Structure Function

Structure, Function, Adaptation

By Lauren Olivares

Structure- the form or the parts that make up an organism.

​

Example- legs, beak, tail, feathers, hands, leaves, thorns

​

Structure is how something is made​

​

​Some text here about the topic of discussion.

Structure

Function- is the purpose of the structure.

​

Example- thorns protect plants, ​ elephant trunks help them drink water

​

Function is what it does.​

​

​Some text here about the topic of discussion.

​Function

Adaptation- is a change that helps an organism survive in its environtment.

​

There are 2 types of Adaptations

1. Structure/Physical

2. Behavior​

​

​Some text here about the topic of discussion.

Adaptation

Different body parts that helps an organism survive.

Each body part serves a function or purpose.​

​

Examples: ​fins, sharp teeth, claws, camoflage

​

​Some text here about the topic of discussion.

​Structure or Physical Adaptation

Behaviors or things animals do to help them survive.

​

Examples ​- migration, hibernations, dormancy.
