Bio 130 Exam 1 Questions and Correct Answers
All living organisms have five shared characteristics
-cells
-replication
-information
-energy
-evolution
Cells
Membrane bound cells
Replication
Reproduction
Information
Process hereditary information encoded in genes & from environment.
Energy
Acquire and use energy
Evolution
Change in characteristics of population over time
Anton van Leeuwenhoek
Father of microbiology; made superior lenses using a single lens with a magnification of
275x.
, What did Anton van Leeuwenhoek discover?
He was the first to observe and describe living microorganisms: bacteria, yeast, blood cells,
plant cells, and the life of a water drop.
Robert Hooke
First microscope studies on all things; first person to see a cell; plant cells on cork.
Cell Theory
All organisms are made of cells; all cells come from preexisting cells.
Theory
An explanation for broad patterns: evolution by natural selection, plate tectonics, atomic
theory.
Hypothesis
Testable statement that explains something observed; If, Then.
Spontaneous Generation
The belief that organisms could spontaneously arise under certain conditions
Who proved spontaneous recovery wrong
Louis Pasteur: through the boiled flask experiment with an open flask and a blocked(swan
neck) flask. The flask that didn't allow organisms in didn't have cells appear randomly.
Theodore Boveri
found chromosomes in Sea Urchin embryo had to be present for embryo development to
occur
Walter Sutton
