Common properties of life |
Order, reproduction, growth and development, energy processing, regulation, response to environment, evolutionary adaptation |
|
Order |
Ordered structure that makes up life |
|
Reproduction |
organisms reproduce their own kind |
|
Growth and Development |
inherited info in DNA that allows for the growth of organisms |
|
Energy processing |
using chemical energy to power work |
|
regulation |
regulating internal environment of an organism |
|
response to environment |
responding to environmental stimuli |
|
evolutionary adaptation |
organisms with traits best suited for environment reproduce faster than other |
|
Hierarchy of organization |
From biosphere to molecules |
|
Biosphere |
all environments on earth that support life |
|
ecosystem |
all organisms living in a certain area |
|
community |
entire array of organisms in an ecosystem |
|
population |
all invids of a particular species in an area |
|
organism |
an individual living thing |
|
organ system |
several organs cooperate for a purpose |
|
organ |
made of tisses |
|
tissues |
made of cells with specific fxns |
|
cell |
basic unit of life |
|
organelle |
membrane enclosed structure with a specific fxn in a cell |
|
molecule |
cluster of atoms held together by chem bonds |
|
emergent properties |
properties that were not present at the lower level |
|
prokaryotic cells |
first to evolve, simpler, bacteria |
|
eukaryotic cells |
evolved from prokaryotic cells, plants, animals,fungi, protists, has organelles |
|
Organisms with their environment |
*both organism and environment are affected *Animal waste returns nutrients to environment *decomposers=recyclers, so plants can absorb *two big things: recycling of chemicals and flow of energy *cycle: from air and soil to plants, to animals and decomposers, back to air and soil *energy flows in during photosynthesis which makes it chemical energy, then chemical energy is passed to consumer and then to decomposers which powers the organisms (refer to picture p5) |
|
genes |
units of inheritance that transmit info from parent to kid |
|
nucleotides |
building blocks of DNA |
|
genome |
the "library" of genetic instructions in an organism |
|
domain |
the three levels that life is organized in *bacteria, archaea-prokaryotes *Eukarya- protists(single-celled organisms) -Kingdom plantae (photo synth) -kingdom fungi- decompose dead organisms -Animals- eat other organisms |
|
evolution |
the process of change that has transformed life Darwin |
|
Natural selection |
the best qualities will be passed on to generations faster so the other qualities will die |
|
Darwin's observations and inferences |
*individuals in a population have differing traits from their parents *all species can create more offspring than the environment can support, so some will die off *individuals with the traits most suitable for the environment are more likely to survive and reproduce *due to unequal reproductive success a higher proportions of individs will have the better traits |
|
hypothesis |
proposed explanation for observations, falsifiable |
|
theory |
much broader than a hypothesis and is supported by a growing body of evidence |
