Fast and Curious: Cell Transport

Front

What is active transport?

Back

The pumping of molecules from an area of LOW concentration to HIGH concentration USING ENERGY.

Front

What is diffusion?

Back

The process where molecules spread from an area of HIGH concentration to LOW concentration without using energy.

Front

What is osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

What is passive transport?

Back

The movement of molecules across a cell membrane without the use of energy, including diffusion and osmosis.

Front

What is equilibrium in the context of cell transport?

Back

A state where the concentration of molecules is equal inside and outside the cell.

Front

What is endocytosis?

Back

The process by which a cell engulfs large particles or liquids by wrapping its membrane around them.

Front

What is exocytosis?

Back

The process by which a cell expels large particles or substances by vesicles fusing with the cell membrane.

Front

What happens to a cell in a hypotonic solution?

Back

Water moves into the cell, causing it to swell and potentially burst.

Front

What happens to a cell in a hypertonic solution?

Back

Water moves out of the cell, causing it to shrink.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.
