Cellular Transport

Front

What are two types of passive transport?

Back

Osmosis and diffusion

Front

Facilitated diffusion requires:

Back

no energy

Front

What characteristic of the cell membrane allows only certain material to pass through?

Back

selective permeability

Front

Diffusion is the movement of particles:

Back

from high to low concentration

Front

The picture is an example of...

Back

active transport

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the main difference between active and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What is selective permeability?

Back

The ability of the cell membrane to allow certain substances to pass while blocking others.

Front

What is diffusion?

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What role do transport proteins play in facilitated diffusion?

Back

Transport proteins help move substances across the cell membrane without using energy.
