Cell Transport

Front

What is a hypotonic solution?

Back

A solution that causes a cell to swell because it has a lower concentration of solutes compared to the inside of the cell.

Front

What happens to a cell in an isotonic solution?

Back

The cell stays the same size because the concentration of solutes is equal inside and outside the cell.

Front

What is facilitated diffusion?

Back

A process where particles move out of a cell without using energy, through a protein channel.

Front

Why can't pure water be put into a person's veins?

Back

Because the cells would expand and could burst due to the influx of water.

Front

What is endocytosis?

Back

A type of cell transport where the cell engulfs materials from outside to bring them inside.

Front

What is exocytosis?

Back

A process where a cell expels materials to the outside by vesicles fusing with the cell membrane.

Front

What is osmosis?

Back

The movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is passive transport?

Back

The movement of substances across a cell membrane without the use of energy.

Front

What is a hypertonic solution?

Back

A solution that causes a cell to shrink because it has a higher concentration of solutes compared to the inside of the cell.

Front

What does it mean for a cell to dehydrate?

Back

It means the cell loses water and shrinks, often due to being in a hypertonic solution.
