Cell Transport

Front

What is diffusion?

Back

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration until they are evenly distributed.

Front

What is osmosis?

Back

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

Front

What does hypotonic mean?

Back

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

Front

What does hypertonic mean?

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.

Front

What is isotonic?

Back

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

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, using energy.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water enters the cell, causing it to swell and potentially burst.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water leaves the cell, causing it to shrink.
