Transport in Cells: Diffusion and Osmosis | Cells | Biology | FuseSchool
In this video we are going to discover how cells take in useful substances and remove waste using three methods of transportation: diffusion, osmosis and then in the second part we will look at active transport.
The exchange of materials occurs between cells and their environment, across the cell membrane. To make this exchange as efficient as possible, some organisms have evolved specialised exchange surfaces like the alveoli in the lungs, or root hairs in plants or the nephrons in kidneys.
Depending upon what is being exchanged and which direction along the concentration gradient things are travelling will determine whether diffusion, osmosis or active transport will be used.
Diffusion is the process in which...

Diffusion Animation!
One of the most important processes in biology is diffusion, the movement of particles from high concentration to low concentration. This process is passive, meaning that NO energy is used by the cell to make it happen.
So, how does diffusion work?
We will focus on simple diffusion across the phospholipid bilayer of a membrane, shown here. Notice that we have a high concentration of oxygen on one side of the membrane and a low concentration on the other side. I’m going to give you a second to think about this question: Which direction will the oxygen move? Make a hypothesis.
If you said that it will move down, toward the low concentration area, you are correct. Overall, molecules move from areas of high concentration to areas of low concentration. Another way to say this is tha...

Diffusion - Why can we smell hot food from a distance? | #aumsum #kids #science #education #children
Topic: Diffusion
Why can we smell hot food from a distance?
Hey. Looks like you have lost your way.
No. I know the way.
Fine. Don't listen.
See, I told you. Now listen to me.
There is a restaurant next to your house where hot sizzling food is available, right?
Yeah. Yummy.
Follow its smell and you will reach home.
I have reached home.
Do you know how the smell of that food reached you?
When food gets cooked, it releases some aromatic gases into the air.
The molecules of these gases spread and mix with air molecules.
When this air reaches our nose, we get the smell of food.
This process of spreading and mixing of a substance with another substance is called diffusion.
But then, why couldn't I smell the food inside my house from a distance?
This is because that food had become cold.

Transport in Cells: Diffusion and Osmosis | Cells | Biology | FuseSchool
In this video we are going to discover how cells take in useful substances and remove waste using three methods of transportation: diffusion, osmosis and then in the second part we will look at active transport.
The exchange of materials occurs between cells and their environment, across the cell membrane. To make this exchange as efficient as possible, some organisms have evolved specialised exchange surfaces like the alveoli in the lungs, or root hairs in plants or the nephrons in kidneys.
Depending upon what is being exchanged and which direction along the concentration gradient things are travelling will determine whether diffusion, osmosis or active transport will be used.
Diffusion is the process in which particles spread out from each other. They move from high concentration to an area of low concentration,down the concentration gradient until they are evenly distributed.
Osmosis is very similar to diffusion but just for water. It is the movement of water into or out of a cell. Again, it is the movement from a dilute solution (so high concentration of water molecules) down the concentration gradient to a more concentrated solution - so low concentration of water molecules. The water molecules move across a partially permeable membrane.

One of the most important processes in biology is diffusion, the movement of particles from high concentration to low concentration. This process is passive, meaning that NO energy is used by the cell to make it happen.
So, how does diffusion work?
We will focus on simple diffusion across the phospholipid bilayer of a membrane, shown here. Notice that we have a high concentration of oxygen on one side of the membrane and a low concentration on the other side. I’m going to give you a second to think about this question: Which direction will the oxygen move? Make a hypothesis.
If you said that it will move down, toward the low concentration area, you are correct. Overall, molecules move from areas of high concentration to areas of low concentration. Another way to say this is that they move DOWN THEIR CONCENTRATION GRADIENT.
But why do they do this? The answer is a bit more complex. Although we sometimes like to use analogies and say that molecules “want” to move from high to low, or that they “like” to have personal space and spread out to avoid being close to others, in reality molecules don’t really “like” or “want” anything.
Instead, diffusion happens because molecules are in constant random motion. Here is a model that shows this. Check it out.
Notice that the molecules move around randomly in every direction, but that overall they move from high to low concentration as they bounce around until there are roughly equal concentrations on both sides of the membrane. So, the net movement is from high to low concentration until equilibrium is reached. Equilibrium is when the concentrations on both sides are equal. But notice that movement continues even after equilibrium is reached. For this reason, we sometimes call this dynamic equilibrium. Molecules are still moving but there isn’t a net movement in any particular direction.
Now, let’s take a look at a model of a really important real-life use of diffusion, keeping you alive by getting oxygen into your blood. Take a deep breath and we’re going to look at what’s happening in your lungs as a result.
When you breathe in, oxygen rushes into your lungs producing a high concentration of oxygen in your lung tissues. This oxygen can then diffuse into your blood where it is picked up by red blood cells which carry the oxygen away. This ensures that the oxygen you breathed in can continue to diffuse down its concentration gradient (from high to low) into the bloodstream, keeping you alive.

Although we sometimes like to use analogies and say that molecules “want” to move from high to low, or that they “like” to have personal space and spread out to avoid being close to others, in reality molecules don’t really “like” or “want” anything.
Instead, diffusion happens because molecules are in constant random motion. Here is a model that shows this. Check it out.
Notice that the molecules move around randomly in every direction, but that overall they move from high to low concentration as they bounce around until there are roughly equal concentrations on both sides of the membrane. So, the net movement is from high to low concentration until equilibrium is reached. Equilibrium is when the concentrations on both sides are equal. But notice that movement continues even after equilibrium is reached. For this reason, we sometimes call this dynamic equilibrium. Molecules are still moving but there isn’t a net movement in any particular direction.
Now, let’s take a look at a model of a really important real-life use of diffusion, keeping you alive by getting oxygen into your blood. Take a deep breath and we’re going to look at what’s happening in your lungs as a result.
When you breathe in, oxygen rushes into your lungs producing a high concentration of oxygen in your lung tissues. This oxygen can then diffuse into your blood where it is picked up by red blood cells which carry the oxygen away. This ensures that the oxygen you breathed in can continue to diffuse down its concentration gradient (from high to low) into the bloodstream, keeping you alive.

Topic: Diffusion
Why can we smell hot food from a distance?
Hey. Looks like you have lost your way.
No. I know the way.
Fine. Don't listen.
See, I told you. Now listen to me.
There is a restaurant next to your house where hot sizzling food is available, right?
Yeah. Yummy.
Follow its smell and you will reach home.
I have reached home.
Do you know how the smell of that food reached you?
When food gets cooked, it releases some aromatic gases into the air.
The molecules of these gases spread and mix with air molecules.
When this air reaches our nose, we get the smell of food.
This process of spreading and mixing of a substance with another substance is called diffusion.
But then, why couldn't I smell the food inside my house from a distance?
This is because that food had become cold.
On heating food, the molecules of its aromatic gases gain kinetic energy and start vibrating faster.
They spread and mix easily into air, leading to an increased rate of diffusion.
As the food gets cold, the temperature of the aromatic gases decreases.
The kinetic energy of molecules decreases and they do not vibrate as much anymore.
Thus, the rate of diffusion decreases and we cannot smell the food from a distance.

#masstransfer #unitoperation #chemicalengineering #moleculardiffusion
The thermal motion of all (liquid or gas) particles at temperatures above absolute zero is known as molecular diffusion, which is frequently just referred to as "diffusion." The temperature, fluid viscosity, and particle size (mass) all influence how quickly this movement occurs. The net flow of molecules from a higher concentration area to a lower concentration area is explained by diffusion. When the concentrations are the same, the molecules still move, but since there is no concentration gradient, the molecular diffusion process has ended and is now controlled by the self-diffusion process, which results from the random motion of the molecules.

#masstransfer #unitoperation #chemicalengineering #moleculardiffusion
The thermal motion of all (liquid or gas) particles at temperatures above absolute zero is known as molecular diffusion, which is frequently just referred to as "diffusion." The temperature, fluid viscosity, and particle size (mass) all influence how quickly this movement occurs. The net flow of molecules from a higher concentration area to a lower concentration area is explained by diffusion. When the concentrations are the same, the molecules still move, but since there is no concentration gradient, the molecular diffusion process has ended and is now controlled by the self-diffusion process, which results from the random motion of the molecules.
Diffusion causes material to gradually mix, resulting in a homogeneous distribution of molecules. The outcome of molecular diffusion is referred to as a "dynamic equilibrium" since the molecules are still in motion yet an equilibrium has been reached. At some point, total mixing will occur at a constant temperature without the presence of any net external forces on the particles.
