Passive Transport Review

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy by the cell.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What happens to a cell in a hypertonic solution?

Back

Water will move out of the cell, causing it to shrink.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What happens to a cell in a hypotonic solution?

Back

Water will move into the cell, causing it to swell.

Front

What is an isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What role does the cell membrane play in passive transport?

Back

The cell membrane regulates which materials enter and leave the cell, facilitating passive transport.

Front

What is homeostasis?

Back

Homeostasis is the process by which a cell maintains a stable internal environment.
