Biology

Back 1

The Study of Life

Front 2

Characteristics of Life

(8 Characteristics)

Back 2

1. Organized

2. Emergence

3. Require and Use Energy

4. Maintain Homeostasis

5. Respond to Stimuli

6. Grow

7. Reproduce

8. Posses Adaptations to Environment

Front 3

Cell

Back 3

1. Basic Unit of Life

2. The smallest unit that remains all of the basic properties of life.

3. All living things are composed of one or more cells.

Front 4

Unicellular Organisms

Back 4

Composed of only ONE cell.

Front 5

Multicellular Organisms

Back 5

Composed of multiple cells.

There are often, but not always, additional levels of organization

Front 6

Tissues

Back 6

Groups of similar cells working together for a common function.

Front 7

Organs

Back 7

Multiple tissue types working together for a common function.

Front 8

Organ Systems

Back 8

Multiple organs working together for a common function.

Front 9

Organism

Back 9

Always multicellular; eg a human

Front 10

Ecosystem

Back 10

A community and it's physical (abiotic; non-biological) environment.

Front 11

Population

Back 11

All individuals of different species living in the same place

Ex: The Striped Bass population

Front 12

Community

Back 12

All individuals of different species living in the same place.

Ex: All living organisms in a lake.

Front 13

Bioshere

Back 13

The Region of Earth where life exists.

Front 14

Emergence

Back 14

Living things may be organized, but they aren't simply the sum of their parts. They exhibit the property of emergence.

Front 15

Photoautotrophs

Back 15

Living things that get their energy directly from the sun.

E.g. Green Plants

Front 16

Heterotrophs

Back 16

Get energy by digestion of other organisms or parts of other organisms.

Front 17

Metabolism

Back 17

The process of energy transfer. The process by which cells acquire energy and use it for maintenance, growth, and reproduction.

Front 18

Homeostasis

Back 18

The maintenance of relatively constant internal conditions despite changing external conditions.

E.g. Body Temp

Front 19

How is Life Classified?

Back 19

Linnaean Hierarchy

Front 20

Standardization

Back 20

All names are in Latin, so the scientific names are the same EVERYWHERE no matter the language. (Latinization)

Front 21

The Linnaean Hierarchy

(8)

Back 21

1. Domain

2. Kingdom

3. Phylum

4. Class

5. Order

6. Family

7. Genus

8. Species

Front 22

The Three Domains of Life

Back 22

1. Domain Archaea

2. Domain Bacteria

3. Domain Eukarya

Front 23

Domain Archaea

Back 23

All single-celled prokaryotic organisms, all heterotrophic

Front 24

Domain Bacteria

Back 24

Single-Celled prokaryotic organisms, includes common things we call bacteria, some are autotrophic some are heterotrophic.

Front 25

Domain Eukarya

Back 25

Some are single-cellular, but many are multicellular. There are several (4) groups:

1. Protists

2. Kingdom Fungi

3. Kingdom Plantae

4. Kingdom Animalia

Front 26

Protists

Back 26

Most are unicellular, some multi.
Some autotrophic, some heterotrophic.

Front 27

Kingdom Fungi

Back 27

Some unicellular, most multi.

All heterotrophic.

Front 28

Kingdom Plantae

Back 28

All multicellular.
Almost all autotrophic.

Front 29

Kingdom Animalia

Back 29

All multicellular, all heterotrophic.
