All living things are made up of ______?
cells
is the idea that life could appear from non-living material
Spontaneous Generation
Spontaneous Generation is also known as _____?
abiogenesis
first person to propose the idea of Spontaneous Generation in 4th century
Aristotle
is the belief that life originates from preexisting life.
Biogenesis
He concluded that life arose from living matter and not from spontaneous generation.
Francisco Redi’s Experiment
a Scottish clergyman and naturalist showed that microorganisms flourished in various soups that had been exposed to the air.
John Needham
he concluded that life in broth caused Spontaneous Generation to occur, he did not heat it long enough to kill all the microbes from the broth.
Needham’s Experiment
an Italian abbot & biologist tried several variations on Needham’s soup experiments.
Lazzaro Spallanzani
he designed flasks with long, specially curved, swanlike necks.
Louis Pasteur
He concluded that life occurred from something that entered the unsealed flask that it was the one responsible for life to grow.
Spallanzani’s Experiment
sterilized broth to be exposed to fresh air from the outside, but any microorganisms from the air would be trapped in a pool of water in the neck. New bacteria appear only when produced by existing bacteria
Pasteur’s Experiment
It is believed that life forms and everything and the universe were created through supernatural power rather than naturalistic means.
Divine Creation
a Russian biochemist, proposed the idea on the first organic compounds
Alexander Oparin
gases from earth’s atmosphere, under high temperatures, formed simple organic compounds
Spontaneous Origin
living things created other living things
Biogenetic Theory
