Key Concepts

Turgor Pressure

Turgor pressure is the pressure exerted by the cell contents against the cell wall in plant cells. In a hypertonic solution, the loss of water reduces turgor pressure, leading to a loss of rigidity and structure in the cell.

Hypertonic Solution

A hypertonic solution has a higher concentration of solutes compared to the interior of a cell. When a cell is placed in such a solution, the water inside the cell moves out to balance the solute concentrations, leading to cellular dehydration.

Osmosis

Osmosis is the passive movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This process is central to understanding how cells interact with different solutions.

Plasmolysis

Plasmolysis is the process that occurs in plant cells when they lose water in a hypertonic solution. As water leaves the cell, the plasma membrane detaches from the rigid cell wall, which can disrupt normal cellular functions.

Transcript

00:01 So in this question, we're being asked, what would happen to a plant cell if it was placed in hypertonic solution? so let's tell what is meant by hypertonic solution.

00:13 So suppose that you have a cell and there's its nucleus and it has some solutes dissolved in the cytosol ions or other small molecules.

00:27 Now, a solution that is hypotonic to the cell means that it has a much.

00:31 Higher solute concentration than the cell.

00:36 There's a lot more, let's say, salt out here.

00:40 Okay? and water likes to travel from areas of low solute concentration to areas of high solid concentration.

00:50 So a cell placed in a hypertonic solution would lose water.

00:57 Water would move out of the cell.

00:59 Now, what is the structure of a plant cell? so real simply, and i'm going to draw it as a box here because it's simple.

01:05 But a plant cell has a cell wall, right? and let me draw the nucleus in the middle here.

01:17 And a plant cell also has a plasma membrane right inside of that cell wall.

01:24 Okay.

01:25 Now, you place this cell in a solution that has a high concentration of solutes.

01:35 Outside of it, okay? the water is going to leave the plant cell.

01:46 Okay, let me redo that.

01:47 I don't know why my pen did that...
