Cell Transport: Hypertonic vs. Hypotonic vs. Isotonic

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell, leading to cell shrinkage.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell, leading to cell swelling.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water and the cell maintaining its size.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and shrinks due to the higher concentration of solutes outside the cell.

Front

What happens to a cell in a hypotonic solution?

Back

The cell gains water and may swell or burst due to the lower concentration of solutes outside the cell.

Front

What happens to a cell in an isotonic solution?

Back

The cell remains the same size as the concentration of solutes is equal inside and outside the cell.

Front

How does osmosis relate to cell transport?

Back

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of the cell membrane in transport?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the effect of a 30% salt solution on a 70% water cell?

Back

The cell will lose water and shrink because the salt solution is hypertonic compared to the cell's internal environment.

Define diffusion in the context of cell transport.

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration until equilibrium is reached.
