Passive transport – movement of particles across a cell membrane (high to low) without the use of energy (diffusion, osmosis)
Active transport – movement of particles across a membrane from high concentration to low – takes ENERGY
Function– the job the part does.

Before Charles Darwin wrote about how he thought life on Earth evolved, most people believed that humans, and plants and animals had not changed since life began on this planet. When Darwin visited Galapagos, he found that many birds, animals, plants and reptiles had developed differently from the same ancestors. Over millions of years they have slowly adapted to the different environments around them by the process called evolution.
There are thirteen species of Darwin's finch, a small sparrow-like bird, in the Galapagos Islands. Each species has adapted - or evolved - depending on the type of food that it feeds on. This is shown by the different beak shapes.
For example, the large ground finch has developed a broad, wide beak, for cracking hard seeds. Other types of finch feed on insects, some remove ticks from tortoises, and one even pecks at seabirds and feeds on their blood! Each finch species has evolved according to its particular food source.
