The Study of Life |
|
Characteristics of Life (8 Characteristics) |
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 |
|
Cell |
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. |
|
Unicellular Organisms |
Composed of only ONE cell. |
|
Multicellular Organisms |
Composed of multiple cells. There are often, but not always, additional levels of organization |
|
Tissues |
Groups of similar cells working together for a common function. |
|
Organs |
Multiple tissue types working together for a common function. |
|
Organ Systems |
Multiple organs working together for a common function. |
|
Organism |
Always multicellular; eg a human |
|
Ecosystem |
A community and it's physical (abiotic; non-biological) environment. |
|
Population |
All individuals of different species living in the same place Ex: The Striped Bass population |
|
Community |
All individuals of different species living in the same place. Ex: All living organisms in a lake. |
|
Bioshere |
The Region of Earth where life exists. |
|
Emergence |
Living things may be organized, but they aren't simply the sum of their parts. They exhibit the property of emergence. |
|
Photoautotrophs |
Living things that get their energy directly from the sun. E.g. Green Plants |
|
Heterotrophs |
Get energy by digestion of other organisms or parts of other organisms. |
|
Metabolism |
The process of energy transfer. The process by which cells acquire energy and use it for maintenance, growth, and reproduction. |
|
Homeostasis |
The maintenance of relatively constant internal conditions despite changing external conditions. E.g. Body Temp |
|
How is Life Classified? |
Linnaean Hierarchy |
|
Standardization |
All names are in Latin, so the scientific names are the same EVERYWHERE no matter the language. (Latinization) |
|
The Linnaean Hierarchy (8) |
1. Domain 2. Kingdom 3. Phylum 4. Class 5. Order 6. Family 7. Genus 8. Species |
|
The Three Domains of Life |
1. Domain Archaea 2. Domain Bacteria 3. Domain Eukarya |
|
Domain Archaea |
All single-celled prokaryotic organisms, all heterotrophic |
|
Domain Bacteria |
Single-Celled prokaryotic organisms, includes common things we call bacteria, some are autotrophic some are heterotrophic. |
|
Domain Eukarya |
Some are single-cellular, but many are multicellular. There are several (4) groups: 1. Protists 2. Kingdom Fungi 3. Kingdom Plantae 4. Kingdom Animalia |
|
Protists |
Most are unicellular, some multi. |
|
Kingdom Fungi |
Some unicellular, most multi. All heterotrophic. |
|
Kingdom Plantae |
All multicellular. |
|
Kingdom Animalia |
All multicellular, all heterotrophic. |
