Spontaneous Generation | Living things come from nonliving material. |
Biogenesis | Living things come only from pre-existing living things. |
Francesco Redi | Proved that maggots come from the eggs laid by flies on meat. |
Lazzaro Spallanzani | Tried to disprove spontaneous generation by boiling broth in two flasks, covering one and leaving the other open. |
Louis Pasteur | Successfully disproved spontaneous generation by boiling broth in flasks with long, curved necks. |
Maggots | Larvae of flies. |
Manipulated variable | The one factor that a scientist changes in an experiment. |
Controlled experiment | An experiment in which all factors are identical except one. |
What was the manipulated variable in Redi's experiment? | Jar cover |
What was the control setup in Redi's experiment? | The open jar of meat |
Controlled variables | The conditions in an experiment that are kept the same. |
Experimental setup | The part of an experiment that has the manipulated variable. |
Control setup | The part of the experiment that does not have the manipulated variable. |
Why is a control setup necessary in an experiment? | It serves as a standard for comparison. |
What were the manipulated variables in Spallanzani's experiment? | Stopper and air. |
What was the manipulated variable in Pasteur's experiment? | The boiling of the broth |
What was the experimental setup in Redi's experiment? | The covered jar of meat |
What was the experimental setup in Spallanzani's experiment? | The sealed flask of broth |
What was the experimental setup in Pasteur's experiment? | The boiled flask of broth. |
What was the control setup in Spallanzani's experiment? | The open flask of broth |
What was the control setup in Pastuer's experiment? | The unboiled flask of broth |
Why wasn't Spallanzani's conclusion accepted by other scientists? | He had two manipulated variables. |
homeostasis | the organisms ability to kepp property conditions inside, regardless of what is going on outside the organism |
plants, algae, some bacteria | gets their energy directly |
animals, fungi/most bacteria | get energy indirectly like from the sun |
some bacteria | get energy from chemical compounds like sulfur and carbon dioxide, methane |

decided that any organism could be classified | Aristotle |
worlds smallest unit of organism | cell |

had the hypothesis that early Earth's atmosphere contained gasses that combined to form compounds found in early life | Oparin (1924) |
Earth's early gasses | primordial soup |
