Cell Transport

Front

What is Exocytosis?

Back

Exocytosis is the process by which particles are removed from a cell by being pushed out through the cell membrane.

Front

What happens to a cell when water moves out of it during osmosis?

Back

The cell shrinks.

Front

What is Osmosis?

Back

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

Front

What is a Hypotonic Environment?

Back

A hypotonic environment is one where the concentration of solutes outside the cell is lower than inside the cell, causing water to move into the cell.

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 is Facilitated Diffusion?

Back

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

Front

What is Active Transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is a Permeable Membrane?

Back

A permeable membrane is a membrane that allows substances to pass through it.

Front

What is the role of the cell membrane in transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What occurs during Endocytosis?

Back

Endocytosis is the process by which cells take in substances by engulfing them in a vesicle.
