What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the need for energy input, relying on concentration gradients.

Front

Which process is NOT a type of passive transport?

Back

Endocytosis is NOT a type of passive transport.

Front

What is diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

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

Front

What does osmosis specifically move across a membrane?

Back

Osmosis specifically moves water across a membrane.

Front

Can diffusion occur in both plants and animals?

Back

Yes, diffusion can occur in both plants and animals.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move molecules across the cell membrane.

Front

What is the main difference between diffusion and osmosis?

Back

The main difference is that diffusion refers to the movement of all types of molecules, while osmosis specifically refers to the movement of water.

Front

What role do semi-permeable membranes play in passive transport?

Back

Semi-permeable membranes allow certain molecules to pass through while blocking others, facilitating selective transport.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in concentration of a substance across a space, driving the movement of molecules from high to low concentration.
