spontaneous generation Flashcards
What is the theory of spontaneous generation?
The theory that living organisms can form from non-living matter.
What did Pasteur and other scientists prove about spontaneous generation?
They proved that spontaneous generation is false.
What did Remak discover about cell formation?
Every cell is formed by the division of a pre-existing cell.
Where did the first cell come from?
The first cell must have developed from non-living material by natural processes.
Can a structure as complex as a cell arise from non-living material by natural means?
Yes, if there were a series of intermediate stages over time, the origin of the first cell becomes more feasible.
What developments are required for the origin of cells?
- Catalysis – to control chemical reactions.
- Self-assembly – carbon compounds form polymers.
- Compartmentalization – a membrane forms to enclose cell contents.
- Self-replication – molecules must replicate for inheritance and persistence.
