unit 1 main idea

The smallest unit of an element that has the chemical properties of the element.

Atoms

Atoms bond with each other to form

Molecules

polymer such as a polypeptide consists of many molecules bonded together and is called

Macromolecule

Where do we find carbohydrates proteins and nucleic acid (DNA and RNA)

Living organisms

Simplest unit of life

Cell

surrounded by a membrane and contains a variety of molecules and macromolecules.

Cell

organisms are composed of one cell

Unicellular

What types of organisms are made more of one cell

multicellular

1. In multicellular organisms, many cells of the same type associate with each other to form

Tissues

two or more types of tissue and carries out a particular function

Organs

Organism of the same species

Population

Different species with each other

Community

Organisms interact in the same habitat

Ecosystem

Vast region

Biosphere

Why did diversity of life evolved

Evolution, mutation, natural selection

Biologists often say "structure determines function." This core concept pertains to very tiny biological molecules and to very large biological structures. The feet of different birds provide a striking example. Aquatic birds have webbed feet that function as paddles for swimming. By comparison, the feet of nonaquatic birds are not webbed and are better adapted for grasping food, perching on branches, and running along the ground. The structure of a bird's feet, webbed versus nonwebbed, is a critical feature that affects their function.

This is an example of

Structure and function

basic units of structure define the function of all living things

Structure and function

Growth and behavior of organisms are activated through the expression of genetic information

Information flow, exchange, and storage

Biological processes based on chemical transformation pathways and governed by laws of thermodynamics

Pathways and transformations of energy and matter

Living systems are interconnected and interacting
