Cell Transport Flashcard

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and leaves the cell.

Front

What occurs to a plant cell in a hypotonic solution?

Back

The plant cell swells due to water entering the cell.

Front

Define isotonic solutions.

Back

Isotonic solutions have the same solute concentration.

Front

What is diffusion?

Back

Diffusion is the process that moves materials from high concentration to low concentration.

Front

Which process is NOT a form of passive transport?

Back

Endocytosis is not a form of passive transport.

Front

What is osmosis?

Back

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

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher solute concentration than the cell, causing it to shrink; hypotonic solutions have a lower solute concentration, causing the cell to swell.

Front

What is active transport?

Back

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

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane assist in transport, communication, and structural support.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a membrane via specific transmembrane integral proteins.
