Passive Transport Review

Front

What is osmosis?

Back

The diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

Which of the following is NOT a type of passive transport?

Back

Endocytosis.

Front

What is equilibrium in the context of cell membranes?

Back

Equal amount of substance on either side of the membrane.

Front

What does it mean if a cell is selectively permeable?

Back

It allows some substances to pass through while blocking others.

Front

What type of solution causes blood cells to shrink?

Back

Hypertonic solution.

Front

Define diffusion.

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses protein channels to help move substances across a membrane.

Front

What is a semi-permeable membrane?

Back

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

Front

What happens to a cell in a hypotonic solution?

Back

The cell swells as water enters due to lower solute concentration outside the cell.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.
