Moving Cellular Material

Front

What is passive transport?

Back

Passive transport is the movement of substances through a cell membrane without using the cell's energy.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules only through a membrane.

Front

What happens when there is more water in a plant than in the air?

Back

Water will diffuse from the plant into the air.

Front

What is facilitated diffusion?

Back

Facilitated diffusion allows molecules to pass through a cell's membrane using transport proteins.

Front

What are transport proteins?

Back

Transport proteins are proteins that help move substances across a cell membrane.

Front

What is concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance between two areas.

Front

What is the role of the cell membrane?

Back

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

Front

What is active transport?

Back

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

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances.
