Fast and Curious: Cell Transport

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, aiming to reach equilibrium.

Front

What is the purpose of diffusion?

Back

The purpose of diffusion is to reach equilibrium by moving molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is active transport?

Back

Active transport is the movement of molecules from an area of low concentration to an area of high concentration using energy.

Front

What is endocytosis?

Back

Endocytosis is the process by which a cell engulfs material from its environment, bringing it into the cell.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials to the outside environment.

Front

What does equilibrium mean in the context of cell transport?

Back

Equilibrium refers to a state where the concentration of molecules is the same inside and outside the cell.

Front

What is a semipermeable membrane?

Back

A semipermeable membrane is a barrier that allows certain molecules to pass through while blocking others.

Front

What happens when a cell is in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.

Front

What happens when a cell is in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.
