Characteristics of Life Review
-
Matching
- Redi: Disproved spontaneous generation by showing maggots didn't spontaneously arise from meat
- Needham: Performed an experiment that seemed to support spontaneous generation, but his methods weren't rigorous.
- Spallanzani: Repeated/re-designed Needham's experiment to eliminate potential contamination issues, disproving spontaneous generation.
- Pasteur: Conducted experiments using swan-necked flasks to further solidify the rejection of spontaneous generation
- Cell: The basic unit of life, made of one or more cells
- Autotroph: Organism that creates its own food
- Multicellular: Living organism comprised from multiple/more cells
- Metabolism: Chemical processes that occur within an organism
- Unicellular: Living organism comprised of only one cell
- Biogenesis: The creation of living organisms from other living organisms
- Abiogenesis: The mistaken/unsupported idea that life can arise from non-living matter (spontaneous generation)
- Asexual reproduction: Creation of offspring from one parent.
- Heterotroph: Organisms that get energy from eating other organisms.
