The hypothetical process by which living organisms develop from nonliving matter.
What is spontaneous generation?
When Redi conducted his experiment.
What is the 1600's?
The early atmosphere lacked this.
What is oxygen?
This form of respiration allows a lot of energy to be released from glucose molecules.
What is aerobic respiration?
The country where 3.5 billion year old microfossils were found.
What is Australia?
He was able to disprove the theory that maggots could be spontaneously generated from meat.
Who was Francis Redi?
Where life comes from!!
What is life?
The first prokaryotes must have been this type of organism to survive in an oxygen free environment.
What is anaerobic?
Oxygen is not required for this form of respiration.
What is anaerobic respiration?
Scientists believe the Earth form from theses.
What are gas and dust?
Spallanzani’s opponents said that by boiling the flask he was destroying this in the air inside the flask!!
What is the vital force?
The solar system formed.
What is 5 billion years ago?
The first prokaryotes did not make their own food so they were considered this type of organism.
What is heterotrophic?
The oxygen released into the atmosphere formed a layer that was able to prevent a lot of this from reaching the Earth's surface.
What is ultraviolet radiation?
The process the first autotrophs used to produce glucose.
What is chemosynthesis?
The theory that life comes from life was/is the cornerstone of biology!!!
What is biogenesis?
When the planets formed.
What is 4,6 billion years ago?
The main reason autotrophs are believed to have evolved.
What is competition for food?
The layer that protects the Earth from harmful rays from the Sun.
What is the ozone layer?
These cells do not contain membrane bound organelles.
What are prokaryotes?
The man who did this experiment:
Who is Louis Pasteur?
When the oceans formed.
What is 3.9 billion years ago?
The theory the eukaryotes evolved through a process whereby different types of free-living prokaryotes became incorporated inside larger prokaryotic cells and eventually developed into mitochondria, chloroplasts, and possibly other organelles.
What is the endosymbiont hypothesis?
A relationship in which both organism benefit,
What is a symbiotic relationship?
The first living things likely formed here.
What is the ocean?
The man who did this experiment:
Who was Spallanzani?
The number of years the Earth has existed.
What is 4.6 BYA?
Organism that can produce their own food
What are autotrophs?
Mitochondria and chloroplasts may have developed from these.
What are internalized bacteria?
Chloroplasts are similar in size and appearance to these colorful bacteria.
What are blue-green bacteria?
The man who did this experiment:
Who was Francesco Redi?
Another term for microscopic fossils
What are microfossils?
The four developments had to occur in order for life to come into being.
What are the formation of simple organic compounds, the formation of complex organic compounds, the concentration and enclosing of organic compounds and the evolution of growth, metabolism and reproduction?
Fossils evidence indicates that eukaryotes evolved approximately this long ago!!
What is 1 BYA?
All organic compounds contain this element.
What is carbon?
