Cell Transport

Front

What is active transport?

Back

Active transport is the movement of particles from an area of lower concentration to an area of higher concentration, requiring energy input.

Front

What is passive transport?

Back

Passive transport is the movement of particles across a membrane from an area of higher concentration to an area of lower concentration without the use of energy.

Front

What is osmosis?

Back

Osmosis is a type of passive transport that specifically refers to the movement of water molecules through a semipermeable membrane.

Front

What does isotonic mean in terms of cell solutions?

Back

Isotonic refers to a solution that has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What does hypotonic mean in terms of cell solutions?

Back

Hypotonic refers to a solution that 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 in terms of cell solutions?

Back

Hypertonic refers to a solution that has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is the independent variable in an experiment?

Back

The independent variable is the variable that is changed on purpose to test its effect on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the variable that is being tested, counted, or measured in response to changes in the independent variable.

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.

Front

What is the role of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, maintaining homeostasis and protecting the cell's internal environment.
