Front

What is osmosis?

Back

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

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What does permeable mean?

Back

Permeable means that substances can pass through a material or membrane.

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 endocytosis?

Back

Endocytosis is the process by which cells take in large particles or liquids by engulfing them in a membrane.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel large particles or liquids by vesicles fusing with the cell membrane.

Front

What is an isotonic solution?

Back

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

Front

What is a hypertonic solution?

Back

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

Front

What is a hypotonic solution?

Back

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

Front

What is the role of the cell membrane in osmosis?

Back

The cell membrane is selectively permeable, allowing water to pass through while controlling the movement of solutes.
