Cells and Cell Transport

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically moving from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

What defines a prokaryotic cell?

Back

A prokaryotic cell is defined by the absence of membrane-bound organelles and a nucleus.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane using energy, typically moving from an area of low concentration to an area of high concentration.

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain substances to pass through while blocking others.

Front

What is endocytosis?

Back

Endocytosis is the process by which a cell engulfs material from its environment, bringing it into the cell.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials to the outside environment.
