00:02
So in here, you can see that you are given four different sets of data.
00:08
So in the first step, in has 5 % of salt, and out has 10%.
00:20
So in this case, that this cell has a lower concentration of salt than outside solution.
00:32
So this solution is considered as hypertonic, because it has a higher concentration of salt.
00:41
So in this case, water has higher osmosis inside.
00:46
Water is going to run out.
00:50
So solute, if the membrane is permeable, then it's going to move in.
01:00
So let's say diffusion, the solute moves in because you have more.
01:10
Solid outside the inside.
01:12
So it goes from higher concentration to a low concentration.
01:17
High concentration of solute.
01:24
So in this case, a diffusion occurs when you have higher concentration and lower concentration side.
01:31
The solute move from high side to low side.
01:38
Osmosis is the opposite.
01:42
It represents the water concentration.
01:46
Since you have higher concentration of salt outside inside.
01:50
Water has higher concentration inside.
01:52
So it means water, osmosis, is higher inside.
01:56
So the water moves out of the cell.
02:09
So now let's look at the second set.
02:13
Now, in 8%, out, 8%.
02:22
So in this case, in and out has the same concentration.
02:26
This is called isotonic.
02:29
Isotonic means the concentration of salt and water, they're equal.
02:33
Iso means equal.
02:34
In this case, no net diffusion or osmosis, because the two sides, they have the same concentration, no movement of solute or water.
02:50
So osmosis is the movement of water, diffusion is the movement of the solute.
02:55
Because the two sides equals, there's no net diffusion or osmosis.
03:00
It's a balanced condition.
03:04
The third case, you have inside 3 % glucose...
