Cell Transport Review

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solute molecules is equal on both sides of the membrane, resulting in no net movement of water.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water leaves the cell, causing it to shrink, a process known as plasmolysis.

Front

What type of solution causes a cell to swell and potentially burst?

Back

A hypotonic solution causes a cell to swell and potentially burst due to water entering the cell, a process known as cytolysis.

Front

What type of molecules can easily pass through the phospholipid bilayer?

Back

Small, non-polar particles can easily move through the phospholipid bilayer.

Front

What is active transport?

Back

Active transport is the movement of molecules from areas of lower concentration to areas of higher concentration, requiring energy.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a membrane without the use of energy, typically from areas of higher concentration to lower concentration.

Front

Define hypotonic solution.

Back

A hypotonic solution has a lower concentration of solute compared to the inside of the cell, leading to water entering the cell.

Front

What is the effect of placing a cell in a hypotonic solution?

Back

Placing a cell in a hypotonic solution causes water to enter the cell, potentially leading to swelling or bursting.

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 osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
