Passive Transport: Simple, Facilitated, and Osmosis

Front

What is the process a cell uses to maintain stable internal conditions when the environment around it changes?

Back

Homeostasis

Front

What is the term for a solution that has a higher concentration of solutes compared to the inside of a cell, causing water to move out of the cell?

Back

Hypertonic solution

Front

What role do membrane proteins play in addition to transporting molecules across the cell membrane?

Back

Helping the cell communicate with the outside.

Front

What is the term for the diffusion of water across a selectively permeable membrane?

Back

Osmosis

Front

What is the process called when larger molecules diffuse through the cell membrane with the help of a transport protein and no energy?

Back

Facilitated Diffusion

Front

What is the difference between passive transport and active transport?

Back

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

Front

What is simple diffusion?

Back

The movement of small or nonpolar molecules across the cell membrane from an area of high concentration to an area of low concentration without the use of energy.

Front

What is a selectively permeable membrane?

Back

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

Front

What happens to a cell placed in a hypotonic solution?

Back

The cell will swell as water moves into it due to a lower concentration of solutes outside the cell.

Front

What is isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.
