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
