Functions are the physical traits that organisms develop.

Structures are the adaptations that perform specific functions. (correct)

Structures are irrelevant to an organism's survival.

Study Notes

Lesson 2: Structure and Function

Organisms have developed various ways to survive.
Structures (body parts) have specific functions.

Structures and Adaptations

Structures are physical traits that help an organism survive.
Function is the job the structure does to keep the organism alive.
A good example is lungs (structure) and breathing (function).

Structure vs. Function Game

Students are divided into groups.
Each group gets structure and function cards.
The first team to correctly identify the structure or function earns a point.
The winning group is the one with the most points.

Old Dead Guy Spotlight: Charles Darwin

Charles Darwin was a scientist.

Finches Video

Different types of finches are shown (Geospiza magnirostris, Geospiza fortis, Geospiza parvula, Certhidea olivasea).
Images of finch beaks are presented.

Charles Darwin's Quote

"Some adaptations will increase an organism's chance of survival in a specific environment."
"Organisms that survive long enough to reproduce will pass successful adaptations on to their offspring."
"Over time, the population will change to have more advantageous adaptations."
