Proposed theory of evolution by the process of natual selection
Who is Charles Darwin
100
Microbiology and Chemist; develped the pasteurization process to kill bacteria in foods
Who is Lous Pasteur
100
Studied Photosynthesis; used a bell jar, a lit candle, and a plant to conclude that plants give off a substance that would keep the candle lit (Oxygen).
Who is Joseph Priestley
100
Bacteriologis known for discovery of Penicillin
Who is Alexander Fleming
100
all living things are made up of one or more cells, cells are the basic unit of structure and function, cells only come from living things (theory?)
What is The Cell Theory
200
studied the DNA molecule using a technique called X-ray diffraction
Who is Rosalind Franklin
200
theorized that populations cannot continue to grow exponentially indefinitely- limiting factors (resources) with limit popuation size
Who is Thomas Malthus
200
molecular biology and genetics; known for 1). Discovery of the double helix structure of DNA
Who are James Watson and Francis Crick
200
Studied animals; made the theory cells are building blocks of plants and animals and that cells are similar in plants and animals with different types of cells with different functions (Cell Specialization)
Who is Theodor Schwann
200
made up of units called cells, can reproduce, based on a universal genetic code, grop develop, obtain and use materials and energy, respond to thier environment, maintain a stable internal environment (homeostasis); as a group- they change over time (evolve)...
What is Characteristics of Living Things
300
First to propose a mechanism of how organisms change over time
Who is Jean-Baptiste Lamarck
300
Set up experiments that simulated early primitive Earth in order to attempt to "create" organic compounds. Were able to create Uracil and Cytosine. attemped to suggest how life could have arisen on a primitive Earth from very simple compounds.
Who are Stanley Miller & Harold Urey
300
thought that all plants are made of units, then believed plants were made of cells (1830s)
Who is Mathias Schleidon
300
tried to improve on the work of both Redi and Needham; Conclude that nonlining "gravy" did not produce lining things
Who is Lazzaro Spallanzani
300
develped binomial nomenclature; develped seven level hierarchy of classification
Who is Carolus Linnaeus
400
Founder of modern bacteriology; discovered the bacteria causing Cholera, Tuberculosis, and Anthrax; develped a test for Tuberculosis
Who is Robert Koch
400
"Father of Genetics"; researched with peas and other plants gave the basic for inheritance and cross fertilization of individuals
Who is Gregor Mendel
400
develped the first Polio vaccine
Who is Jonas Salk
400
concluded that new cells could only be produced from the divisio of existing cells (completed the Cell Theory)
Who is Rudolf Virchow
400
Studied the structure of a certain class of proteins and determined that it's shape would be a helix
Who is Linus Pauling
500
Examined plants (cork) through compound microscope and calls it a cell
Who is Robert Hooke
500
Looked at pond water through simple microscope called the Animalcules; first to document seeing living things; helped disprove spontaneous generation
Who is Anton van Leeuwenhoek
500
Physician; designed a controlled esperiment to show that flies do not spontaneously arise from decaying meat; disproved spontaneous generation
Who is Francesco Redi
500
tried to disprove Redi- Needham really thought spontaneous generatio could occur under the right conditions; tried to say that organisms arise from "gravy"
Who John Needham
500
concluded that aquatic plants gave off oxygen bubbles only in the day and not at night; therefore, plants need sunlight to make oxygen
Who is Jan Ingenhousz
