Passive Transport

Front

What is Passive Transport?

Back

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

Front

What does it mean when a cell is in Equilibrium?

Back

Equilibrium is the state when the concentration of water inside and outside the cell is equal.

Front

What is Osmosis?

Back

Osmosis is the diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

How do water molecules move during Osmosis?

Back

Water molecules move out of the cell when the outside concentration is higher, causing the cell to shrink.

Front

Does Passive Transport require energy?

Back

No, Passive Transport does not require energy.

Front

What is a Semi-Permeable Membrane?

Back

A Semi-Permeable Membrane allows certain substances to pass through while blocking others.

Front

What is Diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What happens to a cell in a hypertonic solution?

Back

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

Front

What happens to a cell in a hypotonic solution?

Back

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

Front

What is the difference between Osmosis and Diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any particles.
