Cell Transport

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What is a hypotonic environment?

Back

An environment where the percentage of water is higher outside the cell than inside, causing too much water to enter the cell and potentially burst it.

Front

What are the two types of cell transport?

Back

Passive transport and Active transport.

Front

What is active transport?

Back

The movement of materials across a cell membrane that requires energy.

Front

Why do plant cells not burst in a hypotonic solution?

Back

Plant cells have a cell wall that provides structural support.

Front

What is passive transport?

Back

The movement of substances across a cell membrane without the use of energy.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a hypertonic environment?

Back

An environment where the percentage of solute is higher outside the cell than inside, causing the cell to lose water and shrink.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to move molecules across the membrane.

Front

What role do cell membranes play in transport?

Back

Cell membranes regulate what enters and exits the cell, maintaining homeostasis.
