So define the following solution is isotonic, hypertonic, hypotonic, and describe what would happen to an animal cell place in each of the solutions.
00:13
The first one.
00:16
Now, first of all, you place the cell that is a 0 .5 % solution of solute in a solution that also has 0 .5 % solution of solute.
00:26
Which direction is the water going to move and what happened to the cell? so you have a beaker, you have a solution, we have 0 .5%.
00:36
Now you have a cell inside of the solution is also 0 .5%.
00:43
So in this case, the solution is called the isotonic.
00:47
The isotonic means that the concentration of in and outside of the cell is equal.
00:55
So they have the same concentration.
00:57
And in this case, there's no net water flow.
01:07
Because the osmosis, which means the concentration of the water equals in and out of the cell.
01:16
And what happens to the cell? well, cell look normal.
01:26
So there's nothing really happened to this animal cell.
01:29
So animal cell has a optimal condition in isotonic solution.
01:36
Second case, you place a cell that has 0 .5 % solution of solute in a solution that has 1 .5 % solution.
01:44
Which direction and water going to flow, what happened to the cell.
01:47
So now the second case, again, you have a beaker.
01:51
The beaker has 1 .5 % solution inside.
01:58
Then you have a cell.
02:00
The cell has a lower concentration of 0 .25%.
02:05
So now in this case, you have a higher concentration in outside than inside.
02:11
So the solution is considered as hypertonic.
02:16
Solution, which means it has a higher concentration than the cell...
