Chapter One

Front 1

Biology

Back 1

The study of Life

Front 2

Biosphere

Back 2

All life and the place where life exists

Front 3

Ecosystems

Back 3

All living organisms in a particular area and all the non-living components of the environment with which life interacts (such as soil, water, and light).

Front 4

Communities

Back 4

All organisms in the tide pool (iguanas, crabs, seaweed, bacteria, and others) are collectively called a community.

Front 5

Populations

Back 5

Groups of interacting individuals of one species (such as a group of iguanas).

Front 6

Organisms

Back 6

An individual living thing (such as one iguana).

Front 7

Organ systems and Organs

Back 7

What an organisms body consists of (such as circulatory, respiratory, endocrine, etc.).

Front 8

Tissues

Back 8

Each organ is made up of several different tissues. A tissue consists of a group of similar cells performing a specific function.

Front 9

Cells

Back 9

The smallest unit that can display all the characteristics of life.

Front 10

Organelles

Back 10

The functional components of cells (such as the nucleus that contains DNA).

Front 11

Molecules and Atoms

Back 11

Molecules are clusters of even smaller chemical units called atoms. Each cell consists of an enormous number of chemicals that function together to give the cell the properties of we recognize as life.

Front 12

Prokaryotic Cell

Back 12

Smaller and simpler than the eukaryotic cell. Most commonly the cells of Bacteria.
These cells do not have a nucleus to house their DNA.

Front 13

Eukaryotic Cell

Back 13

Plants and Animals have eukaryotic cells. The cell is subdivided by internal membranes into different functional compartments called organelles.
These cells do have a nucleus to house their DNA.

Front 14

Three Domains of Life

Back 14

Domain Bacteria\ Two different organisms that have
Domain Archaea/ prokaryotic cells
Domain Eukarya All eukaryotes are in this domain; includes the three kingdoms Plantae, Fungi, and Animalia.

Front 15

Plants

Back 15

Produce their own sugars and other foods by photosynthesis.

Front 16

Fungi

Back 16

Mostly decomposers, obtain food by digesting dead organisms and organic wastes.

Front 17

Animals

Back 17

Obtain food by ingesting and digesting other organisms.

Front 18

Protists

Back 18

Eukaryotes that don't fit into the other three domains. Most are single-celled, and include microscopic protozoans, such as amoebas. Can also include certain multicellular forms such as seaweeds.

Front 19

Evolution

Back 19

First discovered by Darwin and originally called "Descent with Modification".
