Active and Passive Transport

Front

What is diffusion?

Back

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. It is a form of passive transport.

Front

What happens to an egg placed in pure water for 48 hours?

Back

The egg will gain water and swell because it is in a hypotonic environment.

Front

What is a hypotonic environment?

Back

A hypotonic environment is a solution with a lower concentration of solutes compared to the inside of a cell, causing water to move into the cell.

Front

What type of transport is engulfing?

Back

Engulfing is a type of active transport where a cell membrane surrounds and takes in large particles or other cells.

Front

In which solution will water move into a cell?

Back

Water will move into a cell in a hypotonic solution.

Front

What is passive transport?

Back

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

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy (ATP) to occur.

Front

What is osmosis?

Back

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

Front

What is a hypertonic solution?

Back

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

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.
