Cell Processes

Front

What controls what comes in and out of the cell?

Back

Cell membrane

Front

What organelle is selectively permeable?

Back

Cell membrane

Front

What does hypotonic mean?

Back

There is a greater concentration of salt inside the cell than outside, meaning water will enter and the cell will grow.

Front

What is the movement of particles from an area of high concentration to an area of low concentration called?

Back

Diffusion

Front

What does hydrophilic mean?

Back

Hydrophilic means attracting water.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solute particles, while osmosis specifically refers to the movement of water.

Front

What does selectively permeable mean?

Back

Selectively permeable means that a membrane allows certain substances to pass while blocking others.
