What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. Water is a common example of a solvent.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. Salt is a common example of a solute.

Front

What does isotonic mean in relation to cell transport?

Back

Isotonic refers to a solution where the concentration of solutes is the same inside and outside the cell, resulting in no net movement of water.

Front

Why is diffusion important for cells?

Back

Diffusion allows cells to take in necessary materials and expel waste without using energy.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, relying on concentration gradients.

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.

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.

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.

Front

What is the role of the cell membrane in transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move substances across the cell membrane.
