criteria for life
|
ALL LIFE:
#1 contains deoxyribonuclei, or DNA, #2 metabolism #3 receptors #4 can reproduce |
|
metabolism
|
all processes where organisms convert energy & matter from outside sources & is used to sustain life functions
|
|
anabolism
|
all processes where organisms use energy & simple chemical building blocks to produce large chemicals & structures necessary for life
|
|
catabolism
|
all processes where organisms break down chemicals to produce energy & simple chemical building blocks
|
|
photosynthesis
|
process by which green plants & some other organisms use energy of sunlight & simple chemicals to produce their own food
|
|
herbivors
|
organisms that eat only plants
|
|
carnivors
|
organisms that eat only
other organisms other than plants |
|
omnivors
|
organisms that eat both plants and other organisms
|
|
producers
|
organisms that produce their own food
|
|
consumers
|
organisms that eat living producers & or other consumers for food
|
|
decomposers
|
organisms that break down the dead remains of other organisms
|
|
autotrophs,(self-feeder)
|
organisms that are able to make their own food
|
|
heterotrophs,(other-feeder)
|
organisms that depend on other organisms for their food
|
|
receptors
|
special structures that allow living organisms to sense the conditions of their internal & external enviroment
|
|
asexual reproduction
|
reproduction acomplished by one organism
|
|
sexual reproduction
|
reproduction that requires two organisms
|
|
inheritance
|
the process by which physical & biological charcteristics are transmited from parent(s) to offspring
|
|
mutation
|
an abrupt & marked change in DNA of an organism compared to parent(s)
|
|
hypothesis
|
educated guess that attempts to explain an observation or answer a question
|
|
theory
|
a hypothesis that has been tested w/ alot of data
|
|
scientific law
|
a theory that has been tested by generations of consistent large amounts of data
|
|
spontaneous generation
|
living things appear from nonliving things
|
|
microorganisms
|
organisms too small to see w/ naked eye
|
|
abiogenesis
|
the idea that long ago, very simple life forms spontaneously appeared through chemical reactions
|
|
classifactions:
|
Kingdom, Phylom, Class, Order, Family, Genus, & Species
|
|
5 Kingdom System
|
1. Monera- one or many prokaryotic
2. Protista- one or many eukaryotic 3. Fungi- decomposers, eukaryotic 4. Plantea- autotrophs, eukaryotic 5. Animalia- heretrophs, eukaryotic |
|
3 Kingdom System
|
1. Archaea- prokaryotic organisms in exteme enviroments
2. Bacteria- prokaryotic organisms in normal enviroments 3. Eukarya- Protista, Fungi, Plantea, & Animalia |
|
prokaryotic
|
a cell w/ no distinct, membrane-bounded organelles
|
|
eukaryotic
|
a cell w/ distinct, membrane-bounded organelles
|
|
organells
|
structure inside cell
|
|
species
|
a unit of one or more population of individuals that can reproduce under normal circumstances, produce fertal offspring, & are reproductivly isolated from other such units
|
|
taxonomy
|
science of classifying organisms
|
|
binomial nomenclature
|
naming an organismm w/ its genus & species name
|
|
evolution
|
all life formed from simple life forms that lived for billions of years, & formed through abiogenesis
|
|
baraminology
|
study of created things
|
|
Scientific Method
|
make observation,
form hypothesis to explain observation, collect data to test hypothesis, if data is consistent w/ hypothesis it becomes a theory, continue to test theory w/ generations of data, if data is consistent, the theory becomes a scientific law |
