, and chloride ions are unable to pass through the phospholipid bilayer of cell membranes.
What is passive and active transport?
Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules. In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.
What is active and passive transport?
Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules. In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.
What is facilitated diffusion and active transport?
Facilitated diffusion does not require cellular energy to transport molecules. However, active transport uses ATP or electrochemical potential to transport molecules. Therefore, the main difference between facilitated diffusion and active transport is the use of energy for the transportation by each method.
What is passive diffusion and active diffusion?
The main difference between active and passive diffusion is that active diffusion pumps molecules against the concentration gradient by using ATP energy whereas passive diffusion allows the molecules to pass the membrane through a concentration gradient.
What is the difference between active transport and facilitated diffusion?
Facilitated diffusion is down the concentration gradient from higher concentration to lower concentration and does not require energy, whereas active transport is from lower concentration to higher concentration against the concentration gradient and requires energy.
What is the difference between simple diffusion and facilitated diffusion?
In simple diffusion, the substance passes between the phospholipids; in facilitated diffusion there are a specialized membrane channels. Charged or polar molecules that cannot fit between the phospholipids generally enter and leave cells through facilitated diffusion.
What is major difference between facilitated and passive diffusion?
The driving force for simple diffusion is the concentration gradient across the membrane. Simple diffusion is a passive transport as thus, doesn't require any energy. Facilitated diffusion is also a passive transport mechanism that doesn't require any energy, but some facilitated diffusion processes can be active.
What is passive diffusion mechanism?
Passive diffusion is the process by which molecules diffuse from a region of higher concentration to a region of lower concentration. It is the most important mechanism for passage of drugs through membranes. Lipid soluble drugs penetrate lipid membranes with ease.
What is the difference between facilitated diffusion and passive transport?
Passive modes of transportation include: Solutes move from a higher concentration region to a lower concentration region by simple diffusion. In facilitated diffusion, solutes move through a membrane from higher to lower concentrations with the aid of transmembrane proteins.
What is the difference between passive and facilitated diffusion?
The driving force for simple diffusion is the concentration gradient across the membrane. Simple diffusion is a passive transport as thus, doesn't require any energy. Facilitated diffusion is also a passive transport mechanism that doesn't require any energy, but some facilitated diffusion processes can be active.
