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
