Unit 3: Cells Flashcard 2 Pulse Check - 23

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, leading to the movement of water out of the cell.

Front

What is a eukaryotic cell?

Back

A eukaryotic cell is a type of cell that has a true nucleus and membrane-bound organelles.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is a hypotonic solution?

Back

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

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes compared to another solution, resulting in no net movement of water.

Front

What is diffusion?

Back

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

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What happens to a red blood cell in a hypotonic solution?

Back

In a hypotonic solution, a red blood cell will swell and may burst due to the influx of water.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What is equilibrium in the context of osmosis?

Back

Equilibrium is reached when the concentration of solutes is equal on both sides of the membrane, resulting in no net movement of water.
