When does diffusion takes place?
from an area of lower concentration to an area of higher concentration.:melissa*
What happens in gaseous exchange?
The diffusion of gases takes place from their higher concentration to lower concentration. Exchange of oxygen by carbondioxide is the usual feature of breathing by lungs.
Which terms refers to the movement of molecules from an area of higher concentration an area of lower concentration?
Diffusion, a form of passive transport, is the movement of molecules from an area of greater concentration to an area of lower concentration. Osmosis is a special case involvement the movement of water from an area of higher concentration of water molecules to an area of lower concentration of water molecules. It takes place in all three states of matter-Solids, liquids and gases.
What happens to a cells when they are put in a higher concentration of water?
When a cell is placed in higher concentration of water then endosmosis of water in the cell takes place because in the cell water concentration is low and osmotic(solute) pressure is high so water moves from its higher concentration towards its lower concentration which means it moves inside the cell and the cell becomes turgid.
What takes place during osmosis?
Osmosis is the movement of water form its higher concentration to lower concentration through a semi permeable membrane. In it water can move from inside to outside or outside to inside.

What type of work uses ATP to pump substances across membrane?
Various pumps use ATP to move substances across membranes. The pumps are often moving substance from a lower concentration to a higher. This movement is called "against the gradient" as movement usually moves from a higher concentration to a lower to even out the concentration. It takes energy to keep this. The pumps are mostly proteins.
Where does the exchange of oxygen take place?
Oxygen exchange takes place in the alveoli or "sacs" located in the lungs. It occurs through diffusion, which just simply means moving a particle from an area of higher concentration to an area of lower concentration.
What are the characteristics of simple diffusion?
Diffusion is the process of molecules moving from high concentration to low concentration in a material. This will occur eventually through random movement and in simple diffusion is specifically without the aid of an intermediary such as integral membrane protein.
What is the difference between diffusuion and omosis?
Diffusion is the spreading out of a substance from a region where it is in higher concentration to one where it is in lower concentration. Osmosis is the special case of diffusion where the process takes place through a semi-permeable membrane, i.e. one which allows only some substances through it.
Is it true that water tends diffuse from a region where it is lees concentrated to a region where it is highly concentrated?
It is not true. All substances tend to diffuse from an area of higher concentration to that of lower concentration. This is called passive transport(no energy required), or in the case of water, Osmosis. However, if given energy, they can also move from an area of lower concentration to that of higher concentration. This process is called active transport.
Describe the difference between diffusion and osmosis?
although both are the movement of particles from an area of high concentration to low, diffusion is the movement of many kinds of substances however osmosis refers to the diffusion of water particles only from an area of high water concentration to an area of low water concentration.
