Passive Cell Transport

Front

What is passive cell transport?

Back

Passive cell transport is the movement of substances across a cell membrane without the use of energy, relying on concentration gradients.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, a cell will gain water, potentially leading to swelling or bursting.

Front

What is osmosis?

Back

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

Front

What is diffusion?

Back

Diffusion is the movement of solute particles from an area of higher concentration to an area of lower concentration.

Front

What is the main difference between osmosis and diffusion?

Back

Osmosis involves the movement of water, while diffusion involves the movement of solutes.

Front

What occurs when equilibrium is reached in diffusion?

Back

When equilibrium is reached, particles continue to move, but there is no net change in concentration.

Front

Is energy required for diffusion?

Back

No, diffusion does not require energy; it is a passive process.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas.

Front

What is a hypertonic solution?

Back

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

Front

What is an isotonic solution?

Back

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