Cell Transport Vocab

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically moving from an area of high concentration to an area of low concentration.

Front

What is the direction of movement in passive transport?

Back

In passive transport, substances move from high concentration to low concentration.

Front

What is osmosis?

Back

Osmosis is the process by which water molecules diffuse across a selectively permeable membrane.

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

What is the direction of movement in active transport?

Back

In active transport, substances move from low concentration to high concentration.

Front

What is required for active transport to occur?

Back

Active transport requires energy, often in the form of ATP.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell forms a vesicle around unwanted particles and expels it out of the cell.

Front

What is the difference between passive and active transport?

Back

The main difference is that passive transport does not require energy and moves substances from high to low concentration, while active transport requires energy and moves substances from low to high concentration.

Front

What role do cell membranes play in transport processes?

Back

Cell membranes act as barriers that regulate the movement of substances in and out of the cell, allowing for selective permeability.

Front

What is facilitated diffusion?

Back

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